MID-PACIFIC OCEANOGRAPHY, PART VIII, MIDDLE LATITUDE WATERS,
JANUARY-MARCH 1954
By James W. McGary, Oceanographer ,
and
E. D. Stroup, Physical Science Aid
This report is concerned with
cruise 25 of the M/V Hugh M. Smith, the
first of a series of surveys planned to des-
cribe the oceanography of the central temper-
ate North Pacific by the Pacific Oceanic Fish-
ery Investigations, U. S. Fish and Wildlife
Service. These studies are designed to des-
cribe the physical environment in the region
north of Hawaii in connection with investiga-
tions on the albacore tuna, Germo alalunga
(Bonnaterre). This cruise was concurrent
with fishing by the John R. Manning, cruise
23, the results of which will appear separately.
The survey, made during January-
March 1954, covered an area bounded roughly
by 141 and 165 W. longitude, and by 24 and
38 N. latitude (fig. 1). Serial measurements
of temperature, salinity, oxygen, and inorgan-
ic phosphate were made to a depth of approxi-
mately 1,200 meters; quantitative zooplankton
collections were taken by oblique tows through
the upper 200 meters and meteorological data
were recorded. The surface currents were
measured with the Geomagnetic Electrokine-
tograph during part of the cruise. This report
presents the tabulated station data (except for
the results of the plankton collections which
will appear separately), meridional sections,
and horizontal plots of oceanic and meteorolo-
gical features, and brief analyses and descrip-
tions of the results.
PROCEDURES
The vessel equipment and the
methods of collecting and correcting the raw
data have been described in previous reports
(Cromwell 1951, Stroup 1954); the methods of
analysis of the observed data leading to their
presentation as meridional sections have also
been described in detail (Stroup 1954). In es-
sence, the analysis attempts to use all the
data to achieve a comprehensive, consistent
description of the distributions of the several
variables. In the analysis of the individual
stations, the vertical distribution of each vari-
able is referred to temperature, as this is the
only quantity measured continuously with depth.
Rather than analyze each station independently ,
observed values from nearby stations are
considered during the construction of the sta-
tion curves. The vertical sections of density
(sigma-t) distribution are influenced by the
structure of the detailed bathythermograph
(BT) temperature sections, and the sections
of the other quantities are in turn influenced
by the sigma-t distribution, in accordance with
the principles of isentropic analysis. Insofar
as possible, no quantity is considered inde-
pendently of the over-all description.
The horizontal plots (excepting figs.
2-4) are based on a simple conic projection
o o
with standard parallels at 25 and 4 5 N. ; the
distance scale is the same as that used in the
meridional sections. There is slight distortion,
nowhere greater than about 1 percent, along
the central and marginal parallels of latitude .
The horizontal plots are based on values inter-
polated from the station curves and, whenever
possible, the meridional sections were used to
determine the contour intervals between stations.
The meteorology of the region is
discussed in somewhat greater detail than in
previous reports. The storm tracks were taken
from the daily (1200Z) surface weather charts
published by the U. S. Weather Bureau. The
monthly positions of the limits of the trades and
westerlies and the positions of the "Eastern
North Pacific High" and the "Aleutian Low"
(these are average, climatological features)
during the period the cruise were obtained from
the monthly average charts supplied by the Ex-
tended Forecast Section of the U. S. Weather Bu-
reau. The long-term average monthly positions
of these features are from Technical Paper No.
21, U. S. Weather Bureau, "Normal Weather
Charts for the Northern Hemisphere, " and from
the U. S. Navy Hydrographic Office Pilot Charts
for the North Pacific (H.O. 1401).
CLIMATE AND WEATHER
The oceans are a flexible medium
whose circulation, temperature structure, sali-
nity, and dissolved oxygen content are largely
dependent upon the exchange of energy between
the atmosphere and water. A discussion of
1
oceanographic features of an area should not
be undertaken without an understanding of at
least the major features of climate and wea-
ther. The general ocean currents are more
or less directly produced by the prevailing
winds (Sverdrup 194 3, p. 92) and hence should
show some seasonal changes as the intensity or
direction of the winds change. Locally, the
major source of change in the thermal struc-
ture of the water is the mixing induced by wind
waves or current shear caused by local vari-
ance in wind stress. Over wide areas, the
major sources of change are from variations
in the rate of exchange of heat by conduction,
evaporation, precipitation, and radiation .
These changes occur when water is transported
by the general currents from warmer to colder
regions (low to high latitudes), or vice versa,
or when the atmospheric circulation carries
air to an ocean area having a different temper-
ature. Extensive changes in salinity in the
open ocean can be caused only by an exchange
of moisture with the atmosphere. Thus, we
must consider features in the atmospheric or
oceanic circulation which would be conducive
to evaporation from the sea, such as the move-
ment of cold air over warm water, or move-
ment of warm water to a region of cooler air,
or features conducive to precipitation, such as
areas of frontal activity in the air. The dis-
solved oxygen capacity of the sea is a function
of temperature, salinity, and vapor tension,
as well as pressure, and is therefore subject
to modification by the exchange of heat or
moisture that takes place at the sea surface.
The mean monthly sea level
pressure charts (U.S.W.B. 1952) showthatthe
wind and weather of the North Pacific are domi-
nated by a subtropical pressure maximum,
commonly known as the Eastern North Pacific
High or the North Pacific anticyclone, and a
subpolar pressure minimum, commonly known
as the Aleutian Low. These features define
the principal wind belts. They undergo a north-
ward shift from winter to summer and during
this migration the subpolar low diminishes ,
practically disappearing during June and July,
and the subtropical high increases (Namias
1953, Byers 1944).
The Eastern North Pacific High is
the most permanent of the climatic features of
the North Pacific. Its center is characterized
by light winds and little or no storminess, but
its migration affects the storm paths of the en-
tire ocean. If the center is displaced farther
north than normal, storms occur farther north;
if it is displaced farther south, the storms
sweep across the oceans at more southerly
latitudes.
Actually, the Eastern North Pacific
High is a great area of subsiding air. The ef-
fects of subsidence are most noticeable in the
eastern sector as a result of air that has de-
scended as it swept around the cell from the
northwest and north. On the south side, as the
air joins the trades, it begins to ascend again
until it reaches a high point on the southwestern
part of the cell. On the west side of the cell,
fronts may be formed as the warmer air from
the cell encounters the cooler air to the north.
As a result of this circulation the areas of
greatest evaporation are likely to be found to the
east of the cell and areas of greatest precipitation
to the west.
The Aleutian Low is maintained by
intermittent outbursts of cold polar air which is
steadily generated in the interior of Asia during
the winter months. The greatest percentage
(about 70 percent) of these outbreaks occur in the
region of Japan, the China Sea, or the Yangtze
Valley (Byers 1934). As the cold air moves
over the warm sea and encounters the warmer
tropical air masses, strong cyclonic vortices
are formed. They have well-marked warm
fronts of advancing tropical air with open warm
sectors and well-defined cold fronts. The normal
path of these storm centers is in a northeasterly
direction. In most cases the fronts have occluded
and died out by the time they reach Alaska. How-
ever, they are occasionally regenerated by in-
fluxes of cold air from the Yukon Valley. The
cyclonic disturbances tend to occur in cycles,
that is, large cyclones are followed by progres-
sively smaller ones, each carrying the cold
front farther toward the Equator than the pre-
ceding one until finally polar air flows directly
into the trade wind region. Precipitation occurs
when the warm, moist air of tropical or sub-
tropical origin is forced to ascend over the
colder, denser air (Byers 1944).
