Source Data: Dr. Ric Brodeur (NOAA; rick.brodeur@noaa.gov), derived from surface trawls conducted as part of the BPA Plume Survey. Additional calculations by C. Barcelo (OSU). Additional Calculations: Geometric mean catch per unit effort (CPUE, #/sq. km) from Newport, OR (44.6 deg N, 124.0 deg W) to Father and Son, WA (48.24 deg. N, 124.7 deg W) by year; Numbers of individuals were recorded for each species caught in each haul and were standardized by the horizontal distance sampled by the towed net as CPUE. Yearly abundance data were obtained by combining (summing) the standardized count data of each species captured during June for each year. All CPUE estimates were log transformed.
