This is a child item of the USGS Data Release: https://doi.org/10.5066/F7TQ60GV These data comprise of hydroacoustic backscatter data along transects in the North Pacific and Bering Sea conducted in August 2012 and 2014. We echointegrated hydroactoustic backscatter and used that as a proxy for forage fish biomass. The dataset consists of comma delimited files for 120Hz frequency. Each file contains analysis exports from EchoView Software Pty Ltd. ver. 5.4.