During the summer months, the
Eastern North Pacific High is well developed and
is the predominant climatic feature of the North
Pacific. The mean position of the center of the
high lies within the area covered by cruise 25
from April to September and just to the east of
the area during the remainder of the year. Con-
sequently, the prevailing winds of the area vary
considerably from season to season as a result of
the migration and fluctuation of the high. During
the period from April to September, when it has
its greatest development, strong, steady northeast
trade winds prevail over the southern part of the
cruise area. The mean northern limit of the
northeast trades extends to 33 N. latitude on
165 W. during July and August and to 36 N.
on 141°W. during August (U.S.N.H.O. 1401).
In the northern part of the cruise area there
is normally little or no wind because of the
great extent of the center of the high.
During the winter months, October
to March, when the high is weak the Aleutian
Low is the predominant climatic feature of the
North Pacific. In this period the mean northern
limit of the northeast trade wind belt is much
farther south, and the trade winds have lower
velocities and greater variation in direction
than during the summer months. Its most
southern position is between 23 N. and 24 N.
latitude during November, February, and March
on 165 W. longitude, and at the same latitudes
during November on 141 W. longitude (U.S.N.
H. O. 1401). In the northern part of the area
the prevailing winds are westerly because of
cyclonic circulation around the Aleutian Low
and anticyclonic circulation around the high .
The mean position of the southern boundary of
the westerlies is farthest south during January
and February, when it is at approximately
30°N., from 165°W. to 155°W. , and extends
northeastwardly to approximately 34 N. on
141 W. longitude. The limits of westerlies
are not as meaningful as those of the north-
east trades because of the great variability in
the paths and intensities of the lows that sweep
across the North Pacific.
normal charts. A composite of the major fea-
tures of these charts is shown in figures 2
through 4.
Stations 1 through 28 were occupied
January 12 to 31, during which time the mean
surface pressure was very differ ent from normal.
The semi-permanent high, as indicated by the
cell of greater than 1, 020-mb. pressure (fig, 2),
was much smaller than normal and centered
slightly east of its normal position. The Aleutian
Low was much weaker and more diffuse than
normal; it actually consisted of four small cells,
none of which attained the usual depth of less
than 1,000 mb. These conditions are indicative
of a period of relatively weak zonal westerlies
whose limits extend farther south than normal.
This is shown in figure 2 by the restricted
westerly extent of the approximate limits of the
westerlies and trades and the southerly shift of
the limits relative to the mean position. The
weakness of the zonal circulation is also shown
by the differences in the paths of the lows which
had their origin in the vicinity of Japan and the
large number of lows that originated in mid-
ocean. The effects of the southerly shift in the
westerlies and the large number of lows that
originated in mid-ocean are shown by the pre-
dominance of westerly winds (fig. 5) and the
number of fronts (fig. 6) that were encountered
alone and between the transects on 165 W. and
160 W.
During the winter months another
source of storms that affect the area covered
by Hugh M. Smith cruise 25 is the subtropical
cyclones which frequently develop near the
Hawaiian Islands south of the main stream of
the polar westerlies. These storms, locally
known as Kona storms (Simpson 1952), form
as waves in quasi-stationary cold fronts and,
because of their proximity to the Eastern North
Pacific High, usually develop slowly or die
without becoming very intense. However, when
they form as a new or secondary front associ-
ated with a frontal system farther north, they
are vigorous and cause high winds and heavy
rainfall.
The meteorological conditions
during any given period deviate considerably
from the average conditions described above.
The manner and amount of the deviation and
its effect on the actual conditions encountered
is of importance when considering oceanogra-
phic data. Therefore, the mean monthly sea
level pressure charts (furnished by the U.S.W.
B. ) and the daily weather charts (prepared by
the U.S.W.B. , Honolulu, T. H. ) for January
through March 1954 were compared to the
The general features of the mean sea
level pressure chart for February, the period
during which stations 29 through 63 were occu-
pied, were similar to the normal chart in most
respects (fig. 3). The Aleutian Low was about
normal in intensity and centered only slightly
southeast of its usual position, indicating that the
storms that originated along the Asiatic coast
were following their usual pattern. The eastern
North Pacific High was displaced slightly north-
east of its mean position and was slightly less
intense than usual. The latter condition resulted
in a 3- to 4-degree southerly displacement of the
northern limit of the northeast trade wind belt.
The most marked departure from normal was
the trough which occurred in the area west of the
Hawaiian Islands; this trough was the source of
the storms which produced the high winds and
fronts encountered by the Smith during February
(figs. 5 and 6).
Of the three months covered by the
cruise period, the mean surface pressure chart
for March 1954 (stations 64 through 89 were oc-
cupied between March 1 and 16) departed most
radically from normal (fig. 4). The center of the
Aleutian Low was about normal in position and
depth but was much smaller in area. The
Eastern North Pacific High was centered 500
to 600 miles northwest of, and was equal in
area and intensity to, the normal cells for
July and August. Inspection of the daily wea-
ther maps showed that this was the result of a
series of unusually intense (up to 1,047 mb. )
slow-moving highs which began to appear dur-
ing the last week of February and continued
to occur during the first three weeks of March.
As a result of this unusual pressure distribu-
tion, the northern limit of the northeast trades
was at about the same position as the normal
southern limit of the westerlies. The northerly
migration of the trade wind belt is also shown
by the winds observed during the cruise (fig.
5). The winds were almost entirely easterly
after station 54, which was occupied on Febru-
ary 23. The only exceptions were shifts of
short duration which occurred when fronts
passed over the vessel. As during February,
all of the fronts were generated by the lows
which formed in the Hawaiian Islands area
(fig. 6).
CURRENTS
Geopotential Anomalies (Dynamic Heights)
and Geostrophic Currents
Since the discussion of the various
fields of an ocean area is more understandable
when the general character of the flow pattern
has been established, the geopotential anoma-
lies and the dynamic topography and geostrophic
currents will be discussed first. The geopo-
tential anomalies in dynamic meters of the
standard isobaric levels relative to the 1, 000-
decibar surface for each north-south transect
are shown in figures 7-16, and the dynamic
topography of the 0-, 100-, 200-, 400-, and
600-decibar (m. ) surfaces are shown in figures
17-21.
Before discussing the circulation
pattern depicted by these plots, a review of
the assumptions made and procedures used
in their construction is in order. In addition
to the assumption that the 1, 000-decibar sur-
face is the level of no motion, it is assumed
that the cross-sections and contours represent
a synoptic picture, although the time interval
between the first and last station was 2 months.
The curves were drawn to fit the observed data,
and in a few cases, such as the trough in the
o , o
upper 100 meters between 25 and 26 N. lati-
tude on 165 W. longitude, features have been
drawn in from differences in density indicated
by the bathythermograph temperatures. This
procedure gives a more confused current
pattern than the usual smoothed curves, but it
is probably much closer to the actual conditions.
At stations 31 and 89 and at stations 55 and 85,
which were less than 60 miles apart but were
occupied 17 to 20 days apart, the heights and
positions were averaged.
The dynamic topography of the sea
surface, figure 17, shows that the general flow,
except for the area just north of the Hawaiian
Islands, is in an east-southeasterly direction.
