An announcement (which read as follows) was recently Issued by the
Bureau of Commercial Fisheries Biological Laboratory j Honolulu:, concern-
ing an error in depths of reversal computed from the readings of unpro-
tected and protected reversing thermometers s

"Recently,, it was discovered that the depths of reversal of
the Hansen bottles, as calculated at the Honolulu Biological Laboratory
from temperature differences of unprotected and protected reversing
thermometers f are in error ^ These depths ^ x^htch are in excess of the
correct depth, may be reduced to the proper value by the use of a cor-
rection factor J as described below.

At the time the data processing system in use at this laboratory
was being establlsbed^ a table of the factor l/CQxpm) was prepared for
use in computing the depths of reversal from the readings of unprotected
thermometers; Q represents the pressure-constant of an unprotected ther-
mometer, and pm represents the mean density of the water column above
the depth of thermometer reversal, which was taken to be 1,0303 in all
cases. An error occurred in the calculation such thatj instead of
l/CO'tPm)* the table consisted of values of (l/Q)»Pn,, This error is
present in all of the depth data which have been published by this labo-
ratory under its previous name. Pacific Oceanic Fishery Investigations,
and under its present name^ Honolulu Biological Laboratory, up to and
including 1960„ Therefore, in making use of the data published by this
laboratory before 1961 ^ all depths should be corrected by dividing each
by Cfm) 9 which is equal to 1.0615, Multiplication of all the published
depths by 0.942 will give the proper value for the depth of each observa-
tion,"

Subsequent analyses have showtni that the error described above is present
only in the data from those cruises made by vessels of the Bureau of
Commercial Fisheries Biological Laboratory 5, Honolulu, after Hugh M, Smith
cruise 20 (February-April 1953), Cruises for which data containing this
error have been published are listed belov? with the appropriate publica-
tion references.

In conjunction with the Pacific Oceanic Fishery Investigations'
study of the tuna resources of the central Pacific, the hydrography of
Hawaiian offshore waters was investigated during six oceanographic
survey cruises. The first three of these, Hugh M. Smith cruises I,
10, and 12 of December 1949, July 1951, and October 1951, were ana-
lyzed and recorded by McGary (1955). This report covers the ren:iain-
ing cruises 17, 20, and 21 of the Hugh M. Smith, which took place
September 5 to September 15, 1952, February 25 to April 4, 1953, and
August 4 to August 26, 1953 respectively. On Hugh M. Smith cruise 26,
May and June 1954, additional oceanographic data were obtained in con-
junction with skipjack scouting. These have not been analyzed in this
report but are tabulated in the appendix.

The principal observations consisted of routine temperature .

and salinity sampling together with 200-meter oblique plankton hauls.—
Reliable inorganic phosphate-phosphorus data were obtained on cruise
21. The hydrographic data were collected and processed by methods
described by Cromwell (1954), Stroup (1954), and McGary (1955).

Each cruise is discussed separately using a similar outline for
each. A short sumnnary of the cruise report is given first to indicate
the nature of the observations. This is followed by a brief summary of
the weather conditions encountered during the cruise.

The hydrographic data are then analyzed in two major groups,
first those fronn the surface layer and then those from the subsurface
layers. In the former the distributions of temperature, salinity, den-
sity, and surface geostrophic currents are emphasized. In the latter,
attention is focused on the subsurface distribution of nnass and how it
contributes to the surface currents. The results of these analyses are
then briefly summarized.

The report is concluded with a general summary in which the
observations for each cruise are compared in order to point to possible
seasonal variations. The tabulated observations for each cruise are
included in the appendix.

The discussion is generally based on figures in which the
variables are plotted cuid contoured on horizontal surfaces with points
of observation marked by dots. As is generally the case, contour lines

and Hida (1954). Those for cruises 20 and 21 are in preparation for

represent an interpretation of the distribution of a variable and therefore
may be open to dispute. The figures of this report are no exception.
However, no observed points are violated and interpolations are gener-
ally linear except when boundary conditions suggest a deviation.

In order to obtain average values of temperature, salinity, etc. ,
and their spatial trend, the survey region was subdivided into four areas.
A line was drawn along the Hawaiian Island chain and another perpendi-
cular to it through the western tip of Molokai island, as shown on figure 1,
These lines divide the region into a windward (northeast) and a leeward
(southwest) side with an east and a west section in each.

HUGH M. SMITH CRUISE 17

Summary Cruise Report

The cruise began September 5, 1952, and was completed Septenn-
ber 15, 1952. Figure 1 shows the positions of the 31 hydrographic sta-
tions. Water samples were taken to a depth of 600 m. and oblique 200-na.
zooplankton hauls were made on each station. Bathythermograph temper-
atures to 900 feet were obtained on each station and at 10-mile intervals.
Synoptic weather observations were made four times daily and forwarded
to the U. S. Weather Bureau.

Meteorological Conditions

Typical trade wind weather prevailed during the cruise period.
Air temperatures were predominantly 77 F., with the exception of the por-
tion southwest of the island chain, where the maximum deviations of + 2 F,
occurred and where the tennperatures were generally slightly above 77°F.
Winds were generally from 090 + 20 T. with the exceptions of a few sta-
tions to the lee of the island chain where the deviation reached a mciximum
of + 60 . No winds with a westerly component were observed. Speeds
were generally between 15 and 20 knots, with extremes of 6 and 22 knots.
No rain was encountered except on stations 8 and 14.

Surface Hydrography

The hydrographic conditions of the surface layer (upper 50 to
100 m.) are of importance since their variations have a primary

influence upon biological activities. Here the salinity and temperature,
which determine the density of the water, show their greatest seasonal
variations.

Besides effects due to the physical presence of the Hawaiicin
Islands in an ocean stream, one might expect the surface variables to
be influenced by heavy precipitation on the windward slopes of the island
mountains and subsequent runoff. The surface temperature is also ex-
pected to vary because of solar heating in shallow water and in wind-
sheltered regions.

Temperature distribution

Surface bucket temperatures obtained at each bathythermograph
position are contoured on figure 2 at intervals of 0. 5 F. Surface tem-
peratures averaged over the quadrants of the survey region are shown
in table 1 together with the extreme temperatures encountered. Greatest
deviations occurred on the leeward (southwest) side of the island chain.
The maximum temperature of 80,5 F. was found off the west shore of

the island of Hawaii. The lowest temperatures were found in an area

o o o

centered at 20 N. , 157 20'W. , where the minimum was 74.8 F. (This

type of cold temperature distribution was previously shown by McGary
(1955) to be associated with a counterclockwise vortex. ) On the wind-
ward (northeast) side of the island chain temperatures were more uni-
form, with two tongues of warmer water protruding north and northeast-
ward of Molokai and Maui, respectively. On the windward side there was
essentially no change in average temperature from east to west, whereas
on the leeward side the average increased by approximately 1 F. in that
direction.

