El NiGo of 1982-83

In the course of monthly aerial surveys of the distribution of marine mammals and 

birds, remotely sensed observations of sea surface temperature (S.S.T.) were made 

along the California coast between Pt. The 

close spacing and high frequency of these observations make them unique.') In 

addition, the survey series runs prior to and during the beginning of the recent and 

extensive El Ni6o event. In recognition of these factors, attendees at the 1982 

EPOC (Eastern Pacific Oceanic Conference) requested that an atlas of the survey 

data be prepared in a timely manner so that the oceanographic community might 

be made aware of the data and have access to them. The involvement of the 

P.E.G. (Pacific Environmental Group) was motivated by possibilities of using wind 

observations recorded with the temperature data to define the offshore structure 

of the wind field on a scale smaller than was possible heretofore. This is of 

interest because the wind affects upwelling and surface convergence patterns. 

Observational precision unfortunately was found to be inadequate for that purpose. 

Conception and the Oregon border. 

ACI<NO WLEDGMENTS: 

The surveys were funded by a contract to the 1Jniversity of California Santa Cruz 

(UCSC) by the Marine Minerals Management Service. Tom Dohl and his survey and 

analysis group collected the data and supplied a copy of their data tape. Craig 

Nelson and Douglas McLain adapted plotting routines that generated the individual 

charts. Ken Raymond and Roy Allen drafted the final charts. Craig Nelson, 

Gunter Seckel and Tom Dohl reviewed the manuscript. The assistance of all the 

above is gratefully acknowledged.

. 

THE DATA: 

There were two series of aerial surveys: high altitude surveys (100-series) flown at 

approximately 1000 ft ASL (above sea level), and low altitude surveys (200-series) 

flown at about 200 ft ASL. Each series had one flight per month; the high altitude 

surveys starting in March 1980 (number 1011, and the low altitude surveys starting 

in February 1980 (number 201). The 

transect lines are illustrated in Figure 1. Not all lines were flown in any single 

survey. The aircraft followed east-west oriented transect lines, which were 

selected from the 92-line series in an attempt to systematically and uniformly 

cover the entire study area. The choice of lines flown on any one survey was 

sufficient to achieve a coverage of 66% of the total number of lines. 

The surveys concluded in February 1983. 

Data collection procedures for the surveys are covered in Dohl, et al. (1983). 

Temperature readings were obtained from a Barnes PRT-5 precision airborne 

radiometer either visually from an analog meter or from a strip-chart recording. 

Locations of the readings were noted by reference to a repeater of a GNS-500 VLF 

precision navigation system. The temperature and ancillary position data were 

subsequently transferred to computer tape, a copy of which was sent to the author. 

These data were processed in conjunction with plotting and mapping 

developed at P.E.G. The resulting monthly charts were hand contoured. 

The surveys were designed to investigate distribution patterns of b 

routines 

rds and 

mammals, and were not concerned primarily with precise measurement of environmental factors such as temperature. Some attention was given to "Calibration" of temperature observations, but this effort was secondary to the principal 

survey objectives. Radiometer data were not collected on all survey flights due to 

various operational factors. The series of charts in this atlas provides the available 

time sequence of data. A limitation of unknown magnitude regarding the interchart comparability of charts prepared from data sensed at different altitudes and 

over different temperature scales may be present due to the influence of the 

amount of atmosphere through which the sensor viewed the sea surface. 

Attempts were made by the UCSC Survey group early in the survey series to 

compare radiometer readings with temperatures obtained from moored data buoys 

in the area. The flight lines selected did not 

always include a buoy location. Fog and other weather conditions at tirnes made 

They found this to be impractical.

overflights of the buoys impossible. Questions arose as to the comparability of 

buoy "surface temperature" readings due to varying depths (one to four meters) at 

which "surface temperature" sensors were placed. Therefore, they decided to 

abandon this approach. 

The data used to generate the plots are "raw" and no corrections have been applied. 

Accuracy of the data is not known for a number of reasons: 1) The instrument drift 

of the PRT-5 is not known. 2) Some data were discarded by the survey group due 

to wide variance from recent (e.g. "yesterday's") values, often due to PRT-5 

internal battery malfunction. 3) The visual temperature read-out of the PRT-5 is a 

multiple-range scale. There were some differences between data recorded from 

the two scales of the radiometer. The "low" scale range is from -20' to 15OC; the 

"medium" scale is from 10' to 45OC. When readings were below 10°C, the low 

scale was used. The medium scale is most reliable and usually was the one in use 

(Ken Briggs, UCSC, personal communication), but at times of low temperature 

conditions it was necessary to shift to the low scale. After January, 1982, data 

were taken from a digital readout of millivolts, then converted to temperatures. 

This was considered more reliable than the analog meter on the original unit, which 

was subject to vibration and oscillation due to aircraft motion. 

In-flight comparisons of radiometer readings of an on-board reference were made 

with readings of a "true thermometer". The difference (PRT minus "true 

thermometer") ranged from -4.5' to 4.l0C. For 305 comparisons the mean 

difference was 1.2OC; standard deviation and variance were l.O°C. For the 

convenience of readers who may wish to use or interpret the data or charts, the 

temperature comparison data are listed in Annex 1. 

