Gulf of Maine Gulfwatch Program

Gulfwatch is a chemical-contaminants monitoring program organized and administered by the Gulf of Maine Council on the Marine Environment. Since 1993, Gulfwatch has measured contaminants in blue mussels (Mytilus edulis) to assess the types and concentration of contaminants in coastal waters of the Gulf of Maine. It is one of the few monitoring programs and the only one in the Gulf of Maine to be coordinated across international borders.

Gulfwatch is coordinated and conducted by scientists and managers from agencies and universities around the Gulf. The program operates under the guidance of the Gulf of Maine Council's Contaminants Monitoring Committee ( formerly Environmental Quality Monitoring Committee) and is supported with funding from the Gulf of Maine Council on the Marine Environment and the U.S. Environmental Protection Agency.
