Created In 1849, the Department of the Interior— a department of conservation— is concerned with the
management, conservation, and development of the Nation's water, fish, wildlife, mineral, forest, and park
and recreational resources. It also has major responsibilities for Indian and Territorial affairs.

As the Nation's principal conservation agency, the Department works to assure that nonrenewable
resources are developed and used wisely, that park and recreational resources are conserved for the future,
and that renewable resources make their full contribution to the progress, prosperity, and security of the
United States-now and In the future.

ABSTRACT

Since January 1961, the Bureau of Commercial Fisheries Biological Laboratory in Honolulu has
been releasing drift bottles and cards in the central Pacific Ocean. Data are presented on all
releases and recoveries through June 1963, together with charts showing the release and recovery
points. An analysis of the returns from the Hawaiian Islands shows that there is a seasonal change
in the direction and speed of the current system near the Islands which coincides with changes in
strength of the trade wind system. During the first half of the year the current moves at speeds of
between 6 and 11 nautical miles per day and near Oahu and Kauai it moves toward the northwest,
while in the latter half of the year the speed is 6 nautical miles per day or less, and the direction of
flow is toward the west or somewhat south of west.

INTRODUCTION

In 1961 the Bureau of Commercial Fisheries
Biological Laboratory in Honolulu began a series
of drift bottle releases designed primarily to
obtain more complete and detailed information
on the currents near the Hawaiian Islands than
was then available. It was clear that such infor-
mation was required in order to interpret vari-
ous kinds of oceanographic and tifological infor-
mation collected by the Laboratory near the
Islands, and drift bottle techniques offered a
means for obtaining considerable information
in an economical way, preliminary to the use
of more sophisticated and expensive procedures.

At that time, the information on surface and
near-surface currents near the Hawaiian Islands
consisted primarily of oceanographic station data
taken by the Laboratory a decade earlier (Mc-
Gary, 1955; Seckel, 1955), together with data on
surface drift obtained from ship's log books
(H. O. Publication nos. 570, 1947; and 569, 1950).

The dynamic topography of the sea surface
near the Hawaiian Islands (McGary, 1955; Seckel,
1955) is characterized by an irregular series of
eddies which vary considerably in size, number,
and location. The eddies tend to obscure the pat-
terns of mean flow, and because little is known
about the growth and decay of such eddies, or of
their movements, the information on mass trans-
port which can be derived from the dynamic
topography is valid for intervals of time of the
order of a few days only.

Current charts based on ship's drift provide
information on a monthly basis, and thus offer
some continuity in time. However, the data are
averaged over a number of years and over areas
of 1 degree of latitude and longitude, so that the
details of currents on a scale comparable to that
of the individual islands are lost, since even
Hawaii, the largest of the islands, is less than
60 nautical miles in mean diameter.

DESCRIPTION OF BOTTLES
AND CARDS

Drift bottles were used initially, but were
gradually replaced by drift cards during 1961.
The drift bottle consisted of an 8-ounce clear
glass bottle, ballasted with sand so that an inch
of the neck protruded above the water (fig. 1).
Cards were enclosed which contained Instruc-
tions to the finder in English, Spanish, and
Japanese, with a postcard attached which could
be torn off for mailing (fig. 1). The postcards
were numbered, postage paid, and self-addressed
with blank spaces for the name and address of
the finder and the time and place of recovery.
The back of the card was printed with wide Inter-
national Orange stripes to catch attention. These
cards were folded up and wrapped once with
pressure-sensitive tape to facilitate insertion in
the bottle and to permit the finder to remove the
card easily. The bottles were sealed with waxed
corks.

In 1962 some experiments with drift cards
sealed in plastic envelopes showed that the cards
performed as well as the bottles and were much
more convenient to store and use. The drift card
consisted of a numbered, bright red postcard
similar to that used in the bottles, but with the
instructions to the finder printed on the back of
the card (fig. 2). A weight was enclosed to make
the card float vertically in the water so that its

movements, like those of the bottles, would
depend primarily on the currents in the upper-
most 6 inches of the water column. The drift
cards were sealed in polyethylene bags and then
packaged in flimsy waxed-paper bags, in groups
of 20, to ensure control of the serial number
sequence and the number of cards per release;
the waxed-paper bags were selected for their
ability to come apart in the water in a minimum
time, usually about 2 to 3 minutes.

