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.
