EK60 Water Column Sonar Data Collected During DS0806

2008 Summer CCE. The California Current Ecosystem Survey (CCES) was a two ship synoptic survey of the western U.S. coast of North America. The first survey (using the NOAA Ships David Starr Jordan, DSJ, and Miller Freeman, MF) was conducted in spring (MF working north to south from April 1 – May 3 and DSJ working south to north from March 24 – May 1, 2008). The second survey using only the David Starr Jordan extended the survey into the summer season (DSJ working north to south from July 6 – August 20, 2008), repeating most of the transect lines of the April survey, and applying the same methodologies. Although the primary objective was to collect data required for the biomass estimate of Pacific sardine (Sardinops sagax), additional data were collected to describe the pelagic ecosystem across a range of trophic levels.