Salinity distribution

Figure 3 shows the surface salinity distribution contoured at

intervals of 0.05 /oo. Averaged surface salinities are shown in table 1.

o
Maximum salinities (greater than 35.2 /oo) were encountered on the

northern and eastern edges of the survey area and minimum salinities

(less than 35 /oo) off the west shore of Hawaii and along the southern

edge of the survey area. A region of high-salinity water on the leeward

side of the island chain is centered at approximately 19 45'N. , 157°20'W.,

the same location as the temperature minimum.

Density distribution

The surface density of sea water is a function of the independent
variables tennperature and salinity. Their relative importance can be
judged when one considers that the change of surface density in the
Hawaiian Islands region due to a 0. 3 /oo salinity decrease is apjroxi-
mately equivalent to a 1.6 F. temperature increase. Thus, changes in
salinity as shown in table 1 are not negligible in their effect on the density.

Figure 4 shows the surface density distribution in units of sigma-t
with contour intervals of 0. 1. When compared with figures 2 and 3, it
indicates that the main features of temperature and salinity had an addi-
tive effect upon the density distribution; that is, whenever the temperature
was low, the salinity was high, and conversely low salinities corresponded
with high temperatures.

Average surface sigma-t values are listed in table 1,

The

densest water was found in a region centered at 20 N. , 157 15'W. asso-
ciated with the counterclockwise vortex. The average density increased
from south to north and from west t<o east.

Surface circulation

It is not always easy or desirable to make direct current
measurements in order to obtain the circulatory pattern of a region.

Local fluctuations may obscure the average circulation completely,
especially when the observations are nnade over a short period of time.
In one convenient method of indirect current measurement the difference
of the vertical distribution of mass (specific volume) between two sta-
tions is used to calculate the component of the current vector normal
to the line between the stations. There are some essential assunaptions
which must be satisfied. The region under consideration must be sev-
eral degrees of latitude removed from the Equator, a steady state must
exist (no accelerations), and dissipative forces such as friction must be
negligibly small. Another problem in these computations is the proper
choice of a reference level, the surface along which no component of
gravity acts. It is usually assumed that at a depth where the specific
volume change of the water between stations is small connpared to that
in the surface layers, the isobaric surface is "level", i.e. changes are
so small that they will not materially change the computed currents in
the surface layers. To be precise, the computed surface currents are
relative to those at the reference level. ^'

When the method of computing "relative currents, " based on the
"distribution of mass, " is applied to the Hawaiian Islands region, it is
assumed that the restrictions mentioned above hold. However, because
of the boundary effect of the islands, the steady state and the friction
assumptions may not be exactly satisfied, particularly in places of high
current speeds. Distortions in the calculated circulation pattern may
therefore exist, but they are not expected to materially change its prin-
cipal features.

Figure 5 shows the geopotential topography^' in dynaunic meters,
of the sea surface referred to 600 m.Z' The outstanding feature is the
counterclockwise, rotary current motion or vortex centered at about
19 45'N. , 157 20'W. with speeds on the order of 1 to 2 knots. There

are two smaller, clockwise vortices, one off the west shore of the
island of Hawaii and one northwest of the counterclockwise vortex.
West of these vortices, a 0.2-knot current sets north and is deflected
westward south of Kauai Channel.

On the windward side of the island chain the current pattern is
weak except east of Hawaii Island, where a 1/2- to 1-knot current is
setting south, and in the region northeast of Kauai, where a 1/2-knot
current sets first southwest and then changes to west north of Kauai.
The dynamic topography north of the island of Hawaii between 20 and
22 N. indicates a westerly setting drift from east of the survey region
which is deflected to the south.

The geopotential topography both north and south of Kauai Channel
indicates no transport of water through the channel but a flow normal to
its axis in a westerly direction. In Alenuihaha Channel a slow current
setting to the northeast is indicated.

Surface temperature, salinity, and density
and the surface circulation

Figures 2, 3, 4, and 5 show that the major features of temperature,
salinity, and density compare well with the dynamic topography, remem-
bering that in the northern hemisphere the light water is to the right of
the observer facing in the direction of the current (Sverdrup et al. 1942:
394). In the center of the counterclockwise vortex the temperature is
low, the salinity high, and therefore the density is high. The two clock-
wise vortices are not as easily recognized from the surface distribution
of variables, although the high temperatures west of Hawaii suggest one
of them. The other vortex is located in the zone of high current shear
between the counterclockwise vortex and the northerly drift.

The slow clockwise circulation about the island of Hawaii can also
be inferred from the warmer and fresher inshore waters. According to
the dynamic topography the tongues of warmer water protruding north and
northeastward of the islands of Molokai and Maui do not indicate a flow of
water in those directions as much as an intrusion of colder water north
of Oahu and northeast of Alenuihaha Channel.

Thus, north and south of the portion of the island chain between
Oahu and Maui, there is good agreement between the circulation patterns
obtained from the surface density and from the dynamic topography.
West of this region and northeast of Alenuihaha Channel there is a con-
siderable difference. In the southwest part of the survey region and

northeast of Alenuihaha Channel the light water is actually to the left
of the current direction; in the northwest part the direction of flow is
perpendicular to that expected from the density distribution.

The over-all surface density distribution in the survey region
leads to the assumption that the water generally flows in a southeasterly
direction, which is contrary to the surface dynamic heights. These
apparent discrepancies in the rule of direction of flow can be explained
by considering the subsurface distribution of mass.

Subsurface Circulation

A qualitative picture of the three-dimensional subsurface circula-
tion can be obtained by plotting variables on one of several systems of
coordinates. Each of these presentations will illustrate features which
are missed in others. The distribution of temperature, salinity, sigma-t,
oxygen, phosphate, or depth can be presented on vertical planes (sections).
A vertical section of sigma-t, for example, is most useful when it cuts
the direction of flow at right angles. It then gives an indication of rela-
tive current speeds. The distribution of parameters can also be plotted
on "horizontal" planes which are approximately parallel to the sea sur-
face (surfaces of constant pressure or depth). This method is particularly
useful in regions with a complex current system, such as is encountered
in the vicinity of the Hawaiian Islands. Its shortcoming is that vertical
gradients are not apparent.

A useful variation of either method is the use of one of the para-
meters as a coordinate. Such a parameter is the potential density, which
is particularly useful since particle motion taikes place along surfaces of
constant potential density. (The potential density, approximately expressed
in units of signna-t, is the density a particle of water would have if brought
to the surface without loss or gain of heat. ) The deduction of the flow pat-
tern from the distribution of variables on these "sigma-t surfaces" is gen-
erally known as isentropic analysis (Montgomery 1938).

On a horizontal frame of reference, then, one can plot the depth
of a sigma-t surface and obtain its bathymetric chart. For these depths
and on the Scime chart the salinity can then be plotted. Together, the
isopleths of depth and salinity referred to a surface of constant sigma-t
might give an indication of the direction of flow.

The isobaths are generally parallel to the flow, provided that the
slopes of the sigma-t surfaces below are in the same direction. The

direction can be obtained by the use of the rule previously stated. Deep
isobaths represent colunnns of lighter water below the surface and there-
fore will be to the right of an observer facing in the direction of flow.