A number of both cyclonic and anticyclonic eddies
are superimposed on this flow, the greatest num-
ber and most intense eddies occurring in the
northeastern part of the area. The concentration
r o
is well to the east of 155 W. longitude, where
the spacing of the transects was reduced from 5
degrees to 2 degrees of longitude, so they cannot
be merely attributed to the increase in the station
concentration. Neither can they be attributed to
local winds or internal waves since the largest
and most intense eddies, e.g., the large anti-
cyclonic eddy centered at station 66, were not
associated with storm passages and extended over
two or more stations or transects. In the area
just north of the Hawaiian Islands a narrow ridge
of greater than 1.9 dynamic meters occurs. It
o
extends as far east as 155 W. longitude and cor-
responds very closely to the February-March
position of the center of the Subtropical Converg-
ence.!' indicated on the German Hydrographic
Office (prepared by Schott) (Deutsche Seewarte
1942) current charts.
The principal changes in the dynamic
topography with depth (figs. 17-21) are the grad-
ual northward shift of the ridge which delineates
the transition from eastward to westward flow
and the broadening of the ridge with depth. In the
western part of the area the center of the ridge
shifts from just north of the Hawaiian Islands at
o
the surface to approximately 30 N. on the 600-
decibar surface. To the east it is apparently
south of the area at the surface and shifts rapidly
to the north below the 100-decibar surface so that
it lies within the area as far east as 147 W. on
the 400-decibar surface. A further shift to the
north is indicated on the 600-decibar surface, but
the two large anticyclonic eddies break the ridge
into two parts which correspond to the "Y" shape
of the Subtropical Convergence shown in the
German Hydrographic Office current chart
(Deutsche Seewarte 1942) and to the lobations
which occur in the dynamic topography of the
Carnegie data (Sverdrup et al. 1945, fig. 246).
— "Subtropical Convergence" refers to the
zone of convergence between the easterly flowing
water to the north and the westerly flowing water
to the south.
The persistence of these anticyclonic eddies
and a large percentage of the other eddies
down to the 400-, 600-, and even to the 800-
decibar surfaces, as shown by the cross sec-
tions, is further indication that they are part
of the general circulation and not due to local
or transient phenomenon such as wind shifts
and internal waves.
A comparison of the dynamic
heights of the stations which were occupied
close together in space but at widely different
times demonstrates that the assumption of
steady state for the cruise period gives a re-
alistic concept of the general circulation. The
heights of all surfaces at station 85 were lower
than those of station 55, which was occupied
only 2 miles away 17 days earlier. The cross
sections show, however, that the use of the
heights of either, instead of the average values,
would have merely increased (using station 85)
or decreased (using station 55) the velocities
around the south side of the anticyclonic eddy.
Figure 9 also shows that although the difference
in dynamic heights between stations 31 and 89,
which were occupied 33 miles apart in space
and 34 days in time, was as much as 0. 145 dy-
namic meters (at the surface), the topography
would have been basically the same if either
had been used instead of the average.
The geostrophic current velocities
indicated by the spacing of the dynamic height
contours show that the flow was very weak even
in the well-developed eddies. The maximum
velocities at the surface occur in the three
eddies centered on 145 W. and are only about
0.4 knot (20 cm. /sec. ). The maximum velo-
city in the general zonal (easterly) flow at the
surface is about 0. 2 knot (10 cm. /sec. ). How-
ever, velocities of this magnitude only occur
in narrow bands and the average velocity would
be more in the order of 0. 1 knot (5 cm. /sec, )
or less. On the subsurface levels the velocities
fall off rapidly below 100 meters. The maxi-
mum velocities of the general zonal flow have
decreased to less than 0. 1 knot over the entire
area at the 200-decibar surface, and in the
eddies they are less than 0. 2 knot at 200
decibars and less than 0. 1 knot at 400 decibars .
On the 600-decibar surface the velocities are
less than 0. 02 knot (1 cm. /sec. ) in the general
cyclonic flow through the area and have a maxi-
mum of between 0. 04 and 0. 06 knots (2-3 cm. /
sec. ) in the remnants of the two anticyclonic
eddies on 145 W, These values are well be-
low the limits of accuracy to be expected from
the dynamic topography and show that the use
of a surface deeper than 1,000 decibars, such
as the 2, 500-decibar surface used in the
Carnegie Report (Sverdrup et al. 1944-1945), as
the reference level would not have made an ap-
preciable difference in the dynamic topography
of the upper levels.
Geomagnetic Electrokinetograph Currents
Current measurements at 30-mile
intervals were made with the Geomagnetic
Electrokinetograph (von Arx 1950) during the
second part of Smith cruise 25. The k-factor
was taken as unity, and correction was made for
the droop of the electrodes following procedures
outlined by Knauss (personal communication,
see McGary 1955). Figure 22 gives the results
together with the dynamic topography of the sea
surface with respect to the 1 , 000-decibar level.
It is immediately evident that the
GEK is measuring what may be considered a dif-
ferent part of the "spectrum" of water movement
than that indicated by dynamic computations; the
results are extremely variable in direction and
attain considerably greater magnitudes than the
geostrophic currents. Barnes and Paquette
(1954) describe a very similar situation off the
coast of Washington; the net (geostrophic) circu-
lation there is also relatively slow and motions
with tidal or inertial periods dominate the indi-
vidual GEK measurements. They found that
calculating the data as 48-hour running means
removed most of these short-period variations,
but the results seemed to agree more with the
local winds than with the indicated geostrophic
current. They concluded that the instrument was
measuring real, transient, wind-driven currents,
which are integrated into the longer-term net
flow indicated by the distribution of mass.
Mr. JosephReid at Scripps Institution
of Oceanography (personal communication) found
that simple averaging of the GEK currents by
calendar days seemed to remove most of the
short-term variations from measurements taken
off the coast of California, and the averaged re-
sults indeed show excellent agreement with the
geostrophic currents. Reid subsequently averaged
the Smith 25 data but the results show little agree-
ment with the dynamic topography of the surface
relative to the 1, 000-decibar level (fig. 23) .
Comparison of the GEK currents with
the local winds (fig. 5) shows no obvious relation-
ship. These results are not surprising, consider-
ing the complex nature of the geostrophic currents
in the area and the large variations in the wind,
which during much of the time was directed
against the geostrophic surface current.
While we may feel certain from
previous work that the GEK is giving an in-
dication of real water motions, these motions
are apparently largely of a transient or inertial
character and are difficult to relate meaning-
fully to other data observed on the cruise.
DISTRIBUTION OF PROPERTIES
Temperature
The temperature cross sections
(figs. 24-33) were constructed from bathyther-
mograph observations taken at approximately
30-mile intervals. The plots of the surface
temperatures above each cross section repre-
sent "bucket" temperatures from BT stations
supplemented by reference to recording ther-
mograph traces. These north-south profiles
were then used to construct the horizontal plot
of the surface temperature (fig. 34).
The surface temperature plot
depicts only the gross features of the tempera-
ture field. Thermograph records (see fig. 35
for an example) show that the general decrease
in temperature from south to north occurred in
a series of steplike drops. These drops were
usually less than 1 F. , but occasionally were
as large as 4 F. Frequently they occurred so
rapidly that they appear as vertical lines on
the thermograph traces. The thermograph
records also show a large number of fluctua-
tions superimposed on the general trend. These
were generally of less than 1 F. but occasion-
ally attained an amplitude of 3. 5 F. A careful
check of the bucket temperatures against the
thermograph showed these variations were not
the result of temperature changes in the engine-
cooling water intake, where the sensitive unit
of the thermograph was located, except when
the engines were stopped. The stopping of the
engines produced such distinct patterns that
there was no possibility of confusing them with
the fluctuations in the surface temperature.
The fluctuations in the surface temperature
varied in horizontal extent from those which
were so small that they could barely be dis-
tinguished from the oscillations caused by the
roll and vibration of the vessel to the large
ones that embraced two or more BT casts,
and which are incorporated in the temperature
profiles.
