Preface Oceanic Observations of the Pacific is a medium for publication of oceanographic data collected in the Pacific Ocean and its adjacent seas by the cooperating agencies. At the present time these agencies are Scripps Institution of Oceanography of the University of California, San Diego, California; Biological Laboratory of the Bureau of Commercial Fisheries, Honolulu, Hawaii (formerly Pacific Oceanic Fishery Investigations); Biological Laboratory of the Bureau of Commercial Fisheries, La Jolla, California (formerly South Pacific Fishery Investigations); Biological Laboratory of the Bureau of Commercial Fisheries, Seattle, Washington (formerly Pacific Salmon Investigations) ; Department of Oceanography of the University of Washington, Seattle, Washington; InterAmerican Tropical Tuna Commission, La Jolla, California; Pacific Oceanographic Group of the Fisheries Research Board of Canada, Nanaimo, British Columbia; United States Navy Electronics Laboratory, San Diego, California. Certain cruises were carried out jointly as California Cooperative Oceanic Fisheries Investigations (CCOFI). The agencies cooperating in the CCOFI program are the Scripps Institution, the Biological Laboratory of the Bureau of Commercial Fisheries, La Jolla, the California Department of Fish and Game, the Hopkins Marine Station and the California Academy of Sciences. A grant from the National Science Foundation has supported part of the cost of preparing these data for publication and most of the printing cost. The present volume contains observations made in 1952. For each oceanographic station, values of temperature, salinity and oxygen are tabulated at observed and at standard depths. Computed values of density, specific volume anomaly or thermosteric anomaly, and geopotential anomaly are also tabulated at standard depths. In addition, some observations of phosphate and silicate are included. The positions of serial observations and the numbers of bathythermograph observations made in 1952 and during the period 1941 through 1952 are shown on charts. Information concerning each cruise is summarized in a table.

Description of Observations SIGNIFICANCE OF REPORTED OCEANOGRAPHIC DATA

several months and evaporation occurred before titration. The extent of evaporation has been estimated by comparing the results of these two cruises with earlier and later data in the depth range of 500 to 1000 meters, and also a comparison was made of the IOmeter samples titrated immediately at the end of each cruise with the corresponding surface samples titrated much later. These comparisons show evaporation from nearly all samples. The mean of the resulting change of salinity was 0.0431 for the RV Horizon data and 0.060)1. for the RV Crest data. However, evaporation was not uniform since depth-by-depth and station-by- station differences from the more dependable data varied somewhat. For the Horizon the standard deviation was 0.0791 and for the Crest it was 0.0141.

Routine field measurements of océanographie parameters by conventional methods are usually subject to at least the following random errors: depth

14 m (in the upper 1000 m)

temperature

±0.02*C

salinity

10.031

oxygen

±0.04 ml/L

phosphate

10.05 to 0.1 ug at/L All salinity values of these two ships, except the IOmeter data, are marked "E," indicating that evaporation is known to have occurred.

A recent analysis of the precision of field measurements of temperature and salinity is that of Wooster and Taft (1958). It should be noted that the above estimate of salinity precision refers to analyses by Knudsen titration.

On Cruises 5201 through 5210 salinity samples were titrated manually; on Cruise 5211 salinities were obtained by an automatic device which determined the end point by measuring the electrical potential. The random e r r o r s in the manual method are estimated to be about 0.0251 (root mean square); those of the automatic device, about 0.0501.

Interpolated values at standard depths are known with less precision, and the resulting uncertainty in specific volume anomaly and thermosteric anomaly at standard depths due to random e r r o r s in field measurements of temperature, salinity and depth is of the order of three centiliters per ton. Therefore, in this publication series it is the practice to report specific volume anomaly and thermosteric anomaly to no more than one part in 105 (one cl/ton) andgeopotentlal anomaly to no more than the nearest dynamic centimeter.

Expedition Shellback The purpose of Shellback and associated Expeditions Shuttle and Shortcut (Operation Co-op) was to obtain an extensive and systematic set of oceanographic observations from the eastern tropical Pacific. Prior to 1952 only a few observations were available from this area.

It should be noted also that computations of salinity (from measured chlorinity) and density (sigma-t, specific volume anomaly and thermosteric anomaly) r e ported in this volume have all been based on the empirical equations and tables by Knudsen (1901) and Ekman(1908). Because of the inadequacy of our present knowledge of the equation of state of sea water (Eckart, 1958) and the uncertainty of the relationship between chlorinity and salinity (Carrltt and Carpenter, 1959), it is possible that these computed values differ systematically from the absolute values. However, in the upper thousand meters at least, Reid (1959) has shown that the influence of such systematic e r r o r s on the accuracy of computed geostrophic flow is significantly smaller than the Influence of e r r o r s in the determination of temperature, salinity, pressure and position.