Flow takes place along the sigma-t or quasi-isentropic surfaces
(Sverdrup et al. 1942:414-416), across which mixing is at a minimum.
Thus, identifying properties of a water mass, such as salinity and tem-
perature, would be retained longest in the direction of flow or, conversely,
the direction of flow would be along the minimum change of the identifying
property such as salinity.

These principles will be used in an attempt to interpret the
subsurface circulation.

Figure 6 shows the sigma-t distribution plotted on a vertical
plane extending from west to east through stations 1, 10, 14, 22, 21,
and 30. The dominating feature of the section is the wave-like distri-
bution of sigma-t west of station 22. The rising isopleths east and west
of station 14 are associated with the "doming" of the sigma-t surfaces
which characterize the counterclockwise vortex mentioned before. The
rule of direction of flow indicates a current setting north between sta-
tions 22 and 14 and one setting south between stations 14 and 10.

The section between stations 1 and 10 demonstrates that the
surface density distribution may give a misleading picture of the surface
current pattern. The 23.0 sigma-t isopleth slopes from 20 m. at sta-
tion 1 toward the surface at station 10, whereas the 23.2 sigma-t isopleth
and all those below its depth slope down. Thus, the surface density indi-
cates a southerly component of flow when in reality there exists a strong
northerly component.

East of station 22, the varying slopes of the sigma-t isopleths
make estimation of the surface current speed and direction difficult
without actual dynamic computations. In Alenuihaha Channel (stations
22 to 21) the absence of a pattern associated with well-developed currents
is to be expected, since a strong flow normal to the channel direction is
not likely.

The depth variations of the 27.0 sigma-t isopleth west of station
22 shows that the distribution of mass associated with the counterclock-
wise vortex extends to depths greater than 600 m. It also indicates the
possibility that currents at that depth are not negligible. But since the
direction of slope of the isopleth is the same as those above, the error

is expected to be in magnitude of the surface currents only and not in
their direction.

The salinity distribution is also shown in figure 6 by means of
dashed lines (isohalines). A salinity maximum is generally to be found
at approximately 100 m. and a minimum at approximately 400 m. The
salinity maximum east of station 22 is greater than 35.2 /oo and west
of station 14 less than 35. 2 /oo. In the vicinity of the counterclock-
wise vortex this salinity structure has broken down with a disappearance
of the maximunn, which now occurs as a pocket at the surface.

A better over -all picture of the circulation can be obtained from
the bathymetric charts of sigma-t surfaces. Figure 7 shows a series
of charts for the depths of the 26. 5, 26. 0, 25. 5, 25. 0, 24. 5, and 24. 0
sigma-t surfaces which will convey to some degree the three-dimensional
changes in the distribution of mass associated with the circulation. The
dashed lines indicate the salinity distribution on the sigma-t surfaces.
However, due to the complexity of the circulation and to lack of detail
and precision, the usefulness of salinity as a tracer is considerably
impaired, so the flow pattern will be deduced from the isobaths.

According to the 26.5 and 26.0 sigma-t surfaces, the direction
of flow north of the island chain is fronn east to west and the deflecting
effect of the islands of Hawaii and the group from Maui to Oahu is
apparent. The 25.5 and 25.0 sigma-t surfaces indicate a general
change of direction to the northeast in the same region. Finally the
24.5 and 24.0 sigma-t surfaces show a southeasterly drift on the wind-
ward side except north of Kauai and Kauai Channel, where the flow is
from the north.

South of the islajid chain the flow on the 26. 5 sigma-t surface is
generally toward the northwest. The position of the counterclockwise
vortex is clearly indicated by the 380-m. isobath. The other surfaces
show that the vortex features become increasingly dominant toward the
surface. In the survey region south of Kauai the northerly component
of flow prevails up to the 24.0 sigma-t surface.

In figure 7 the layers which are identified by constant sigma-t
values can be considered as independent current systems which, when
added together, produce the net surface current. This, essentially, is
done in dynannic calculations, using isobaric rather than sigma-t
reference surfaces.

The three-dimensional water body of the survey region, extending
down to 600 m. , can be separated into the surface layer and two inter-
mediate layers. The upper intermediate layer is centered about the
salinity maximum, corresponding approximately with the 24. 5 sigma-t
surface (see fig. 22 for typical temperature-salinity diagrams). The
lower layer is centered about the salinity minimum, corresponding
approximately with the 26. 5 sigma-t surface. The distribution of mass
in each is associated with a current pattern and these patterns, when
added vectorially, give the net surface circulation. Thus figures 8 and
9, the geopotential topographies at 300 m. relative to the 600-m. level
ajid the geopotential topography at the surface relative to the 300-m.
level, illustrate the relative flow pattern of the lower intermediate layer
and the upper intermediate layer (including the surface layer), respec-
tively. These, when added, give the surface circulation relative to the
600-m. level (fig. 5).

Bathythermograph Data

Figure 10 represents the vertical bathythermograph temperature
distribution oriented in sections from north to south along the lines of
stations. At this stage of analysis little additional information can be
obtained from these figures, and they are included as a record only.
The counterclockwise vortex is clearly indicated by the rising isotherms
between stations 12 and 15.

Summary of Cruise

The survey data obtained on cruise 17 of the Hugh M. Smith
represent typical summer conditions with normal trade wind weather
prevailing. The counterclockwise vortex west of Hawaii was found on
previous cruises, which have been discussed by McGary (1956). Two
circulation systems were emphasized, the lower intermediate which is
associated with the salinity minimum and the upper intermediate which
is associated with the salinity maximum. The former consisted of
westerly-setting currents north of the islaund chain which showed the
effect of the islajid barrier. The latter indicated southerly-setting
currents impinging on the island chain which were deflected to the
southeast by the island group from Oahu to Maui. On the leeward side
the upper intermediate circulation was dominated by the counterclock-
wise vortex. The results of these two systems, together with the sur-
face distribution of nnass, is a rather compliccited net surface pattern
as shown by the geopotential topography (fig. 5).

HUGH M. SMITH CRUISE 20

Summary Cruise Report

Cruise 20 of the Hugh M. Smith extended from February 25, 1953,
to April 4, 1953. The area covered was essentially the same as that of
previous survey cruises in the offshore waters of the Hawaiian Islands,
except for the extension of the western limit to 16 1 30'W. and the south-
ern limit to 17 20'S. In addition there were two exploratory lines of
stations up to 29°N. along 155 W. and 158 W.

Figure II shows the position of the 69 hydrographic stations where
water sannples were collected to a depth of 1,000 m. Oblique zooplankton
tows were made to a depth of 200 m. on each station except station 34,
where a surface tow was made. Other observations were as follows; bathy-
thermograph lowerings on each station and one between stations; four
daily synoptic weather observations, which were passed on to the U. S.
Weather Bureau; and GEK observations at each bathythermograph posi-
tion. These latter were made with unfloated electrodes except on 3 3
occasions where duplicate GEK runs were made with floated electrodes.

