Lake Superior Research Institute
Browse by
The Lake Superior Research Institute (LSRI) was created in 1967 and formally recognized by the University of Wisconsin’s Board of Regents in 1969. LSRI’s mission is to conduct environmental research and provide services that directly benefit the people, industries, and natural resources of the Upper Midwest, the Great Lakes Region, and beyond; provide non-traditional learning and applied research opportunities for undergraduate students; and foster environmental education and outreach in the Twin Ports and surrounding communities.
