Great Lakes science vessels work on a freshwater sea of more than 94,000 square miles (243,459 square km) helping scientists, educators and resource managers understand, restore and protect a global treasure.

GLASS is dedicated to improving communication & collaboration between science vessels & helping to best match the capabilities of all vessels with the needs of research & educational programs throughout the Great Lakes. This database includes U.S. & Canadian vessels in a wide range of sizes & capabilities. Information about active public & private research or educational vessels is posted. Information about old science vessels that are retired or no longer in service as science ships is also provided for reference and is marked: (historical). Use the ship locator map to find science vessels, check their status, locations, schedules & points of contact. Registered users can update information about vessels they operate, post news, job openings, announcements, shipyards & suppliers and other documents.