The hydrographic survey part of the cruise began on March 9, 1953.
Station 12 was occupied March 15 so that the region south of 24 N. , the
main survey region, was covered in 19 days.

Meteorological Conditions

No greatly varying weather conditions were encountered throughout

the cruise. North of latitude 24 N. the air temperature decreased from

71 F. to 66.5 F. at stations 6 and 7. The average temperature over the

whole of the main cruise area was 73 F. Within this area the average air

o
temperature encountered north of the island chain was 72 F. , with extremes

of 71 F. and 75 F. , and to the south it was 74 F. with extremes of 73 F.

and 77°F.

o o

Winds were predominantly from 080 T. and ranged from 40 to

130 T. On only ten stations did they have a southerly component. Wind

speeds were predominantly within a range of 15 to 22 knots. On only six

stations was it greater than 22 knots, with a maximum of 30 knots.

Calmer weather (winds less than 15 knots) prevailed during the latter

part of the cruise, between stations 52 and 61.

Light rain was encountered on five stations which were scattered
throughout the cruise.

Temperature distribution

The surface bucket temperatures obtained at each bathythermograph

position are contoured on figure 12 at 0.5 F. intervals. The minimum

o o

tennperature of 71.8 F. south of 24 N. was measured at station 12 and

the maximum of 76. 3 F. at station 56. Average temperatures showed

no significant change from east to west on either side of the islcind chain.

There were no outstanding features, such as centers of cold or
warm water, in the surface temperature distribution. A tongue of warm
water extended from the vicinity of stations 59 and 60 northeastward,
branching toward Molokai and Hawaii. Two other tongues of relatively
warm water extended northward north of Alenuihaha Channel toward sta-
tion 13 and north of Molokai toward station 24.

In the exploratory section north of 24 N, the surface temperature
assumed a more regularly decreasing pattern toward the north. South of
26 N. temperatures tended to increase toward the west, whereas north
of this latitude they decreased toward the west.

12

Salinity distribution

Figure 13 shows the distribution of surface salinity contoured at
o ^

0, 1 /oo intervals. As in the case of the surface temperature distribu-
tion, there were no outstanding features. Relatively large salinity gra-
dients were encountered east of Hawaii and between 159°W. and 160°W.
along the southwest edge of the survey region. A tongue of high salinity
water extended south toward and through Kauai Channel until south of
Kauai it turned west.

Table 2 shows that the average salinity increased from east to
west on each side of the island chain, with extremes of approximately
34.4 /oo and 35.3 /oo. Considering the whole cruise area, the salin-
ity increased on the average from south to north, reaching a maximunn
at approximately 26 N. , and then decreased towards 29 N. South of
26 N. the salinity increased from east to west whereas north of this
latitude it decreased.

Density distribution

Figure 14 shows the surface density (sigma-t) distribution with
contour intervals of 0. 1. Both north and south of the islands the density,
on the average, increases toward the west, and when figures 13 and 14
are connpared, other similarities between the isopleths of salinity and
sigma-t become apparent. Some of these are the relatively large gra-
dients east of Hawaii, between 159 W. and l60 W. at the southern edge
of the survey region, and high and low salinities south of Kauai and in
the vicinity of station 49 which correspond with pockets of high and low
sigma-t values, respectively. Thus, south of the island chain the salin-
ity materially influences the surface density distribution, becoming less
important on the windward side until north of 24 N. the temperature plays
a dominant role.

o

It was noted above that at 26 N. the salinity and temperature show

changes in trend. These are also reflected in the surface density distri-
bution (fig. 14), suggesting that 26 N. may be the southern boundary of a
region generally referred to as the subtropical convergence. (See p. 15,
Subsurface Circulation. )

Surface circulation

Figure 15 shows the surface circulation represented by the dynamic
topography relative to 1,000 m. The survey region is dominated by a num-
ber of vortices, some cyclonic, others anticyclonic (counterclockwise,
clockwise), centered in the vicinity of stations 49, 39, 1, and 23. The

13

latter is a large circulatory system which extends from approximately
21°N. to 27°N.

Regions of high current velocities (of the order of 1 to 2 knots)
are found in the vicinity of stations 44, 42, 50, 58, west of station 12,
and elsewhere. Most of these are on the periphery of the vortices men-
tioned above.

Figure 15 also shows that the area north of 27 N. is one of
stagnation (no currents) except for a northeasterly drift in its northwest
section.

Geomagnetic Electrokinetograph (GEK) observations

The GEK (von Arx 1950) observations are plotted on figure 16
in which the arrows indicate the direction of flow and numbers the speed
in cm. /sec .

On 33 GEK stations duplicate determinations were made with
floated (dotted arrows) and unfloated electrodes in order to determine
the validity of the "droop" correction (McGary 1955:8). Figure 16 shows
that in many cases there was good agreement between the two methods.
For a number of observations, however, the currents obtained by the
two methods were 90 or more apart, particularly when the GEK indi-
cated low current speeds.

The GEK data have been presented only as a record, and no
detailed analysis in relation with the geostrophic—' currents has been
attempted. However, a superficial comparison between the two nnethods
of obtaining surface currents shows some resemblance, particularly in
regions of high current speed. North of 26 N. , in the region of weak
currents, there is little agreement between the two methods. The region
south of 24 N. is one of much vortex activity where it is reasonable to
expect vortices both of smaller dimensions and shorter life. Here the
GEK which measures essentially instantaneous currents, would be ex-
pected to deviate from the geostrophic flow.

Surface temperature, salinity, and density
and the surface circulation

It would be desirable to be able to interpret the flow pattern from
the distribution of the surface salinity, temperature, and density. In
the lee of the island chain some confirmation of the flow pattern is derived

5/ ^

— Geostrophic currents are those obtained from the geopotential

topography.

14

from these variables. For example, one branch of the forking tongue of
warm water is associated with the high velocity current in the vicinity
of station 50, and the other with the current at station 42. The latter
current continues past the southern tip of Hawaii and corresponds to the
large salinity and density gradient in that region. The clockwise vortex
centered in the vicinity of station 49 is again apparent fronn both the sa-
linity cuid density distribution, as is also the southeasterly setting current
near station 58. In Kauai Channel the tongue of high- salinity water is
compatible with the dynamic topography, which shows a strong south-
westerly setting current coming from the vicinity of the high- salinity
source area northwest of the main survey region.

North of the island chain the surface variables are of little help
in deducing the flow pattern and, as before, it is expected that the sub-
surface distribution of variables will help to clarify the picture.

Subsurface Circulation

As in the case of cruise 17, investigation of the subsurface
circulation involved the two internriediate systems. The depth of the
24. 5 sigma-t surface associated with the salinity maximum and the depth
of the 26. 5 sigma-t surface associated with the salinity minimum are
shown in figures 17 and 18. -They indicate that the vortices revealed by
the surface dynamic topography do not always extend through the two in-
termediate flow systems. For example, the vortex near station 39,
southwest of Oahu, is clearly apparent on figure 17 but not on figure 18,
whereas that at station 49 is apparent on both sigma-t surfaces. North
of the island chain the vortex at station 23 is apparent on figure 17 only,
and that at station 1 is well pronounced on the 26. 5 sigma-t surface only.
To illustrate that the complex surface structure extends to great depths,
figure 19, showing the depth of the 27.2 sigma-t surface, has been
included.

