"This report provides an overview of the survey objectives and includes a summary of the survey equipment, acoustic-system calibration, sampling and analysis methods, and preliminary results.

Final biomass and abundance estimates for other CPS and krill will be reported separately"-- Introduction. [doi:10.7289/V5/TM-SWFSC-580(http://doi.org/10.7289/V5/TM-SWFSC-580)] Kevin L.
