Great Lakes Observing System


The Great Lakes Observing System (GLOS) is a nonprofit association dedicated to connecting data users with data providers in ways that are supportive of policy and decision making.

We envision a fully integrated, bi-national observing system that provides products and services to decision-makers, resource managers and other data users with input from members and partners, to foster understanding and inform decision-making related to the Great Lakes and St. Lawrence River System.