When the variability of the winds,
the season of the year, the geographical position
of the area, and the geostrophic currents are
considered, the complexity of the temperature
field is quite comprehensible. Similar varia-
tions observed in other areas (Saelen 1952,
Mackintosh 1946) seem to be associated withone
or more of the following phenomena: large
horizontal velocity gradients (shear zones), up-
welling, convergence, and winter conditions in
the middle and higher latitudes.
The general configurations of the
surface isotherms (fig. 34) were consistent with
the geostrophic currents (fig. 17). The isotherms
which are continuous from east to west are rough-
ly parallel to the dynamic height contours. The
tonguelike pattern of the isotherms in the anti-
cyclonic eddies centered on 145 W. longitude is
characteristic of this type of circulation
(Sverdrup and Fleming 1941). Many of the warm
and cold cells occurred in areas of relatively
large horizontal temperature gradients. For
example, the cold cell of less than 62 F. cen-
tered at 32 30'N. on 160 W. is on the northern
side of an area having relatively high velocities
and where the curvature of the dynamic height
contours is cyclonic.
An example of the effect of local
wind mixing is illustrated by the tongue of less
than71°F. at approximately 23°N. , 163°W. The
weather data (figs. 5 and 6) show that two cold
fronts with winds of over 30 knots had passed
over the area in rapid succession just before the
observations were made.
Charts of mean monthly surface
temperatures (U. S. Navy Hydrographic Office
1944, Robinson 1951) show a large seasonal
shift of the mean position of the isotherms in the
cruise area. For example, the mean position of
° o
the 65 F. isotherm on 150 W. shifts from
42°15'N. in August to 30°15'N. in March. This
indicates either that normal winter cooling, be-
cause of differences between the air and sea
temperature, continues through March or that
the flow through or into the area has a sufficiently
large southerly component to offset the heating
due to increased radiation.
The air temperatures observed at
each bathythermograph station were plotted on
the temperature cross sections (figs. 24-33) to
ascertain whether there was any consistent dif-
ference between the air and sea temperatures.
The plots show that the air over the southern part
of the area was cooler than the water for the
most part but that changes in the air circulation
frequently reversed the gradient. The only area
where the air was consistently warmer than the
water was in the extreme north and in the area
between 149 W. and 153 W. , where the geostro-
phic flow (fig. 17) was southeasterly. This tem-
perature difference indicates that at least some
of the small surface temperature changes were
the result of local heating or cooling.
The dotted lines on the horizontal
plot of surface temperature (fig. 34) show the
0,0,0 o
mean position of the 70 , 65 , 60 , and 55 F.
isotherms. They have been interpolated from
the U.S.N.H. O. Surface Temperature Atlas
(1944) to correspond to the approximate time
of transit on each leg, thus permitting a
comparison of the temperature encountered on
the cruise with mean conditions. The greatest
and most consistent difference from normal
occurs west of 155 W. , where all the isotherms
are farther north than normal. East of 155 W.
the 55 F. isotherm, which is farther south
than usual, is the only one that is consistently
different.
The most significant features of
the temperature field were several abrupt
meridional changes of 2 -4 F. They are
shown by the large gradients on the surface
temperature plot (fig. 34) and on the surface
temperature profiles (figs. 24-33). The
changes were sharpest in the western part of
the area, where they coincided with steep
gradients in the dynamic topography. The
most striking example occurred on the 160 W.
transect, where the thermograph record (fig.
35) shows a rise (vessel course was 180 T. )
from 58 F. to 60 F. in about 4 minutes
followed by a series of more gradual rises to
almost 63 F. over the following 2 hours and
45 minutes. At the 8. 5-knot average speed of
o
the Smith this represents a rise of almost 5 F.
in 25 miles. According to Mackintosh (1946)
such abrupt changes in temperature are
characteristic of areas of convergence between
water masses.
Major changes in the vertical
temperature structure were frequently associ-
ated with surface temperature discontinuities.
At many, the south to north shallowing of the
isotherms (see figs. 24-33) increased sharply.
The increase in slope affected all of the iso-
therms instead of only the shallow ones, as in
the case of changes of slope which are attribu-
ted to internal waves.
North of the discontinuities which
occurred at temperatures of 60 F. or less, the
homogeneous surface layer was almost entirely
missing, the bathythermograph trace showing
either a gradual decrease to 900 feet or a
series of small steplike changes. Again, the
phenomenon was most pronounced in the west-
ern part of the area, where the flow was basic-
ally zonal. The BT traces from the stations on
160 W. have been reproduced in figure 36 to
illustrate the change in their structure from
south to north. Both the abrupt change in slope
of the isotherms and the absence of a homogene-
ous surface layer are characteristic of the zones
where mixing and sinking take place at the con-
vergence between two water types (Sverdrup and
Fleming 1941).
Density
The internal distribution of density
(sigma-t) in the ocean reflects both the field of
motion and the modifying processes occurring
at the surface. The effect of motion is seen in
the distributions of mass giving rise to the
pressure gradients associated with horizontal
currents; by this association an examination of
the sigma-t plots can yield a qualitative descrip-
tion of the major features of the circulation. The
surface modifying processes directly affect a
relatively thin upper layer, the "surface layer, "
keeping the layer nearly vertically homogeneous,
and causing large time and space variations in
its properties.
Turning first to this surface layer
(fig. 37), we can see the general northward in-
crease in density associated with the decrease in
temperature. The meridional change in density
in the area of our sections is less in the east;
this is because water of lower salinity (more
northern origin) is present farther to the south
in the eastern part of the region. The greater
northward decrease in salinity here tends to off-
set the decreasing temperature in determining
the density of the surface water.
The sections (figs. 38-47) show the
general northward thinning of the surface layer
connected with the net easterly flow of the North
Pacific Current. The surface layer becomes ex-
tremely shallow at the northern end of the eastern
sections, another indication that this region is
influenced by more northerly conditions than the
western part of the area. The local irregularities
and inversions to be expected in this area of
rapidly changing conditions and slow water motion
are evident on the sections.
The relatively sharp density gradient
of the thermocline lies directly below the surface
layer. The sigma-t surfaces show a net north-
ward decrease in depth, again an indication of the
easterly North Pacific Current. At the depths of
the surface layer and upper thermocline the
southern boundary of this current is at or beyond
the southern limit of our sections, for there is
no change in the slope of the upper thermocline
to indicate a transition to the westerly flow of the
North Equatorial Current. The large irregularities
in the density structure associated with the
eddies described previously may be seen in
the sections at the longitudes of the eddies.
The depths of two sigma-t surfaces
associated with the region of the thermocline
are shown on horizontal plots (figs. 48 and 49);
the shallower, sigma-t = 25.2, comes to the
sea surface within the area of the cruise.
While sea surface influences determine the
northward extent of this layer, both surfaces
otherwise reflect the circulation indicated by
theplots of dynamic topography at these depths.
The complex region of eddies is seen in the
eastern part of the area, while the northward
shift with depth of the boundary of the westerly
North Equatorial Current is noticeable in the
southwest corner of the area on the deeper
(sigma-t = 26. 0) surface. In general, there
is more detail of the circulation evident on the
sigma-t surfaces than in the smoothed dynamic
topographies.
The deeper portions of the
meridional sections (figs. 38-47) show a north-
ward 9hift with increasing depth of the trough
in the isopleths marking the transition from
easterly to westerly zonal flow. The topography
of the sigma-t = 26. 8 surface (fig. 50), which
corresponds closely to the position of the deep
layer of minimum salinity of northern origin,
again closely resembles the indicated geostro-
phic circulation at similar depths; the current
is slow, turning broadly back toward the west,
with southerly flow through a large part of the
area.