It is interesting to note in figure 17 the rise of the 24. 5 sigma-t
surface northward until at approximately 26 N. it reaches the sea sur-
face. On the basis of isentropic theory this would be the latitude where
the maximum salinity water originates (Sverdrup et al. 1942:141-146) •

In figure 20, showing the surface dynamic heights relative to the
300-in. level, the four vortices mentioned above are readily distinguish-
able.

In figure 21, the dynamic heights at 300 m. relative to the 1, 000-m.
level, the vortex at station 49 appears considerably weaker and that at
station 39 is indistinguishable. North of the island chain the vortex at

15

station 23 has all but disappeared, whereas that at station 1 has retained
a strength similar to that which it showed in the upper layer. Thus the
two systems added together give a generally intensified surface flow rela-
tive to the 1,000-m. level.

So far the complex current pattern has given no infornnation about
any net circulation through the survey region. To gain an understanding
of this the dynamic heights of figures 15, 20, and 21 were averaged in
each of the four sections of the survey region and north of 24 N. in the
exploratory region. These averages are shown in table 3 below.

This shows that there is a westerly drift of the lower intermediate water
mass in the northern portion of the cruise area. In the main survey re-
gion there appears to be a slight southwesterly drift. The surface circu-
lation relative to the 300-m. level shows a drift, slightly stronger than
the intermediate, setting southeast. These two combine to give a net
southeasterly surface drift relative to 1, 000 m. along the island chain
and little net flow in the northern section of the survey region.

Further interesting information can be obtained from an analysis
of the salinity minimum. This was suggested by the characteristic shape
of temperature salinity diagrams, some of which are shown in figure 22.
At station 5, for example, the temperature, salinity, depth, and sigma-t
of the salinity minimum are 5.3 C. , 33. 97 /oo, 620 m. , and 26. 8 respec-
tively. At station 62 these same variables are 11.3 C, 34.18 /oo, 270 m.,
and 26. 1. These are the extreme values, the former representing a type
of water found in the northern section of the cruise area, and the latter a
type found in latitudes south of the island of Hawaii. Values between these
extremes are found throughout the remainder of the survey area. Some of
the curves also indicate a double minimum, such as at stations 61 and 64

16

(fig. 22). This suggests that the islands are located in a region bounded
by intermediate water masses from a different source and supports the
schematic figure 202 in Sverdrup et al. (1942:717).

Also interesting to note is the shape of the T-S curve at the
salinity minimum. There are a number of stations such as station 29
(fig. 22), where the salinity remains essentially constant between the
extremes of sigma-t mentioned above, which might suggest mixing of
the two types of water.

To illustrate these observations, figure 23 has been prepared
showing schematically two types of water at the salinity minimum which
were separated arbitrarily at 26. 5 sigma-t. Cross-hatched zones in-
clude the stations of constant salinity throughout the sigma-t rajige. The
lack of a more definite flow pattern on this diagram is in agreement with
the averaged dynamic heights for the lower intermediate flow, which show
only a weak net circulation.

Bathythermograph Data

Bathythermograph data are again included as a record only in
vertical sections on figure 24.

Summary of Cruise

Cruise 20 of the Hugh M. Smith took place during oceanic winter
conditions with trade wind weather.

The hydrographic data showed considerable complexity extending
down through the salinity minimum layer with four major vortices which
obscured any mean flow pattern. Average dynamic heights at 300 m.
relative to 1, 000 m, indicated a southwesterly drift through the main
survey region. Those at the surface relative to the 300-m. level re-
vealed a slightly stronger easterly drift. These two systems combined
to give a net easterly flow along the island chain and no net current in
the northern section of the survey region.

The large number of vortices show that the survey region is one
of dissipation of energy with little or no net transport. The absence of
any "streams" impinging on the island chain either at surface or inter-
mediate depths suggests the existence of mechanisms for vortex genera-
tion other thaji those associated with current shears.

HUGH M. SMITH CRUISE 21

Summary Cruise Report

The cruise began August 4 and was completed August 25, 1953,
with the occupation of 69 stations whose location is shown in figure 25.
All of these were hydrographic stations with sampling depths to 500 m.
except 23 and 33, which were trawl stations. Three duplicate sets of
four stations were occupied in Kaiwi Channel, but only stations 28, 29,
30, and 3 1 of these are used in the analysis in order to provide better
continuity in time. Station 5 was occupied on August 6 and station 65
on August 24, so that the survey region was covered in 18 days.

Other observations included 200-m. oblique plankton tows and
bathythermograph and GEK observations at each station and at 20-mile
intervals. Four daily synoptic weather observations were made and
passed on to the U. S. Weather Bureau.

Meteorological Conditions

Typical trade wind weather was encountered during the cruise.
The overall average air temperature was 77.3 F. On the windward side
the average was 76.6 F. and on the leeward side 77.8 F. The lowest
tennperature of 75. 1 F, was encountered at station 9 and the highest,
81 F. , at station 32 in the immediate lee of Lanai Isleind. Of the winds
which were measured on the hydrographic stations, 65 percent were from
070° to 090°T. ; 90 percent of the winds came from 050 to 120°T. The
winds had an extreme southerly connponent on only two occasions, namely
on stations 37 and 38 when the direction was 220 T. and 170 T. , respec-
tively. The measured wind speeds were 46 percent between 17 and 21
knots, 30 percent between 11 and 16 knots, 12 percent greater than 21
knots, and 12 percent less than 11 knots.

The weather was generally fair except on stations 5 to 8, 37, and
46, when showers were encountered.

Surface Hydrography

The distribution of the surface temperature, salinity, and density
are again discussed separately. Table 4 shows these variables averaged
over the quadrants of the survey region together with the extreme values
encountered.

Temperature distribution

The surface bucket temperatures obtained at each bathythermograph
position are contoured on figure 26 at 0.5 F. intervals. As during cruise
17 (September), the greatest deviations occurred on the leeward side, where
naaximum temperatures of about 79. 5 F. were found west of the island of
Hawaii, in the vicinity of station 37, along the southern border of the sur-
vey region between stations 59 and 65, and between stations 40 and 41,
south of the island of Oahu. The coldest water, 76. 6 F. , on the leeward
side of the island chain was found in the southeast section of the survey
region and in a pocket at station 51. On the windward side the tempera-
tures were more uniform, as was also the case during cruise 17, and
ranged from 76. 3 F. in the east to 77. 7 F. in the west.

The increasing average temperatures from east to west on both
sides of the island chain suggest that there exists a net surface flow with
a westerly component, considering that the survey region is located within
latitudes of net gain of heat energy. On the leeward side, the higher tem-
peratures and the greater deviations suggest a slower surface transport
to the west. Noteworthy is the horizontal temperature gradient along the
island chain. This and the other features point to the assumption that water
with a westerly component of flow is impinging on the island chain, which
provides an effective barrier.

