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.

Note: The underlined values represent the dominant modal speeds in each case.

The sample sizes on which table 1 is based are about 50 returns in each case, exceptfor the two sets of values for distances of 100 miles or less from July to December, each of which has more than 100 returns represented in it. The

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.