Salinity
In the surface layer (fig. 51) the
major features are the region of salinity maxi-
mum in the latitudes of the southern edge of
the cruise area and the rapid decrease in sali-
nity northward from this region, particularly
in the east. The maximum is formed by the
excess of evaporation over precipitation in
these latitudes and is distributed in a broad
zonal band by the currents (Jacobs 1951). The
water to the north of the cruise area is partly
of northern origin and is low in salinity; be-
tween is the area of transition characterized
by a large meridional salinity gradient. This
gradient is not smooth, but reflects the irre-
gularities (such as the eddies) in the circulation.
Below the surface layer a deep
salinity minimum (400-600 m.) is evident on
all the sections (figs. 52-61), with a second
shallow minimum appearing in the northeast
part of the area. The deep minimum,
characteristic of the greater part of the sub-
tropical and temperate Pacific, is probably
maintained by water formed in the northwest, in
the convergent region between the Kuroshio Ex-
tension and the Oyashio (Sverdrup et al. 1942).
The shallow minimum occurring in
the northeastern part of the cruise area seems
to be formed by surface convergence. Figures
62 to 64 give the depth, salinity, and sigma-t at
the level of this minimum, and show its southern-
most extent. The flow is mostly parallel to the
isohalines, and the depths indicate that part of
the region of origin is close to or at the northern
edge of the cruise area. The widely varying
values of sigma-t suggest that considerable non-
isentropic mixing is occurring at these relatively
shallow depths, and also doubtless reflect ir-
regularities in the formation of the minimum at
the surface. This shallow minimum was men-
tioned by Sverdrup et al. (1942, fig. 202 and p.
723) and is apparently characteristic of this area.
The waters of the upper minimum turn toward the
south with the general circulation. More com-
plete station coverage, especially to the east of
the Smith cruise 25 area, is needed to describe
the formation and distribution of this minimum.
The salinity distribution is shown on
the three sigma-t surfaces discussed in the sec-
tion on density (figs. 65-67). On the two shallower
surfaces the isohalines very roughly parallel the
geostrophic flow at these depths, with irregulari-
ties particularly noticeable in the eddy region.
The shallowest surface, sigma-t = 25.2, is still
somewhat within the direct influence of the sea
surface and shows the greatest variations in
salinity. On the intermediate surface, sigma-t
= 26. 0, the southward extension of low salinity in
the east is connected with the intrusion of the
upper salinity minimum, which is centered
slightly above this sigma-t surface (see fig. 64).
On the deep surface, sigma-t = 26.8,
very nearly coinciding with the center of the deep
salinity minimum, the 34.00 /oo isohaline lies
across the flow. The flow here is very weak,
however, and the salinity changes are small; the
downstream salinity increase is the result of
vertical mixing and diffusion.
Temperature -Salinity Relationships
Although it is not within the scope or
intent of this report to enter into a detailed dis-
cussion of the temperature-salinity relationships
from the standpoint of the origin of the water, they
do help clarify the circulation. The curves for the
160°W., 155°W. , 147°W., andl41°W. transects
have been combined in single plots (figs. 68-71)
in order to depict the salient features of the
latitudinal and longitudinal changes. The limit-
ing T-S curves of the three water masses into
which the waters of the North Pacific are
commonly divided (Sverdrup et al. 1942) are
included in each plot for comparative purposes.
In the western part of the area
(160 W.), the curves lie along the lower sali-
nity limit of the Western North Pacific Central
Water (fig. 68), except in the upper 100-200 m.
and at temperatures of less than 8 C. at sta-
tions 3 and 28. At 8 C. , the temperature at
which the curves delineating the lower salinity
limits of the Eastern Central Pacific Water
and the Western North Pacific Water intersect,
stations 3 and 28 depart abruptly from the
other curves and follow the Eastern North
Pacific Central Water.
At the shallower depths along
160 W. the interval between stations 22 and 23
(fig. 68) is the transition zone between the
southern stations which have a salinity maxi-
mum at or near the surface and the northern
stations which have a minimum at or near the
surface. The shallow maximum at the southern
stations is characteristic of a region where
evaporation produces an increase in salinity at
the surface, causing the water to sink and
spread out at an intermediate depth. Instead
of showing a gradual shift toward lower tem-
peratures and salinities, the surface portion
of the curves for the northern stations show an
uneven change in temperature-salinity relation-
ships. The small changes (e.g., sta. 17-18)
correspond to and account for the relatively
level zones in the dynamic heights. The large
changes (e. g. , sta. 18- 19) represent transitions
between waters of slightly different type and
correspond to zones of relatively large geo-
strophic currents. The irregular shift between
the curves leads to the conclusion that the
decreased temperature and salinity in the
surface layers are the result of masses of
water of more northerly origin, that is, water
containing greater percentages of Subarctic
Water, being driven into the area by the winter
westerlies instead of being simply the result of
latitudinal changes of temperature and rate of
precipitation or evaporation.
Moving east to 155°W. (fig. 69),
the curves form a less compact band but still
lie just below the lower salinity limit of the
Western North Pacific Central Water, except
o
at temperatures of less than 7 C. , and in the
surface water (upper 100-200 m. ). At tem-
peratures of less than 7 C. the curves do not
follow the standard curves as closely as they
did on 160 W. The discontinuity between the twoi
southern stations (31 and 32) and the remainder
of the stations is not as pronounced as on 160 W. ,
the maximum difference amounting to only
0. 1 /oo. In the surface waters the abrupt change
in the shape and position of the curves indicating
the transition from the southern stations having
a salinity maximum at or near the surface and
the northern stations with a minimum at the sur-
face occurs between stations 37 and 38. Again
the sharp changes between the two groups of
stations and within the groups correspond t o
zones of relatively large geostrophic current
velocities.
The 147°W. transect (fig. 70)
intersects the complex eddy system in the north-
east part of the area, so the changes in the
temperature -salinity relationships reflect the
complex circulation around the eddies as well as
the expected changes with latitude. Except for
station 58, the curves along 147 W. form a com-
o „o
pact band between 7 and 10 C. just below the
lower salinity limits of the Western North Pacific
Central Water. For the most part below 7 C. the
salinity shows a gradual decrease at a given
temperature from south to north with occasional
slight reversals. As can be seen from the plot,
the difference between the curve for station 82,
the southernmost station, and those of the adjoin-
ing stations was the only one consistent enough to
indicate a change in water mass.
At temperatures greater than 10 C.
along 147 W. there is a sharp shift in temperature-
salinity relationships between southern and
northern stations, the change occurring between
stations 55 and 56. Considering the southern
stations, the only significant change is a shift be-
tween 17 C. and 10 C. from the lower salinity
limit of the Eastern North Pacific Central Water
to just below the lower limit of the Western North
Pacific Central Water. The reason for the shift
and the correspondence of the curves to Eastern
North Pacific Central Water above 10 C. is ap-
parent from the slight secondary salinity minimum
which occurs at about 14 C. at stations 84, 85,
and 55. This indicates that there is a subsurface
influx of less saline water centered at about the
25. 6 sigma-t surface. The extent and possible
origin of the minimum is discussed in the section
on salinity.
Because of the confused circulation
resulting from the eddies there are no systematic
shifts among the surface portions of the T-S
o
curves at the northern stations on 147 W. For
example, the salinities at all temperatures at
station 58 were less than those at 59 and less
than those at 60 at temperatures below 1 1 C.
