PREFACE

This is the second in a series of atlases containing hydrographic and plankton data from the region of the California Current. The field work was carried out by the California Cooperative Oceanic Fisheries Investigations,' a program supported by the Marine Research Committee of the State of California. These data were processed and are presented by the Marine Life Research Program of Scripps Institution of Oceanog- raphy, University of California, San Diego, La Jolla, California. Atlas No. 1, already issued (Anon. , 1963), contains charts of 10-meter temperatures and salinities through- out the California Current region for the years 1949 to 1959 inclusive. Future hydrographic and biological atlases on the California Current are planned and will be issued as individual units are completed.

The atlases provide processed physical, chemical and biological data plotted on standard charts which are printed one to a page. They should be considered both a source and a tool for examining this complex region in which there is mixing between several different oceanic environments. Publication of this atlas series will make the data available much sooner than if they were to await presentation in analytical reports. The series willalso permit publication of a fuller spectrumof the data. By issuing this uniformly processed information while widespread interest prevails, the atlases should I* serve to encourage more interdisciplinary studies on the oceanography of the California Current.

The CalCOFI Program undertook monthly cruises over an extensive grid of stations in the waters off California and Baja California from 1949 to 1961. A basic station plan is shown in Chart 1. It should be noted that all stations were not occupied during each cruise. At the outset the plan was to monitor and accumulate a prolonged series of observatioiis on fundamental hydrographic and biological features of the region. Such a background would then provide the context within which to examine popu- lation fluctuations of the California sardine (Sardinops caerulea) . This objective has since been expanded and the current aim of the program is to contribute to a basic understanding of the ecology of the pelagic realm.

The first step toward this objective is determination of the chemical and physical characteristics of the environment and the variety, abundance and distribution of the organisms comprising the plankton community. Hydrographic data from CalCOFI

Usually abbreviated CalCOFI, sometimes CALCOFI or CCOFI.

V cruises are systematically assembled by the Data Collection and Processing Group of Scripps Institution of Oceanography. CalCOFI plankton has been under study by a number of systematists working in their respective specialities with the Marine Life Re- search Program.

Plankton data do not attain the precision generally attributed to physical and chemical oceanographic data, because the extent to which a single plankton sample is quantitatively and qualitatively representative is a function of many uncontrolled vari- ables; e. g. , biological phenomena such as patchiness, vertical migration, grazing effects, growth, reaction to collecting gear as well as selectivity of collecting gear. Despite these adverse features, plankton samples offer information that cannot be du- plicated at present in any other fashion. At best, they comprise a remarkably sensi- tive measure of the environmentalquality of the sea water from which they were taken. In terms of terrestrial features, plankton samples from a seemingly monotonous ocean can permit identification of desert from prairie, meadow from forest, alpine heights from valley. In general they provide a cumulative index of the recent environmental history within a volume or parcel of water. Support for these claims is empirical and rests upon a persistent high degree of concordance in the distribution of physical- chemical oceanographic features and biogeographical-ecological groups of species from cruise to cruise and year to year. That is, wherever hydrographic and biological features have been monitored simultaneously for long periods of time, seasonal Am- and yearly variations in the two are usually related. Even the effects of local phenomena such as upwelling and coastal countercurrents are readily apparent in the distribution of both organisms and oceanic properties routinely measured by the CalCOFI Program.

The procedures used to analyze the plankton samples have been designed to meet the particular requirements of the taxon. They will be described by each contri- buting author in conjunction with other pertinent comments on the number of species covered in his report and the total of the group known from the California Current region.

Quantitative distributions will be shown by contouring standard contour intervals based on a logarithmic scale to the base 10. Efforts have been made to maintain a degree of uniformity in drawing the contours. The plankton distributions to be presented in these atlases are based on examination of standard CalCOFI plankton Sam- ples. 2

A standard CalCOFI tow is taken with a net 1 meter in diameter, roughly 5 meters long, constructed of 30 xxx grit gauze (heavy duty silk bolting cloth, mesh size about

vi It should be noted that biological and hydrographic samples were obtained when the ship arrived on station irrespective of time of day. Hence, the effects of diurnal vertical migration must be borne in mind, especially when considering the abundance of those species whose amplitude of migration normally exceeds the maximum depth of the tow.

Atlases dealing with plankton will also contain charts showing standard and selected hydrographic conditions prevailing at the time of the biological collections. Usually, each chart will show the distribution of one species during a single cruise. Charts will be the same in size and scale as the hydrographic charts and will be printed on one side to facilitate any combination of direct comparisons by overlay. Holes have been punched to simplify use and rearrangement in loose-leaf binders. The abbreviated legend in the lower right-handcorner of the page will help to sort the charts quickly or to select those of particular interest. Future atlases will be prepared in as similar a manner as their individual contents permit.

