With GLRI funding, NOAA has developed a satellite water clarity-turbidity index (CTI) as a simplified way to capture major changes in water clarity/turbidity across all water types in the Great Lakes. The CTI is a convenient and holistic assessment tool for water quality management.
Millions of people rely on the Great Lakes for recreation, industry, and drinking water. Climate change is affecting precipitation events and temperatures throughout the Basin and future predictions suggest this will continue. This informative story map includes history of the region, and historical water level trends and impacts.
Shay Keretz, a CIGLR graduate research fellow, is working with her advisors to comprehensively survey the large, deep, and fast-flowing parts of the St. Clair-Detroit River System for both unionid and dreissenid mussels. This work will contribute toward native mussel conservation and management.
The NOAA Great Lakes Environmental Research Laboratory (GLERL) is one of seven Federal research laboratories in the Oceanic and Atmospheric Research line office of NOAA. Designated on April 25, 1974, GLERL was established to provide a focus for NOAA’s environmental and ecosystem research in the Great Lakes and coastal marine environments.
NOAA GLERL's Lake Michigan Field Station (is the home port for NOAA Great Lakes vessels, which operate throughout the Great Lakes. It is also the platform for the long-term observations research program on Lake Michigan.