The costper bottle was estimated at 10 cents;
the drift cards cost 11 cents each.

NEW DRIFT CARD DESIGN

with experience in the manufacture and use
of the drift cards described above, it became
apparent that considerable Improvement in the
design was possible. Although none of the data
presented herein were obtained with the new type
of drift card, the new card will be illustrated and
its manufacture briefly described because it
represents a significant improvement in design
which may be of value to others who are consid-
ering the use of drift cards.

which is inserted a length of soda straw cut to
fit the width of the bag. When the upper compart-
ment is sealed, the card is finished and ready
to be placed in its waxed-paper bag with 19 other
cards. All cards of this design floated upright
without tilting, with a waterllne at a level with
the soda straw, exposing a uniform half-inch of
the upper edge above water. The cost per card
Is 14 cents in quantity lots.

Figure 3. — New drift card design.

The important characteristics of the design
(fig. 3) are:

1. A strip of metal ballast whose center of
gravity is always near the long axis of the card,
so that the card does not tend to float with one
corner higher than the other , presenting an unbal-
anced area to the wind.

2. The absence of significant amounts of air
in the card's compartment, so that the buoyancy
can be concentrated at the end opposite the bal-
lasted edge.

Drift bottles, and later drift cards or cards
and bottles together, were released whenever
feasible by the Laboratory's research ship, the
Charles H. Gilbert, beginning with cruise 51 in
January 1961. In addition, the U. S. Coast and
Geodetic Survey ship Surveyor released almost
3,000 cards during two cruises early in 1963,
when that ship was working to the north of Mid-
way Island, and a few bottles were released near
Oahu in September 1961 by the M/V Broadbill.
a fishing vessel then under charter to the Labora-
tory.

The releases are listed in the Appendix,
which shows the cruise number (except In the
cases of the Surveyor and Broadbill releases),
the sequence number of the release, the number
of bottles and/or cards In each release, and the
date and location of the release. Initially there
were 10 bottles In each release, but this number
was later Increased to 20 to improve the chances
of multiple recoveries. On various occasions
the number of bottles or cards per release were
modified, and these exceptions are also noted in
the tables.

The Appendix also shows the number of re-
coveries, if any, per release, as well as the date
of each reported return, and the location where
the bottle or card was found.

3. A controlled volume of air in a separate
compartment of the plastic envelope, which vir-
tually eliminates the possibility of sinking or of
exposing too much area to the winds.

These cards are manufactured by placing
the card and metal ballast strip in a polyethylene
bagof 6-mil thickness, squeezingthe card-filled
portion between spring-loaded metal plates to
remove the air, and sealing the upper edge of
the card compartment. This leaves a 1-inch
pocket at the upper end of the plastic bag, into

No reward was offered for reporting returns.
The finder was sent a letter which thanked him
for his assistance and outlined the project objec-
tives, which told him when and where the bottle
or card which he found had been released, and
which also contained information on the minimum
speed and the distance covered. Enclosed with
each such letter was a chart showing the release
point and the presumed path of the bottle or card,
as well as the postcard mailed by the finder in
reporting the recovery.

RESULTS

From January 1961 to June 1963, a total of
16,285 bottles and cards were released, and by
January 1964 a total of 538 returns had been re-
ported. This represents a recovery rate of 3.3
percent, which is remarkably high considering
the ratio of the area covered by releases to the
coastline available in the mid-Pacific. It can be
compared, for example, with the return rate of
4.6 percent reported by Schwartzlose (1963) for
releases off southern California.

On the island of Oahu, where some 80 percent
of the population of the State of Hawaii lives, the
timing of returns suggests that almost no bottles
or cards remain undetected on landfor more than
about 1 day, which considerably enhances the
reliability of the minimum velocities which can
be computed from the time the drift bottle or
cards spent in the water and the minimum dis-
tance covered. These minimum velocities range
from less than 1 mile per day to about 15 miles
per day, but within this range there are fairly
distinct groups of speeds which appear to be
characteristic of seasonal current patterns and
of the distance traveled by the drift bottle or
card. For returns to the islands of Oahu and
Kauai, which represent the largest samples, the
frequency distribution of computed minimum
velocities shows modes at speeds of about 10
miles per day, 6 miles per day, 3 miles per day,
and less than 1 mile per day. Table 1 shows the
relationship between these characteristic modes
in the velocity spectrum and the time of year
and the distance traversed.