As is apparent from Table 1, a complete monthly sequence of charts is not 

available, primarily due to weather and operational limitations. In addition, data 

were too sparse in some months and in some areas to rnake contouring possible. All 

monthly surveys with data sufficient to be useful are represented in charts of 

contoured SST's. More than one chart for a month is available in a number of 

cases. These are included because some readers may wish to compare features of 

thermal distribution over shorter times or read from the radiometer at different 

read-out scales or taken from different altitudes. Contours were drawn by hand 

and some subjectivity was exercised to smooth the lines. Discrepancies occurred

such cases the contouring shows a break or discontinuity. Temparature values are 

not printed at the observation points because their spacing is too close for 

legibility. 

INTER-YEAK COMPARISONS AMONG SELECTED MONTHS WITH RESPECT TO 

THE 1982 EL NINU EVENT. 

Because of wide-spread interest in the warm water event (El Nifio) of 1982-83, a 

brief inter-year comparison is presented for a portion of the data in this series for 

the months including the usual period of maximum seasonal warming, (AugustSeptember-October). The nine pertinent monthly charts from the atlas series are 

repeated in this section with shading of selected contours to emphasize the 

temperature changes. These are reduced for convenience here; the full-size charts 

in the atlas series may be referenced for details. Stippled areas indicate 

temperatures 14OC or less and hatched areas indicate 16OC or higher. 

The usual situation: 

During the three month period of August to October, the overall pattern of 

isotherms within the surveyed area is meridional. This is "usual" for the season 

(Sund, 1982) and there are two basic regimes present: (1) A meridional inshore 

coastal strip, influenced by cool upwelled waters which is separated by a thermal 

gradient from (2) warmer oceanic offshore waters. Inter-year variability can be 

expected in the degree of upwelling. The offshore extent of cool coastal waters-- 

i.e., the width of the coastal cool water area--is due to its spreading offshore. 

Conversely, the shoreward movement of offshore waters is due to onshore winds 

and/or lack of upwelling and related processes and advection, or due to the 

intensity of seasonal warming. 

For the area between San Francisco Bay (38'N) and Trinidad Head (41°N), peak 

warming of the offshore water occurs in September with highest SST's appearing 

closest to the coast. The greatest SST gradients exist at that time off cold 

upwelling centers such as Cape Mendocino. The nearshore SST's are approximately 

13OC and the highest offshore values are over 18'~. By October the upwelling 

processes are relaxed and winter storms begin to disrupt the established structure. 

The isotherms offshore begin to return to more southern latitudes and re-align 

zonally. Overall, the structure along the coast becomes less organized.

Comparison by month for the years 1980, 1981, 1982: 

0 

August: (Figures 2, 3, 4) 

*Warm water intrusions from offshore (16-19OC) appeared on the north and south 

sides of cold upwelled water off Cape Mendocino in 1981 and 1982 . Temperatures 

for these areas in 1980 were 11 to 12OC. 

*Upwelling in 1980 in the vicinity of Cape Mendocino evidently was stronger than 

in 1981 and 1982 because: 1) the plume at the surface in 1980 was less than 10°C, 

whereas it was over 12'C (up to 15) in the latter two years; OR 2) warmer waters 

overall were present in the two latter years and thus warmer waters were upwelled 

in those years. 

*A cool (12 - 14OC) coastal strip extended from Cape Mendocino (40°N) south to 

Point Reyes (38'N) in all years. The gradient to warmer offshore temperatures 

was greatest in 1982. 

*An upwelling plume was present off Pt. Sur (36.5'N). Again the strongest 

gradient was in 1982 

*The warm offshore intrusion off Pt. Buchon (35'N) was closer to the coast in 1980 

and 1982 and warmest in 1981. 

September: (Figures 5, 6, 7) 

*In 1981 and 1982 (sparse data in 1980) at the Pt. Arena to Cape Mendocino region, 

warm oceanic water had moved closer to shore and the temperature gradients 

between the oceanic and upwelled waters were more intense. 

*Intrusions of warm waters into Monterey Bay are evident in both 1980 and 1981. 

Temperatures were higher in 1981; Ano Nuevo area values were up to seven degress 

higher in 1982. 

October: (Figures 8, 9, 10) 

* Between Cape Mendocino and Pt. Arena in 1980 waters were up to 5OC cooler 

than in 1981 and 1982. At the upwelling center off Cape Mendocino SST's were 10 

OC in 1980, 13OC in 1981 and 15OC in 1982. 

*The warm oceanic intrusion north and south of the upwelling plume off Cape 

Mendocino was about 4OC warmer in 1981 and 1982 than in 1980. Also, the 

onshore-to-offshore thermal gradient was stronger in the latter two years. 
9 

*In the southern half of the area surveyed, the inter-year pattern was less variable 

than in the north. Low SST's indicative of upwelling appeared in all years near Pt. 

Sur and a cool coastal patch was present between Point Conception and Point 

Buchon. The SST values varied only by one or two degrees between years in that 

area. 

SUMMARY 

It is evident that the coastal waters surveyed generally were warmer in 1981 and 

1982 than in 1980. Upwelling occurred in all three years but warmer SST's were 

observed in the later years. It is likely that the surface layer was deeper than 

usual in 1981 and 1982, so that cooler strata did not reach the surface. In-situ 

warming cannot be discounted as a likely factor, however. 

The series of charts offers to interested investigators the opportunity to compare 

sea surface thermal structure and features on a monthly interval as well as among 

the three years covered by the surveys.