The most pronounced difference between these
northern stations and those from farther west
is the presence of the salinity minimum at 100
to 230 meters (see fig. 62) instead of at the
surface.
On 141°W. (fig. 71), the most
easterly transect, the curves had two common
features: all, except 79, formed a compact
band between 6.5 C. and 8. 5 C. , and all had
a deep and a shallow salinity minimum. As in
the deeper water of the western sections, sali-
nity gradually increased from north to south at
temperatures less than 6.5 C. Again the dif-
ference between the southernmost station,
station 79, and the adjoining station was suffi-
cient to indicate a distinct change in water
mass.
At temperatures greater than
8.5 C. there were three abrupt shifts among
the curves. The most pronounced was between
stations 75 and 76, but there was such a large
space and time interval between these stations
because of heavy weather that the sharpness
and position of the break is suspect. South of
station 76 the curves lie just below the mini-
mum of Eastern North Pacific Central Water,
a slight decrease in salinity from the southern
stations of 147 W. North of station 75 the in-
flux of Subarctic Water is again apparent from
the large differences among the curves. All
of these, except between stations 72 and 73,
correspond to changes in the dynamic topogra-
phy along the transect. If the contours of the
dynamic topography at the surface are traced
to the west (upstream), the more northerly
origin of the surface water at station 72 is
obvious.
Dissolved Oxygen
The dissolved oxygen content of the
ocean provides an additional tool for tracing
the origin and movements of water masses.
It is absorbed at the sea surface in amounts
dependent upon the salinity and temperature of
the water and the pressure, which is usually
considered to be standard (1,013 mb. ), and
moisture content of the air, which is usually
neglected. Below the euphotic zone, biological
processes lead to the consumption of oxygen so
that the processes of diffusion and advection
must be such that, if the oxygen content of the
deeper layers remains constant, they lead to
a replenishment that exactly balances the con-
sumption (Seiwell 1937).
The longitudinal profiles of
dissolved oxygen are shown in figures 72-81,
the horizontal plot at 10 m. in figure 82, and the
distribution on the 26. 8 sigma-t surface in figure
83. The isopleths of percentage saturation have
been included on some of the plots to show the
degree of depletion of the subsurface oxygen and
hence the implied direction of movement, if the
consumption is assumed to be independent of the
oxygen content until it is nearly depleted (ZoBell
1940). The saturation values used to compute
the percentages were taken from Fox's tables
(Harvey 1928), which were computed on the as-
sumption that sometime during the past the water
had been at the surface in contact with dry air at
normal pressure (1013.3 mb. ) at the in situ
temperature and salinity.
The 10-m. samples were used to
depict the dissolved oxygen content at the surface
because the surface Nansen bottle was frequently
in the turbulent area around the hull when the
vessel was rolling heavily. The distribution of
dissolved oxygen on the 10-m. surface (fig. 82)
followed the pattern indicated by the temperature
and salinity fields. The highest oxygen values
were at the northern edge of the area where the
lowest temperatures and salinities were observed,
and the least oxygen in the area just north of the
Hawaiian Islands, where the highest temperatures
and salinities were observed.
The profiles of dissolved oxygen (figs.
72-81) show that the pattern of the vertical dis-
tribution is basically the same over the entire
area. It consists of a surface layer of almost
uniform content, a layer of small, variable nega-
tive gradient, a layer of large and almost uniform
negative gradient, and in a few of the sections a
layer in which the negative gradient decreases
and changes to a positive gradient. The latter
does not occur in all of the sections, since the
oxygen minimum was below 1, 000 m. in a large
number of cases (see observed data).
As expected, at each station the
surface layer of almost uniform dissolved oxygen
content corresponded to the layer of uniform den-
sity resulting from wind and advective mixing.
In almost all cases the values in this layer were
within -0.05 ml. /I. of the 10-m. value.
Instead of a rapid decrease in the
dissolved oxygen content just below the surface
layer, such as occurred in the temperature and
density fields, there was a layer of small and
variable negative gradient between the surface
and the band of large negative gradient. The
cross sections (figs. 72-81) show that the
4. 5-ml. /I. isopleth, which varies between 300-
550 m. in depth, approximates its lower limit.
It is deepest between 30 and 32 N. or at about
10
the same latitude as the ridge in the dynamic
topography of the deeper isobaric surfaces.
In the southern part of the area there are a
number of inversions, such as the cell of
greater than 5. 5 ml. /I. which is centered at
150 m. at 31°00'N. on 147°W. Further indi-
cations of the variability of either the oxygen
consumption or the mixing in this layer are
shown by the lack of similarity between the
oxygen profiles and the sigma-t profiles (figs.
38-47) and the abrupt departure of the percent-
age of saturation isopleths on 165 W. (fig. 72)
from the oxygen isopleths in the southern part
of the area.
The layer having an almost uniform
bat large negative gradient, up to 2. 0 ml. /I.
per 100 m. , extends down to the 1.5-ml. /I.
o o
isopleth on 160 and 165 W. and to the
1. 0-ml. /I. isopleth over the remainder of the
area. The sigma-t (figs. 38-47) and percent-
age of saturation isopleths are basically paral-
lel to those of dissolved oxygen in this zone,
indicating that the rate of consumption and re-
plenishment via diffusion and lateral mixing
must be in equilibrium. The most interesting
feature of this layer is that it also contains the
deep salinity minimum. The center of the
salinity minimum fluctuates between the 3.0-
and the 4. 0-ml. /I. (02) isolines. This
variation is probably due to the difficulty of
locating the center of the minimum on the sta-
tion because of the small salinity gradients.
The decrease in the dissolved
oxygen gradient below the 1. 0- and 1. 5-ml. /I.
surfaces and its final shift to a positive gradi-
ent resulted in a minimum which, as reported
by Sverdrup et al. (1942, p. 729), was about
400-500 m. below the deep salinity minimum.
Because of the great thickness of the band of
water with low oxygen content, the large spa-
cing of the bottles at the depth at which it oc-
curred, and the fact that it was not reached by
the 1 , 000-m. casts on the northern part of the
two westernmost transects (stations 7-25), no
attempt has been made to contour it. However,
sufficient data were available to show that a
line drawn through the minimum between sta-
tions 7 and 75 would approximate the 1, 000-m.
contour. The deeper values were to the north-
west and the shallower to the southeast, indi-
cating that the depth of the minimum tended to
decrease from northwest to southeast.
The isopleths of the oxygen content
at the minimum had a radically different
pattern from its depth contours. The lowest
values formed a tongue of less than 0.4 ml. /I.
which entered the area between stations 62
and 75 and extended in a west-southwest direction
as far as stations 54, 47, and 48. The highest
minimal values formed a tongue of greater than
1.0 ml. /I. which entered the area between sta-
tions 4 and 5 and extended eastward as far as
station 28.
The only sigma-t surface on which
there was a significant difference between the
sigma-t and the dissolved oxygen contours was
the 26.8 surface (fig. 83). On this surface the
oxygen decreases in the direction of flow, indi-
cating that oxygen is. either being consumed by
biological activity or depleted by diffusion. Evi-
dence of the latter is shown by the decrease along
the 600-m. contour from 3.01 ml. /I. at station
47 to 2.06 ml. /I. at station 28, while in contrast
the oxygen minimum increases from 0. 37 ml. /I.
to 1.02 ml. /I.
Dissolved Inorganic Phosphate
The primary purpose of making
dissolved inorganic phosphate determinations was
to determine if there had been divergence or con-
vective mixing in any part of the area of sufficient
magnitude to bring nutrients to the surface layer
in excess of the utilization by biological activity.