49 returns from distances greater than 100
miles were not enough to permit breakdown by
time of year.

The choice of time periods in table lis based
on a distinct seasonal pattern in the direction of
travel of the drift bottles and cards. Figures 4
through 9 show the locations of releases and re-
coveries, together with the inferred trajectories.
The data are grouped by season, except for the
period from April to June, where it was possible
to chart returns by month. Figure 10 shows the
returns from releases outside of the immediate
vicinity of the Hawaiian Islands. All releases
are shown in figures 4 through 10 as dots; re-
leases with returns have trajectories associated
with them. In cases where more than one return
resulted from a release, only one trajectory is
shown, unless the recovery points were relatively
widely separated. Trajectories were drawn
using the convention that trajectories from near-
simultaneous releases cannot cross; Inflgure 10,
the trajectories were drawn with the aid of the
Atlas of Surface Currents (H. O. Publication
no. 570, 1947).

During Charles H. Gilbert cruises 58 and 63,
in July 1962 and January to March 1963, respec-
tively, bothdrift bottles and cards were released
simultaneously. This was part of a series of
tests to determine the relative effectiveness of
the two packages. Essentially the same propor-
tions of both bottles and cards were reported
found, and there was no significant difference in
the directions of movement, so that the two pack-
ages were considered equivalent in performance.

The sample sizes on which table 1 is based

DISCUSSION

The velocity figures shown in table 1 suggest
a seasonal change in the velocity of the North
Pacific Equatorial Current in the latitude of the
Hawaiian Islands. In the early part of the year
there was little evidence of speeds of drift of
more than 6 nautical miles per day; later in the
year, and particularly in returns from more
than 10 nautical miles away, there was a consid-
erable proportion of returns with minimum ve-
locities of from 9 to 11 nautical miles per day.

This change in speed coincides with a change
in the direction of drift. Figures 4 through 6
show that most recoveries during the first half
of the year came from releases made to the south
of the recovery points, so that the bottles and
cards must have been carried north through the
inter-island channels before coming ashore on
the windward (northeast) coasts 'of the Islands.
Figures 7 and 8, on the other hand, show a much

greater proportion of returns from releases to
the east. Thus, a change in the angle of incidence
of the current relatively near shore must take
place about June; before then, the drift is roughly
parallel to the Islands, with a considerable north-
ward component, while later in the year the flow
is primarily from the east or northeast. The
evidence for this change is particularly clear
when figure 4 is compared with figures 7 and 8,
because the periods represented on these charts
all contain releases made northeast of the Islands.

As might be expected, the change In the speed
and direction of drift with time of year coincides
in a general way with the changes In the North
Pacific trade wind system. In October through
April the windspeeds are lower and light, vari-
able winds are more frequent than in May through
September, when the winds exceed 14 miles per
hour 50 percent of the time, and 80 to 95 percent
of the time are from the northeast quadrant
(Blumenstock, 1961).

SUMMARY

LITERATURE CITED

1. From January 1961 through June 1963, a
total of 16,285 drift bottles and cards were re-
leased in the central and western Pacific Ocean,
the majority in the vicinity of the Hawaiian
Islands.

2. By January 196-4 there had been 538 re-
turns.

3. The pattern of recoveries from the Hawai-
ian Islands suggests that the current system near
the Islands varies seasonally in strength, with
velocities during May to September of about 6 to
11 nautical miles per day, and 6 nautical miles
per day or less during October to April, as com-
puted from minimum speeds of drift of both
bottles and cards.

4. The pattern of recoveries also suggests a
seasonal change in the direction of drift In the
immediate vicinity of Oahu; from January to May
the drift was predominantly to the northwest,
roughly parallel to the Island chain, while dur-
ing June to December the drift was primarily to
the west or somewhat south of west.

5. In general, the pattern of surface drift,
and its speed, coincide with the seasonal changes
in strength of the trade wind system.