The net is equipped with a flow meter which allows the amount of water filtered to be calculated and is fixed to the towing wire by a short three-lead bridle preceded by a short length of line. The length of line attaches to the towing wire by awire clamp placed 3 meters above a 100-lb. hydrographic weight fixed to the end of the towing wire. The haul is taken with the ship steaming under way at 1-1/2 to 2 knots. The wire is payedout at 50 meters per minute for 4 minutes. With 200 meters of wire out (about 140 meters actual fishing depth) the net is towed at maximum depth for 1/2 minute. The net is retrieved at 20 meters per minute. During the haul the angle of the towing wire straying from the vertical is maintained as close as possible to 45" by varying ship's speed. Further discussion of the net and field tech- niques are given by Ahlstrom (1948, 1952, 1954) and King and Demond (1953).

xiv Faunis tics

Distribution charts of about one-third of the species of calanoid copepods that were collected during CalCOFI Cruises 5804 (30 March - 27 April 1958), 5807 (30 June - 22 July 1958), 5810 (8 October - 6 November 1958) and 5901 (7 - 29 January 1959) are presented in this volume. The remaining species will be dealt with in a subsequent atlas. A complete species list will be presented elsewhere together with a discussion of the fundamental types of distribution shown by calanoids in the region.

The species dealt with in this atlas are listed alphabetically in the Table of Contents. Frequently occurring forms typical of the California Current fauna as well as some relatively rarer species appear in this list. Some of the rarer species rep- resent biogeographical areas that lie adjacent to the California Current and into which this current intrudes. In the Table of Contents species not recorded previously from the Pacific Ocean east of longitude 140" W aredesignated by a dagger (+), while those appearing primarily in night tows are designated by an asterisk (*) .

Identifications are based on comparison of specimens with published descrip- tions. A number of endemic species distinguishes the boreal-temperate, epi- and -- mesopelagic copepods of the North Pacific from those of the North Atlantic. However, many other species of these faunas are known in which North Atlantic and North Pa- cific cognates are barely distinguishable, if at all, on a morphological basis. Although there may be a lack of genetic exchange between these populations at present, the dis- junct seems to be a temporary one of relatively short duration in geological time. Sev- eral of these cases have been examined (unpublished) and no evidence was found of ap- preciable, morphological divergence. These species have been identified --sensu lato and are so noted (s. 1.) in the species list in the Table of Contents.

Only a portion of the collections of the four cruises (5804, 5807, 5810, 5901) was selected for examination as described below. In response to an initial objective of surveying the calanoid fauna of the California Current region, stations were chosen: 1) to observe the assemblage of species within the maximum geographical length and breadth covered by each cruise, and 2) to monitor north-south and east-west seasonal features at regular geographic intervals. Counts were restricted to adult, sexually mature individuals because rapid identifications were more dependable and because the relatively coarse mesh of the meter net probably did not sample smaller-sized individuals quantitatively. Extended appendages and setae help retain individual copepods on the mesh but it seems certain that adults below 2.00 mm in total length are not re- tained as efficiently as larger-sized species. Hence abundance estimates are minimal, and the minima are especially low for smaller species, which are designated in the Table of Contents by a double asterisk (**) . Quantitative Analysis of Samples

Samples were routinely brought to 600 cc total combined volume of fluid and organisms (in the standard CalCOFI tow the net usually filtered from 500 to 700 m3 of 6 ocean water, thus the samples were examined in concentration of about 10 ) . All adult calanoids in a 10% sub-sample were identified and counted to obtain estimates of abundance of each species. The 10% sub-sample represents the sum of three separate aliquots of 20 cc. Each aliquot was removed, counted and returned to the original prior to removal of a subsequent aliquot. The 20 cc aliquots were taken with a piston (Stempel) pipette immediately after stirring the total sample through five clockwise rotations fol- lowed by two counterclockwise rotations, all made in fairly rapid succession.

The aliquots were counted in a plexiglass tray, 2-3/4 x 1-7/8 x 3/8 inches, internal dimensions, which was partitioned into 9 parallel channels by plexiglass walls to minimize movement of organisms during microscopic analysis. Counts were made at 16 x magnification with a stereomicroscope equipped with a mechanical stage. At this magnification the field of view spans the distance across a single channel. After completionof the aliquot counts, the entire sample was examined for species which had not appeared in the aliquots. A portion of the total sample was poured into the counting tray and scanned at 16 x magnification, this procedure being repeated until the entire rDr sample was examined. Scanning generally increased the species list by about 25%. Quantitatively, these rarer species were assumed to fall within the lowest interval of abundance used in the contouring.

Counts of individuals of a species were transformed to number per 1000 m3 of sea water filtered using the formula 10,000 n = N, V where n = number of individuals in 10% subsample,

V = number of m3 of water filtered during the tow, and 3 N = number of individuals in 1000 m filtered.

Copies of the actual counts are on file in the Library and with the Marine Life Research Program Director, Scripps Institution of Oceanography, La Jolla, California.

The author wishes to express his gratitude to Miss F. M. Fischer of the Cal- COFI Atlas staff, for the overall excellence of the plotting and drafting of the biological charts. The analyses for the physical data charts were made by Mr. John G. Wyllie,

These maps are designed to show essential details of the area most intensively studied by the California Cooperative Oceanic Fisheries Investigations. This is approximately the same area as is shown in color on the front cover. Geographical place names are those most commonly used in the various publications emerging from the research. The cardinal station lines extending southwestward from the coast are shown. They are 120 miles apart. Additional lines are uti- lized as needed and can be as closely spaced as 12 miles apart and still have individual numbers. The stations along the lines are Rum- bered with respect to the station 60 line, the numbers increasing to the west and decreasing to the east. Most of them are 40 miles apart, and are numbered in groups of 10. This permits adding stations as close as 4 miles apart as needed. An example of the usual identification is 120.65. This station is on line 120, 20 nautical miles south- west of station 60. The projection of the front cover is Lambert's Azimuthal Equal Area Projection. The detail maps are a Mercator projection.