After return of the expedition it was discovered that the salinity bottles had not been adequately sealed. Analyses of the samples showed numerous abnormally high salinity values, indicating that evaporation had occurred. Because of the random nature of this evaporation and because a large percentage of the samples was affected, it was decided to discard all of the salinity values. Expedition Capricorn Expedition Capricorn was the fourth of a series of oceanographic expeditions into the deep Pacific sponsored by the Navy Department and the University of California. Most of the work was done between the equator and the Tropic of Capricorn; hence the name, Capricorn. The principal aim of the expedition was to study the floor of the deep Pacific basin.

NOTES ON PARTICULAR CRUISES California Cooperative Oceanic Fisheries Investigations

In addition to geological and geophysical exploration, certain biological, physical and meteorological observations were made because the sediment blanket is so closely interwoven with the life and movement of the water above the sea floor and, also, the movement of ocean water is affected by the atmosphere above the sea.

It has been found that on the first cruise of 1952(CCOFI 5201) nearly all of the salinity data obtained by two ships are subject to substantial e r r o r . The water samples were stored with unsatisfactory seals for

Cruises HMS-14, HMS-15, HMS-16 and HMS-17

Expedition Shuttle

No correction of depths for the four cruises of the RV Hugh M. Smith presented in this volume has been necessary since no error was made in the original computations at the time of processing. (An error reported by ThomasS. Austin, 1962,had been made in the calculation of later data of the EV Hugh M. Smith and RV Charles H. Gilbert reported in Special Scientific Reports, U.S. Fish and Wildlife Service, Fisheries Nos. 168, 180, 201, 217, 238, 252, 315, 358 and part of 164.)

The USS Marysville of the U. S. Navy Electronics Laboratory made observations in the eastern tropical Pacific on Expedition Siuttle as part of Operation Coop. The final processing of the data was done by the Data Collecting and Processing Group of the Scripps Institution. Cruises BB-1, BB-4, BB-7 and BB-9 Interpolation of values at standard depths was performed by the IBM Type 650 Magnetic-Drum DataProcessing Machine in the Research Computer Laboratory of the University of Washington, using the three-point Lagrange curve based upon one point above and two points below the desired depth. Corrections were made for any peculiar interpolations which resulted from use of this method in the upper layers.

Cruise NP-52-1 Interpolation for values at standard depths and determination of calculated depths were carried out by machine program at the U. S. Naval Oceanographic Office, Washington, D. C. Interpolations were made by the three-point Lagrange method (U. S. N. Hydrogr. Off., 1960; Nat. Oceanogr. Data Center, 1962).

General Methods Unless otherwise indicated, subsurface temperature by paired protected reversing thermometers; salinity by Knudsen method; dissolved oxygen by Winkler method aboard ship; inorganic phosphate analyses by the molybdenum-blue method (Wooster and Rakestraw, 1951). When available, specific information on accuracy is indicated by footnotes. Absence of such information does not necessarily imply that the nominal accuracies have been achieved.

CCOFI a CCOFI thermometer calibrations indicate the temperature accuracy to be 0.02°C; field tests indicate a salinity accuracy of ± 0.025&(root mean square). This accuracy was achieved on Cruises 5201 through 5210, but the root mean square was estimated to be ± 0.050%> for Cruise 5211. See Notes on Particular Cruises for information concerning methods of titration on Cruises 5201-5211 and evaporation on Cruise 5201. b Oblique plankton tow to approximately 140 m (200 m of wire out, or less in shallow water) taken with a 30XXX net, 1.0 m in diameter at mouth by approximately 5 m in over-all length with detachable cod end of 56XXX nylon grit gauze, c Half-hourly lowerlngs between station lines along the coast. d Oblique plankton tow to approximately 424 m (600 m of wire out, or less in shallow water) taken with a 30XXX net, 1.0 m in diameter at mouth by approximately 5 m In over-all length with detachable cod end of 56XXX nylon grit gauze, e Half-hourly lowerlngs between station lines along the coast and hourly between stations on the station lines. f One oblique plankton tow to approximately 42 m (60 m of wire out) and one to approximately 98 m (140 m of wire out) taken with a 30XXX net, 1 . 0 m in diameter at mouth by approximately 5 m in over-all length with detachable cod end of 56XXX nylon grit gauze, g Half-hourly lowerlngs between station lines along the coast and hourly between stations on station lines except when net tows were made between hydrographicstations.