19

Salinity distribution

Figure 27 shows the surface salinity distribution contoured at

0. 1 /oo intervals. On the windward side the maximum salinity of

35.27 /oo was found at station 8 and at stations 10 and 15, in a tongue

extending from north to south toward the island of Hawaii, where the

o o

salinity was 35.26 /oo. The lowest salinity, 34,79 /oo, was found

at station 5. On the leeward side the maximum salinity of 35. 11 /oo
was found at station 63 and the minimum of 34.82 /oo at station 58,
both along the southern boundary of the survey region. Also of interest
is the pocket of higher salinity at station 51. In general, the average
salinity decreased westward north of the island chain whereas it in-
creased in that direction south of the islcinds.

An isolated pocket of low salinity water (34.55 /oo), lower than
the minima mentioned above, was found at station 26 in Kauai Channel.
Although this seems unreasonably low, no reason such as faulty sam-
pling or chemical analysis can be found to discard the observations.

Density distribution

The surface density distribution in units of sigma-t was contoured
at 0. 1 intervals on figure 28. It shows that on the windward side the ex-
treme sigma-t values were found at station 5, where the minimum was
23.21, and at station 10, where the maximum was 23.59. On the leeward
side the highest sigma-t value, 23.47, was found at station 51, and the
lowest, 22.92, at station 35 west of Hawaii and station 40 south of Oahu,

Figures 26, 27, and 28 indicate the relative influence of tempera-
ture and salinity in the density distribution. For example, the surface
temperature and density show the feature of relatively large horizontal
gradients along the island chain, which is absent in the salinity distribu-
tion. One can also note the pockets of warm water south of Oahu and west
of Hawaii corresponding with lower densities in the same regions.

On the windward side of the island chain one cam detect the
influence of salinity in the surface distribution of density. For example,
north of the island of Hawaii the tongue of saline water extending from
north to south is reflected in a tongue of denser water in spite of higher
surface temperatures. This indicates that the salinity has become the
dominant variable in the density distribution. At station 51, on the lee-
ward side, it can be seen how both low temperature and high salinity
contribute to the high density, which, as before, "is associated with a
counterclockwise vortex.

20

In general, the average surface density decreases from east to
west and south to north. Thus, remembering that in the northern hemi-
sphere the light water is to the right of an observer facing in the direc-
tion of flow, the density distribution suggests that the contribution to the
net surface flow is a relative current setting southeast.

Surface circulation

For cruise 21 dynamic calculations are limited to the upper
500 m. These depths (500 m. ) are approximately the depths of the
salinity minimum during this cruise. A considerable part of the con-
tribution toward the surface flow due to the intermediate distribution
of mass is therefore not shown. This, however, is not expected to
change materially the presentation of the main features of the circulation.

The dynamic topography at the surface relative to the 500-m.

level (fig. 29) shows that the survey region is again one with a complex

flow pattern. There appear in the lee of the islands three vortices.

Two of these, centered in the vicinity of stations 47 and 51, show a

counterclockwise rotation, and the larger, third vortex, centered in

the vicinity of 20 N. , 158 W. , shows a clockwise rotation. Highest

current speeds in the order of 1 to 2 knots occur again on the periphery

of the vortices. In the northern section of the survey region an easterly

o o y o

current turns south between 157 and 158 W. and then flows west just

north of the island chain. North of Hawaii a southwesterly current enters

the survey region and is deflected to the southeast off the island's coast.

The circulation about the island of Hawaii is clockwise.

Geomagnetic Electrokinetograph (GEK) observations

The GEK surface current vectors are plotted in figure 30. The
arrows indicate the direction of flow and numbers the speed in cm. /sec.
All observations were made with unfloated electrodes and subsequently
corrected for the "droop" effect.

As before, no detailed analysis is made, but when figures 29 and
30 are compared, agreement between GEK and geostrophic current direc-
tion and relative speed is apparent. High GEK speeds occur between the
major vortices of figure 29, and the directions there as well as in regions
of lower current speed are in good agreement. Interesting to note is the
agreement between the GEK currents and the geostrophic current in Kauai
Channel. Both figures 29 and 30 show northwesterly flow in the eastern
part and southwesterly flow in the western part of the channel.

21

The agreement of the two methods is general only, and instances
° o o

such as at stations 19 and 22, where the directions are 90 to 180 out

of phase, can be found. The GEK current speeds also appear higher by

as much as a factor of 2, as between stations 57 and 58.

Surface temperature, salinity, density
and the surface circulation

As before, the surface distribution of variables is of little help
in deducing the flow pattern. Only the counterclockwise vortex at sta-
tion 51 is apparent in figures 26 and 27 fronri the low temperature and
high salinity, respectively. The sigma-t distribution together with the
high temperatures west of Hawaii suggest a clockwise circulation about
the island. North of Hawaii, figures 27 and 29 show that the tongue of
high salinity water is carried into the survey region by the southeasterly
setting current.

The lack of agreennent between the flow expected fronn the surface
density distribution and that obtained from the dynannic height anomalies
again points to the importance of the subsurface distribution of mass.

Subsurface Circulation

The bathymetric chart of the 24. 5 sigma-t surface approximately
associated with the salinity maximum is shown in figure 31. The isobaths
clearly indicate the three vortices in the vicinity of stations 45, 49, and
51. The counterclockwise vortices are identifiable by "doming" and the
clockwise vortex by a depression in the sigma-t surface. The resem-
blance between the isobaths of the 24. 5 sigma-t surface cund the dynamic
height contours at the surface relative to 250 m. (fig. 32), both north
and south of the island chain, should be noted. This means that the bathy-
metric chart of the 24. 5 sigma-t surface essentially indicates the rela-
tive flow of the intermediate layer, associated with the salinity maximum.
This also suggests that the distribution of mass on the salinity nnaximum
layer (sigma-t 24. 5) is of greater importance than the surface distribu-
tion of mass (fig. 28).

The bathymetric chart of the 26. 5 sigma-t surface, approximately
at the salinity minimum, is presented in figure 33. Evidence of vortex
motion southwest of the island chain is still apparent but less distinct.
The location of the counterclockwise vortices is indicated by ridges pro-
truding into the survey region from the southwest, and the clockwise
vortex is indicated by a trough extending southward from the Oahu and
Molokai region,

22

The contribution to the surface circulation due to the intermediate
flow associated with the salinity minimum is illustrated by the dynamic
topography at 250 m. relative to the 500-m. level (fig. 34). It can be
seen that the vortices in the vicinity of stations 49 and 51 extend to the
depths of the salinity mininnum. The vortex at station 45 is, however,
obscured by a northeasterly setting current, the direction of which is
reversed south of Oahu and in Kaiwi Channel to continue as the westerly
setting current south of Kauai. Similar isopleth patterns in figures 33
and 34 again show that the isobaths of the 26. 5 signna-t surface at the
salinity minimum give a good indication of flow in this layer. Discrepan-
cies can probably be attributed to the fact that the dynamic height at 250 m.
relative to the 500-m, level reflects the distribution of mass only in the
upper portion of the flow layer associated with the salinity minimuna.

