Summary

Abstract

An archive of multi-frequency and multi-beam echosounder data (Simrad .raw format), collected as part of SWFSC-FRD surveys of the U.S. west coast between San Diego, CA and Vancouver Island, BC. The archive contains echo power and inerferometric-phase-angle data that describe acoustic backscatter from marine organisms ranging in size from zooplankton to fish.
