THE CALCOFI ATLAS SERIES This is the fifteenth in a series of atlases containing data on the hydrography and plankton from the
region of the California Current. The field work was carried out by the California Cooperative Oceanic Fish- eries Investigations,l a program sponsored by the State of California under the direction of the State’s Marine Research Committee. The cooperating agencies in the program are:
California Academy of Sciences California Department of Fish and Game Stanford University, Hopkins Marine Station National Oceanic and Atmospheric Administration, National Marine Fisheries Service* University of California, Scripps Institution of Oceanography
CalCOFI atlases3 are issued as individual units as they become available. They provide processed physical, chemical and biological measurements of the California Current region. Each number may contain one or more contributions. A general description of the CalCOFI program with its objectives appears in the preface of Atlas No. 2.
This atlas was prepared by the Data Collection and Processing Group of the Marine Life Research Program, Scripps Institution of Oceanography.

10-METER TEMPERATURE A N D SALINITY
Charts of the temperature and salinity dis- tribution at 10-meters depth for individual Cal- COFI cruises are presented for the years 1960 through 1969. These charts continue the 11- year (1949 to 1959) series presented in Cal- COFI Atlas No. l (Anon., 1963). The presen- tation used in Atlas No. 1 has been retained. The distributions by month are graphically sum- marized on Charts 2 and 3.
The 10-meter depth level has been used
throughout the CalCOFI program as represent- ative of the surface layer. It was chosen in preference to the sea surface in order to avoid shallow transient conditions.
10-meter Temperature Time Series The temperature and temperature anomaly
time series for selected stations given in Atlas No. 1 are continued in this atlas through 1969 for the same stations. No new monthly mean temperatures have been computed ; the monthly means based on the data for 1950 through 1959 have been retained as the reference for com- putations of anomalies. Selection of the stations used in the time series was based upon the number and the time distribution of the meas- urements available for a given station. Sam- pling was approximately monthly during 1960, 1966 and 1969; observed values within these years are connected by a solid line. The years 1961 through 1965 were sampled quarterly; these observed values are connected by a heavy dashed line. The years 1967 and 1968 were infrequently sampled; these observed values are connected by light dashed lines. Positive anomalies from the 1950 to 1959 mean are shown as grey bars and negative anomalies as black bars.
150-METER MONTHLY MEANS A series of monthly mean distribution
charts of temperature, salinity and oxygen at a depth of 150 meters is presented on Charts 132 to 167. The 150-meter level was chosen because it is the standard oceanographic level nearest the maximum depth (140 meters) fished by the standard CalCOFI zooplankton net. The distribution of properties at 150 meters of depth is, therefore, very nearly that which is encoun- tered at the maximum depth of the zooplankton net tow routinely taken at CalCOFI stations.
All available CalCOFI data for the 150-
V
meter level in the years 1950 through 1968 were used in the preparation of the charts. The data were obtained from the National Oceano- graphic Data Center, Oceanic Observations of the Pacific (1950-1959) and the Physical and Chemical Data Report series for the years 1960 to 1968, the last two sources being issued by the University of California, Scripps Institution of Oceanography. The 150-meter means also include measurements obtained from acceptable hydrographic bottle casts which malfunctioned and casts requiring extrapolations to the 150- meter level that are not included in the Na- tional Oceanographic Data Center files.
Method of Analysis The monthly mean values were computed
by the method of harmonic analysis as given by Lynn (1967). Briefly, the method groups all data from the time series of each station into one 365-day period; i.e., only the month and the day of sampling are considered. A curve formed by the annual and semi-annual harmonics is then fitted to the observations by the method of least squares regression. Monthly means are obtained by selecting mid-month values from the resulting curve; these values were plotted and contoured.
This method of analysis is preferred over computation of arithmetic monthly means be-

cause it interpolates in time and thus provides a good estimate for months that were infre- quently sampled.
The 19-year Mean and the Standard Error of Estimate
The statistical analysis also furnished an overall mean for the years 1950 through 1968; the contoured distribution of these 19-year means are given in three charts, one each for temperature, salinity and oxygen. The residuals between the fitted curve and the individual datum values are used to compute the standard error of estimate about the curve; the contoured distributions of standard error of estimate, one each for temperature, salinity and oxygen, are presented. Observed temperature records and the fitted curves for two sample stations, 60.60 and 110.80, are plotted in Figure 1. The dashed lines are drawn at plus and minus one standard error of estimate. The regression curve for Sta- tion 60.60 provides a reasonable fit to the data. For Station 110.80 the dispersion about the mean is very large and there is no discernible seasonal variation; the resulting curve varies little from the overall mean. In general, only near-shore stations reveal significant seasonal variation. The 150-meter level intersects the thermocline in most offshore stations and this produces the large dispersion seen, for ex-

Station regression curves and observations. Horizontal lines are 19-year means. Dashed lines are
ru
c
ample, at Station 110.80. The intersection of the main portion of the thermocline with the 150-meter level is seen as a large lateral gradi- ent in the 150-meter temperature charts.
Arithmetic monthly means were calculated for stations lacking adequate data for harmonic analysis. The contours about these points are dashed.
CONDITIONS BETWEEN T H E SEA SURFACE A N D 150 METERS
The charts described above characterize con- ditions in the California Current region at the uppermost and lowermost portions of the stan- dard CalCOFI zooplankton tow. Standard tows have been made systematically by participating agencies of the CalCOFI program beginning in 1949 and continuing to the present (Smith, 1971). Since 1950 they have been routinely collected at every occupied hydrographic sta- tion by oblique hauls between the surface and 140 meters of depth. A large number of the CalCOFI atlases has been concerned with studies based on this extensive time series of zooplankton samples.
When considering distributional features of the zooplankton in the context of the hydro- graphic climate it is useful to have estimates of surface layer thickness at sampling localities and a summary of prevalent conditions between
vii
the surface layer and the bottom of the tow. The charts and figures discussed below charac- terize these two features.
Mean Surface-layer Depth The mean surface-layer depth is presented
in a set of monthly charts (Charts 177 to 188). Surface-layer depth is defined here as the depth at which the temperature differs from that at the sea surface by more than 2OF ( l . l°C). Thus, the temperature found at 10 meters is representative throughout the layer whose mean thickness is given by these charts. The data were derived primarily from bathythermograph traces.'
Vertical Distribution of Temperature, Salinity and Oxygen
Figures 2, 3 and 4 present the vertical dis- tributions of temperature, salinity and oxygen in the upper 300 meters for CalCOFI Lines 60, 90, 110, and 130. The means for these sections were calculated from a representative portion of the available data and are included in order to show the general conditions in the region. These sections indicate, for example, features through which the zooplankton nets are towed: the thermocline, the salinity minimum and the large gradients of oxygen concentration. 1The concept of, and data for, the surface-layer depth were provided by M. K. Robinson, Head BT Analysis and Proc- essing Section, Scripps Institution of Oceanography.

These maps a r e 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 a re those most commonly used in the various publications emerging from the re- search. The cardinal station lines extending southwestward from the coast a r e shown. Additional lines a re uti- lized a s needed and can be as closely spaced as 12 miles apart and still have individual numbers. The stations along the lines a re num- bered with respect to the station 60 line, the numbers increasing to the west and decreasing to the east. Most of them a re 40 miles apart, and a re numbered in groups of 10. This permits adding stations as close as 4 miles apart as needed. An example of the usual identifica- tion 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.
They a re 120 miles apart.
The detail maps a re a Mercator projection.