The salinity distribution on the 24. 5 and the 26. 5 sigma-t surfaces
is also indicated by dashed lines in figures 31 and 33 and becomes plaus-
ible if studied in conjunction with the dynamic topography at the surface
relative to the 500 m. and that at 250 m. relative to the 500-m. level.
The usefulness of tracing currents by this method, however, is impaired
by the complexity of the system.

A comparison of the dynamic heights presented in figures 29, 32,
and 34 shows that the major features in the two intermediate systems are
quite similar and generally have an additive effect on the net surface cir-
culatory pattern. The spacing of the contour lines southwest of the island
chain is closer in figure 32 than in figure 34, which means that the con-
tribution due to the intermediate system associated with the salinity max-
innum is of prinnary importance. Northeast of the island chain the contour
line spacing is approximately the same in the two figures, indicating that
there the two systems contribute equally.

Differences in the contour line patterns of the two systems (figs.
32 and 34) exist north of the islands of Kauai and Oahu and in the vicinity
of station 47. The clockwise circulation about the island of Hawaii is
also absent in the deeper flow pattern (fig. 34).

The averaged dynamic height anomalies at 250 m, relative to the
500-m. level in each subdivision of the survey area show a net drift
toward the island chain from the northeast which is deflected to the
northwest. The sanne computations for the surface flow relative to the
250-m. level also show a net drift toward the island chain from the north-
east, which in this case is deflected toward the southeast. The net motion
on the leeward side of the island chain appears negligible in each case.
These observations are in agreement with the averaged dynamic heights

23

at the surface relative to 500 m. , where the northwesterly current
impinging on the island chain is deflected to the northwest and southeast.

Bathythermograph Data

As before, the bathythermograph data have been included as a
record only and are presented by vertical sections in figure 35.

Inorganic Phosphate

On Hugh M. Smith cruise 21 good, reproducible inorganic
phosphate data, analyzed aboard ship by the method described by Wooster
and Rakestraw (1951), were obtained. The surface values were plotted
on figure 36 and show little variation. The average phosphate-phosphorus
concentration on the windward side of the island chain was approximately
0.2 (ig-at/1 and on the leeward side 0.3 [Jig-at/l. A tongue of low-phosphate
water (less than 0.2 [j.g-at/1) reached into the survey region between sta-
tions 5 and 9 and extended toward the island of Hawaii. This is in good
agreement with the surface currents as shown in figure 29. A tongue with
a high phosphate concentration (greater than 0.4 |jig-at/l) appears between
stations 58 and 60 and extends to station 39, between the counterclockwise
and clockwise vortices centered in the vicinity of stations 51 and 49 (fig. 29).

Figure 37 dhows the phosphate distribution on the 24. 5 sigma-t
surface. In general the average concentration is lower on the windward
side (0.2 fig-at/l) than on the leeward side (0.3 fig-at/l). Interesting to
note is the similarity of the isopleth structure of phosphate-phosphorus
cind salinity (fig. 31) on the windward side of the island chain. On the
leeward side, the outstanding feature is the pocket of low-phosphate water
(less than 0.2 fj.g-at/1) in a region where the average concentration is
greater than 0. 3 (ig-at/l. This pocket is located in the vicinity of sta-
tion 39, to the northeast of the clockwise vortex (fig. 29), within a tongue
of lower phosphate water extending southward through Kaiwi Channel.

The phosphate distribution on the 26. 5 sigma-t surface is shown
in figure 38, where again the concentration is lower on the windward side
(generally less than 2 fig-at/l) than on the leeward side (generally greater
than 2 (ig-at/1). A tongue of lower phosphate water reaches southward
through Kauai Channel toward station 49, and ajiother through Alenuihaha
Channel to station 38. Again there are similarities in the isopleth struc-
ture of the phosphate and salinity concentration (fig. 33) on the 26. 5
sigma-t surface.

Summary of Cruise

Cruise 21 of the Hugh M. Smith took place during summer
conditions, with typical trade wind weather prevailing. The systems
identified by the salinity minimum, the salinity maximum, and the sur-
face waters were again investigated separately. It was shown that the
surface current pattern southwest of the island chain was primarily
influenced by the system associated with the salinity maximunn (fig, 32,
which in its computation includes the surface distribution of mass).
Northeast of the island chain the dynamic connputation showed that the
lower intermediate system and the upper intermediate system together
with the surface system were of approximately equal importance.

There was little or no net transport of water through the survey
region on the leeward side in either of the intermediate systems. On
the windward side water was renewed from the north or northeast and
then deflected both to the northwest and southeast. The northwest de-
flection was primarily due to the flow associated with the salinity
minimum.

GEK observations showed general agreement with currents
obtained from dynamic computations. This might be expected when
one considers that the system during the summer becomes less complex
and that therefore the instantaneous GEK observations are in closer
agreement with average current conditions.

Inorganic phosphate observations showed that the surface concen-
tration on the leeward side of the island chain was greater than on the
windward side, although the difference was small. This suggests, as
was shown by dynamic computations, that on the windward side there
exists a continuous influx of new, low-phosphate water. On the leeward
side, the stationary surface waters may be enriched by vertical mixing
or island drainage.

DISCUSSION

The purpose of this report has been the presentation of data
which were collected on cruises 17, 20, and 21 of the Hugh M. Smith.
Two of these occurred during the summer months of August and Septem-
ber and one during the winter months of February and March.

The data for each cruise were examined separately, first the
surface and then the subsurface layers. Important and interesting

25

features were pointed out, but in general no attennpt has been made to
interpret or explain them. It is felt that the information gained fronn
each cruise is but a fragn^ent of the oceanographic picture of the
Hawaiian Islands region and a more complete understanding must wait
until all the available data can be synthesized.

Surface Variables

The surface layer has been given special attention because in it
the primary production of the sea takes place. The surface parameters
of temperature, salinity, and density can also be used as indices of
seasonal and longer period changes in the oceanic environment.

An understanding of the surface temperature is particularly
useful because of the easy manner in which it can be measured by ther-
mometer and bath -thermograph. Generally temperature is the important
independent variable in the density distribution, which in turn is used to
obtain the relative current picture. In the Hawaiian Islands region, how-
ever, it was shown that salinity is also important in the distribution of
surface density.

Table 5 below summarizes for each cruise the averaged surface
tennperature, salinity, and density (sigma-t) in the four sections of the
survey region. On the basis of data from one winter and two summer
cruises, one can only hint at the seasonal trends and point to interesting
features. By studying the temperature, for example, one finds that the
seasonal range is about 4 F. , which is less than the extreme range of
almost 6 F. encountered during cruise 17. The extreme ranges on the
windward and leeward sides of the island chain on cruises 20 and 21 did
not indicate any clear seasonal trend. The leeward side of the island
chain was dominated during cruise 1 7 by a large counterclockwise vortex,
whereas during cruises 20 and 21 there were a number of smaller vor-
tices in this region. Thus, the temperature range might indicate the
type of vortex activity.

