Search effort (in linear kilometers) and number of groups 
seen for each species on each of the surveys conducted 
by the NOAA Southwest Fisheries Science Center (SWF- 
SC) and the California Cooperative Oceanic Fisheries 
Investigations (CalCOFI) and included in the analyses 
for this study. El Nino cruises were combined into sea- 
sons for analyses. Seasons are defined as follows: spring 
was February-April, summer was May-July, fall was 
August-October, and winter was November-January. 
Species abbreviations are as follows: Dsp -Delphinus 
Yen, P. P. W., W. J. Sydeman, S. J. Bograd, and K. D. Hyrenbach.
