Hydroacoustic data from uncrewed surface vehicle (USV) overtakes in Lake Superior, 2022
These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels in Lake Superior in 2022. The powered vessels overtook the USVs to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into four depth groups for analysis. Each USV transect was binned into 30-sec intervals and measured hydroacoustic values were averaged in this region. To compare vessels and USVs, parallel overtakes (overtakes where vessel and drone followed the same path) which were ~2 km long, were measured by both platforms and the differences between acoustic measures compared.