The secondary purpose was to map the vertical
distribution of the nutrients. The surface values
are shown in figure 84 and the cross sections,
except for the 155 W. transect, in figures 85-93.
The profile for 155 W. was omitted because the
Automatic Servo-Operated Photometer was not
functioning properly between stations 30 and 38,
and the resulting data were too erratic to be
considered reliable.
Although most of the surface values
(fig. 84) were near or below the lower limit of
accuracy (about 0. 4 ug. at. /I. ) of the molybdenum-
blue method of determining dissolved inorganic
phosphate (Wooster and Rakestraw 1951), the
consistency of the distribution with the other
fields indicates that they portray a valid picture
of the distribution. As expected from the Carne-
gie data (Sverdrup et al. 1945), the surface phos-
phate content decreased from north to south on
all sections.
When the surface phosphate distribution
(fig. 84) is compared to the temperature and
salinity fields, it is evident that the southerly
shift from summer conditions is not entirely the
result of convective mixing induced by winter
cooling and increased wind mixing. In the north-
western part of the area, where the southerly
shift of the westerlies is normally the greatest,
the surface phosphates were the largest.
11
However, instead of the deep, homogeneous
surface layer that should result from increased
wind mixing and convective overturn, there was
virtually none (figs. 24-33 and 36) in this area,
indicating that some other mixing forces must
be involved.
Comparison with the temperature,
salinity, and dynamic topography shows that
the large horizontal gradients in surface PO4
correspond to sharp changes in these fields.
Again using the 160 W. section as an example,
the phosphate increased from 0. 17 ug. at. /I.
at station 21 to 0.40 ug. at. /I. at station 20,
and from 0. 36 ug. at. /I. at station 19 to 0. 55
Ug. at. /I. at station 18, corresponding to ab-
rupt changes in surface temperature (figs.
24-34), distinct shifts in the T-S curves (fig.
68), and zones of relatively large geostrophic
currents (fig. 17). In addition, the temperature-
salinity relationships (figs. 68-71) show that
the surface waters of the northwest part of the
area contain less water of northern origin than
the water at the same temperatures farther
east. This indicates that mixing as a result
of turbulence in the areas of relatively large
horizontal current shear in the transition zone
between waters of slightly different type
(Sverdrup et al. 1942, p. 472) contributes to
the enrichment of the surface water and ac-
counts for the largest surface phosphate values
being in the northwestern part of the area.
The isolated cell of greater than
0.2 ug. at. /I. centered at about 30 N. on
165 W. (fig. 84) is based on the observations
from a single station. However, it is probably
real since, in addition to the relatively large
horizontal velocity gradients and divergence in
the surface currents indicated by figure 17, the
station was occupied during a period of high
winds (Beaufort force 7) (fig. 5).
In the southeastern part of the area,
the 0. 1 ug. at. /I. contour is drawn as a dotted
line to show that there was little or no phosphate
in the surface waters. Further evidence of
barrenness in this area was the deep blue color
of the water (see table 1).
The vertical distribution of dissolved
inorganic phosphate is shown in figures 85-93.
As expected, its pattern is almost the opposite
to that of the dissolved oxygen. At the surface,
except in the areas of large horizontal velocity
gradient mentioned above, there is a layer in
which the concentration is relatively low and uni-
form. Below this layer the phosphate increases
rapidly and, in general, uniformly with depth to
about the 2. 8 ug. at. /I. isopleth, and the trend
continues until a maximum of between 3. 00 and
3. 86 ug. at. /I. is reached at about the same
depth as the oxygen minimum.
Water Transparency
Whenever the sea and weather
conditions permitted, water color determinations
according to the Forel scale and transparency
observations by means of a Secchi disk (Sverdrup
et al. 1942, p. 82) were made immediately after
the hydrographic cast. Only 13 reliable

DISCUSSION
Many of the similarities and
differences between the circulation pattern and
the distribution of the various chemical and
physical fields observed on this cruise and
those described by previous writers have been
discussed in the description of these fields.
Most of the differences can be attributed to the
fact that many of the previous discussions have
been either based on data taken during summer
months, e.g., Carnegie data (Sverdrup et al.
1945), or have been based on averages from
data taken over a number of years, e. g. ,
(Schott's current chart)(Deutsche Seewarte 1942^
The most comprehensive summary
of the general features of the physical oceano-
graphy of the cruise area was given by Sverdrup
in his discussion of the water masses and cur-
rents of the oceans (Sverdrup et al. 1942,
Sverdrup 1943). According to his charts of the
water masses and mass transport of the North
Pacific (Sverdrup et al. 1942, figures 196 and
205, and chart VII), the cruise covered one of
the most complex areas of the North Pacific,
including the broad transition zone between the
Western and Eastern North Pacific Central
Water masses and the transition zone between
these water masses and the Subarctic Water.
Under average conditions the cruise area
should have included parts of the following
major components of the North Pacific circu-
lation: the North Equatorial Current, the
North Pacific Current, the Subtropical Con-
vergence, the Arctic Convergence or the North
Polar Front, and the Eastern Gyral or Gyre.
The North Equatorial Current is
the name given to the westerly flowing current
in the lower north latitudes of the central
Pacific. The geostrophic currents indicated by
the dynamic topography (fig. 17-21) show only
a small area of westerly flow just north of the
Hawaiian Islands, the northerly limit of which
shifts slightly to the north with depth. Within
the westerly flow, except for the small cell of
>0. 2 (xg. at. /I. of inorganic phosphate at the
surface at station 3 (fig. 23), there is no evi-
dence of mixing, other than normal diffusion,
of sufficient magnitude to cause enrichment of
the euphotic zone (upper 80-100 m. ). Station
3 is just north of Kauai, and the slightly higher
phosphate content of the surface here was
probably the result of the turbulence induced by
the flow around the islands.
The Subtropical Convergence has
already been defined (page 4) as the zone of
convergence between the easterly flowing water
to the north, the North Pacific Current, and the
westerly flowing water to the south, the North
Equatorial Current. The position, northerly
shift, and broadening of the transition zone with
depth have already been pointed out. The rela-
tively large horizontal sigma-t gradients at the
surface (fig. 37) illustrate the rapid poleward
increase in density of the upper layers which is
associated with the Subtropical Convergence
(Sverdrup et al. 1942, p. 140). The occurrence
of the salinity maximum at the surface in the
area (figs. 51 and 52-61) indicates that it is part
of the source of the subsurface salinity maximum
found in the lower latitudes of the central North
Pacific. Thus, it is an area of subsidence and
should be unproductive. This is borne out by the
low phosphate content of the surface waters (figs.
84 and 85-93).
The North Pacific Current is the
name applied to the general eastward flow of
warm water to the east of 160 E. It s e n d s
branches to the south, and normally the greater
part has turned south before reaching 150 W. so
that only a small portion flows south to the east
of the Hawaiian Islands. The similarity of the
T-S curves from the western part of the area to
those of the western North Pacific Central Water
(figs. 68-71) is evidence that the band of south-
easterly flowing water whose northeastern limit
is approximated by the 1. 72-dynamic-meter con-
tour at the surface (fig. 17) is a southern branch
of this North Pacific Current which has penetra-
ted farther east than normal. This was probably
the result of the southeasterly shift of the limits
of the westerlies and trades, which the January
and February 1954 mean sea level pressure
charts indicate was even farther than usual. The
only evidence of enrichment of the surface layers
within the North Pacific Current was at station 8
at 30 N. on 165 W. , where the surface phosphate
values were between 0.4-0.5 (ig. at. /I. Although
this station was located in an area of relatively
large and divergent surface currents, the local
nature of the high phosphate content and the fact
that the station was occupied just after a period
of Beaufort 7 winds lead to the conclusion that it
was a local phenomenon.