Although the average salinities changed from cruise to cruise,
no seasonal trend is indicated. Figures of the surface salinity distri-
bution suggest that the changes are not due to island runoff only, but
also to varying concentrations outside the survey region.

It is interesting to note that the salinity range in each cruise
shows a seasonal trend. On cruise 17 (summer) the extreme range
was about 0.3 /oo, on cruise 20 (winter) 0.9 /oo, and on cruise 21
(summer) 0. 5 /oo. Another interesting feature is the slightly

increasing trend of salinity from west to east during cruise 17, and a
more definite increasing trend from east to west during cruise 20 on
both sides of the island chain. During cruise 21 the salinity increased
fronn west to east on the windward side and from east to west on the
leeward side of the island chain.

Variations in the average surface sigma-t values show the
combined effects of the temperature and salinity variations. The sigma-t
values are higher in winter than in summer and for each cruise they are
also higher on the windward side of the islands, reflecting the tempera-
ture effect. The greater range in extreme values of sigma-t for the win-
ter cruise than for the summer cruises reflects the influence of salinity
on the density.

It is interesting to note that the sigma-t values increased from
southwest to northeast during the summer cruises and from south to
north during the winter cruise. Thus, the relative current due to the
surface distribution of mass would drift southeastward in summer and
eastward in winter.

Surface Currents

The investigation of surface variables was followed by a study of
the surface current pattern, which generally was one of complexity with
little net transport through the survey region.

The dynamic topography (fig. 5) of cruise 17 showed that the
leeward region was dominated by a large counterclockwise vortex. The
currents on the windward side appeared to be very weak, except for one
in the region north of Kauai setting southwest at approximately 0.4 knots.

The dynamic topography of cruise 21 (fig. 29). showed two
counterclockwise vortices in the lee of the island chain. The position
of the counterclockwise vortex of cruise 17 was now occupied by a large
clockwise vortex. The current pattern on the windward side of the
island chain also appeared nnore complex than on cruise 17.

The most confusing current pattern was shown by the dynamic
topography of cruise 20 (fig. 15), when both sides of the island chain
were dominated by vortex motion apparently without a systematic pattern.

Subsurface Circulation

The currents deduced from the surface density (the light water
is to the right of an observer facing in the current direction) were not

28

always in agreement with those obtained from surface dynamic heights.
This emphasized the importance of the subsurface distribution of mass.
The survey data indicate three major systems within the POFI sampling
depths: the system associated with the surface distribution of nnass,
that associated with the salinity mciximum, and that associated with the
salinity minimum.

The 24. 5 and 26. 5 sigma-t surfaces were generally associated
with the salinity maximum and the salinity minimum, respectively.
Their isobaths would give an indication of the direction of flow at these
levels. Conventional isentropic analysis, however, such as plotting the
variation of a tracer, like salinity, on surfaces of potential density
(sigma-t) was not successful in the Hawaiian Islands region.

The relative importance of the systems associated with the
salinity maximum and minimum was further investigated by means of
dynamic height anomalies in these layers. The reference levels were
the maximum sampling depths (600 m. for cruise 17, 1, 000 m. for
cruise 20, and 500 m. for cruise 21) and the approximate depth of the
inflection point between the salinity maximum and the salinity minimum
on the tennperature-salinity diagram (fig. 32). Thus for cruise 17 the
contribution to the net surface flow due to the system associated with
the salinity minimum would be represented by the dynamic height anoma-
lies at 300 m. relative to the 600-m. level. The contribution to the net
surface flow due to the upper layer, associated with the salinity maxinrium
and the surface distribution of mass, would be represented by the dynamic
height anomalies at the surface relative to 300 m. The latter gives the
current directions and magnitudes relative to the currents at 300 m. (The
concept of relative motion is familiar to navigators, for because of current
nnotion the actual path of a vessel nnay be quite different from either the
course steered or the current direction.) This presentation shows the re-
lative importance of the distribution of mass associated with two subsurface
flow systems, the upper of which would include the effect due to the surface
distribution of mass.

The dynamic topographies of the intermediate water masses
associated with the salinity minimum of the three cruises were shown in
figures 8, 21, and 34. In each case any net flow through the survey region
is obscured, except in figure 8 of cruise 17, where the westerly flow is
clearly in evidence. Qualitatively, th& averaged dynamic heights for
cruises 20 and 21 show a southwesterly setting drift passing through the
survey region. Differences between the averaged dynamic heights in the
quadrants of the survey region for each cruise indicate that the strength
of currents during the sumnrier months (cruises 17 and 21) is approximately
twice that observed during the winter cruise.

29

Figures 9, 20, and 32 showed the relative flows of the upper
intermediate layer associated with the salinity maximum. In each
case the complex pattern obscured any net current trend. Qualitatively,
the averaged dynamic heights indicate that during cruise 17 a weak,
southwesterly current passed through the survey region with some of
the water being deflected toward the northwest and southeast along the
island chain. For cruise 20 a southeasterly drift was indicated along
the island chain, and for cruise 21 the averaged dynamic heights showed
a southerly current impinging on the inlands which was deflected toward
the southeast. The net current strength during cruises 20 and 21 was
approximately twice that of cruise 17, but in cruise 21 the direction
changed toward that observed for cruise 17. The indicated seasonal
variation in the relative drift direction of the upper intermediate layer
was a feature also noted in the surface layer.

APPENDIX
Tabulations of oceanographic data for Hugh M. Smith cruises 17, 20, 21, 26.
Personnel:

Captains:

Hugh MjSmith cruise 17 - R. Johnson
Hugh M. Smith cruise 20 - R. Johnson
Hugh M. Smith cruise 21 - G. Wilkinson
Hugh M. Smith cruise 26 - J. Sutherland

Field Party Chiefs:

Hugh M. Smith cruise 17 - J. King
Hugh M. Smith cruise 20 - T. Cromwell
Hugh M. Smith cruise 21 - E. D. Stroup
Hugh M. Smith cruise 26 - D. Yamashita

In charge of data computations and tabulations - Mrs, M. L. Godfrey

Remarks about the data tabulations:

Weather was recorded according to the WW code in the U. S.
Weather Bureau Circular M, Instructions to Marine Meteorological
Observers.

Wind velocity was measured by an anemometer located 30 m. above
the sea surface.

In the tabulated data, the horizontal line(s) between depths separates
the two or more casts necessary during the particular station.

When the interpolated and calculated values are shown for greater
depths than the observed values, they were obtained by extrapolation using
the data from adjoining stations as a guide.

Measurements of temperature, chemical determinations of salinity,
oxygen, and phosphate were made in duplicate and averaged if the values
were within the following limits: temperature, above 300 m. , 0.05 C. ,
below 300 m. , 0. 02 C. ; salinity 0. 04 °/oo; oxygen 0, 1 ml/1; phosphate
0.05 |Jig-at/l. Whenever these limits are exceeded, both values are
carried in the tabulations. Obviously wrong values, as determined from
the station curves, are omitted from the tabulations.
