Great Lakes Observing System (GLOS)
Taking the Pulse of the Great Lakes

The Great lakes Observing System (GLOS), provides public access to critical real-time and historical information about the Great Lakes, St. Lawrence River and interconnecting waterways for use in managing, safeguarding and understanding these valuable bi-national resources. Observing systems (e.g., sensors and buoys) are the primary means for gathering information — taking the pulse of the Great Lakes — on the chemical, biological and physical characteristics of the Great Lakes ecosystem.

GLOS is one of 11 regional associations that form the U.S. Integrated Ocean Observing System. Resource managers, researchers, educators, commercial shippers, recreational boaters, beach users and homeland security interests all use GLOS data and information.

Michigan Sea Grant is working with the Great Lakes Sea Grant Network to facilitate greater understanding about and use of observing systems data in Michigan. Activities include:

  • CoastWatch, a surface water temperature data website, developed and maintained by Michigan Sea Grant and the Michigan State University Remote Sensing and GIS Research and Outreach Services.
  • Grand Traverse Bay Coastal Observing System, a nearshore, real-time environmental monitoring buoy. Michigan Sea Grant assists in the annual deployment of this buoy, developed and operated by the University of Michigan Marine Hydrodynamics Laboratory.
  • GLOS curriculum development, in collaboration with COSEE-Great Lakes. Michigan Sea Grant is developing lessons and activities that focus on surface water temperature data from CoastWatch.
