The GLSC is using advanced technologies to carry out multi-partner hydroacoustic fishery surveys and experiments during August and September, 2022, in western Lake Superior. The work is being conducted to learn how existing hydroacoustic methods can be improved to provide more accurate and precise estimates of fish populations in western Lake Superior and the Great Lakes more generally. Six different research vessels operated by the USGS, the states of Minnesota and Wisconsin, the Grand Portage and Red Cliff Bands of Lake Superior Chippewa, and the Province of Ontario will be used along with four autonomous vehicles during the month-long fisheries science mission.