When the geostrophic currents are
considered alone, the general easterly flow in the
northern part of the cruise area appears to be a
branch of the North Pacific Current, which
13
continues east along the northern side of the
Eastern Gyre. However, as has already been
pointed out in the discussion of the temperature -
salinity relationships, a series of abrupt shifts
occur in the surface portion of the T-S curves,
showing an intrusion of colder and less saline
water from the north. A complete transition
to Subarctic Water was not made on any of the
transects, so the core of the Aleutian Current,
being defined as an easterly flow of Subarctic
Water, was not reached.
Previous authors have shown
considerable variation in the latitude, extent,
and nature of the eastern portion of the transi-
tion zone between the North Pacific Current
and the Aleutian Current. Merz's chart of the
currents of the Pacific in northern summer
(Wiist 1929) shows it as a line beginning off the
coast of Japan at about 36 N. and extending in
a wide arc through 42 N. , 170 E., to about
35 N. latitude, 160 W. longitude. He applies
the name North Polar Front to the line. Schott
(Deutsche Seewarte 1942) shows the transition
as a line of convergence which corresponds to
Merz's from the coast of Japan to 170 E.,
42 N. It then continues northeast as an indefi-
nite line to 45 N. latitude, 165 W. longitude.
In the area north of the Hawaiian Islands, Schott
indicates the line of divergence shown in figure
17. Sverdrup et al. (1942, figs. 205 and 209A)
show the transition zone as the boundary be-
tween the Subarctic Water and the Eastern and
Western North Pacific Central Water masses.
They portray it as a zone extending in a wide
arc completely across the Pacific. It also
corresponds to Merz's Polar Front to about
180 . It then continues to about40°N., 150°W.,
where it turns southward and parallels the
coast of North America to approximately 20 N.
The differences in interpretation
by the three authors are quite understandable
when the small amount of data and the different
methods used in the analysis of the circulation
are considered. Schott used ship's drift,
Sverdrup largely temperature-salinity rela-
tionships andMerz apparently a combination
of both. However, Merz did not have the
benefit of more recent surveys such as those
of the Carnegie and the Bushnell. Actually,
the major differences among these authors'
interpretations of the cruise area can be rec-
onciled. In the area where Schott shows a
divergence in the surface current, Sverdrup
et al. (1942, fig. 205) indicate a branching or
divergence of the North Pacific Current. Wiist,
in his discussion of Merz's North Polar Front,
states that in the eastern part of the ocean,
although the front has the unstable temperature
characteristics of a convergence in the direction
of flow, it shows mixing of the colder, deeper
waters with the surface water. This would cause
enrichment and cooling of the surface, which are
the two most outstanding characteristics of an
area of divergence.
If it is remembered that in the ocean
an abrupt, discontinuous transition from one type
of water to another is almost never found and
that the line merely indicates that the transition
takes place over a relatively short distance,
Wiist's geographical limits of and description of
the eastern part of the North Polar Front seem
to fit the northwestern part of the cruise area.
The T-S curves show that the incursion of the
Subarctic Water took place in the form of a
series of narrow streams rather than a broadly
moving front. The dynamic topography shows
that the bands of relatively high velocity, which
resemble the multiple currents of the Gulf
Stream described by Fuglister (1951), occurred
in the boundaries between these streams. The
turbulence in these zones of relatively large
horizontal velocity gradient probably cause the
mixing of the deep water with the surface waters
described by Wiist and accounts for the large
horizontal phosphate gradients in these zones
and the occurrence of the highest phosphate
values in the northwest part of the area.
The reported existence of the North
Pacific Gyral, a clockwise gyral centered between
the Hawaiian Islands and the west coast of North
America, is based mainly on the characteristics
of the water and results of current and mass
transport computations (Sverdrup et al. 1942, p.
723). Its center is believed to coincide with the
center of the Eastern North Pacific High, so it
undergoes considerable seasonal migration and
variation in size. Considering the radical shift
that occurred in the mean position of the High be-
btween February and March, it is not surprising
that there was little evidence of a distinct gyral
in the dynamic topography of the eastern part of
the area. However, many of the other character-
istics of the Gyral were present in the southeast-
ern part of the cruise area. The isolated cell of
sigma-t greater than 25.0 at the surface, the
topography of the shallow salinity minimum, and
the close approximation of the T-S curves at the
o o
southern stations on the 147 W. and 141 W. lon-
gitude transects to those of the Eastern North
Pacific Central Water show that it is centered at
about the southernmost of the two anticyclonic
cells on 145 W. longitude. The maximum depths
of up to 200 m. of the top of the thermocline which
occurred just south of the center of this cell il-
lustrate the effect of convergence in the surface
waters. The impoverishment of the southern
14
part of the Gyral is shown by the tongue of
less than 0. 1 ug. at. /I. in the surface plot of
inorganic phosphate, the large Secchi disk
readings, and the blue color of the water.
In conclusion, the only areas in
which there is an apparent source of continuous
mixing which should provide enrichment of the
surface layers are the zones of large horizontal
current shear in the Polar Front. It is inter-
esting to note that the albacore taken by the
J. R. Manning (cruise 19), which was operating
in the area concurrently with the Smith, were
taken at or near these zones (Shomura and
Otsu MS^/. For example, the best days1
catch of 42 albacore (5.4/100 hooks) was made
on the 160 W. transect at 33 58'N. , just south
of the area where the surface temperature rose
from 58 F. to 63 F. in only 25 miles, and in
the area where the first sharp increase in the
surface phosphate occurred.

NOTES ON THE TABULATED DATA,
HMS-25
In every case, any variation from
the standard 13-bottle cast has been noted and
explained. (See explanatory code.)
Where more than one cast was taken
on a station, they are divided in the observed
data by a horizontal line. The cast number is
indicated by a Roman numeral at the left
margin.
Where the duplicate temperature
readings differed by more than 0. 05 below
300 m. , or more than 0.10 above 300 m. ,
and where the duplicate salinity titrations
differed by more than 0. 02 /oo, and where
the duplicate phosphate determinations differed
by more than 0.01 extinction (about 0.05 \ig.
at/1.), both values were plotted on the station
graphs. If one of these values was used in
drawing the curve, it is carried in the data
and the other discarded. If no choice can be
made between them, the value interpolated
from the curve is used. This interpolation is
rare in the salinity values and is indicated
where present; it is common for phosphate,
and not indicated; it did not occur in the tem-
perature values.
Explanatory Code for Tabulated Data
a/ No analysis made for this property, or
analysis faulty and discarded.
b/ Nansen bottle pretripped; no water sample
or temperature.
c/ Individual water sample lost.
d/ Value definitely bad and discarded.
e/ Value seems anomalous, but not positively
out.
f/ Only one titration made due to insufficient
sample.
g/ Duplicate salinity titration values differ
by more than 0.02 /oo but less than 0.07
/oo; value tabulated is interpolated be-
tween the duplicates from the station
curve.
Weather is recorded in the ww
(present weather) code given in the U. S.
Weather Bureau Circular M, eighth edition,
Manual of Marine Meteorological Observations.
Cloud cover is given in tenths of sky covered.
Wind velocity was measured with an anemo-
meter 30 meters above the sea surface. The
direction (given to the nearest 10 ) is that
from which the wind was blowing, measured
clockwise through 360 from north.
