The Gulfwatch contaminants monitoring program in the Gulf of Maine: Are its data being used for ocean protection, with special reference to Nova Scotia, Canada?

The Gulfwatch Contaminants Monitoring Program is part of the Canada-US, Gulf of Maine Council on the Marine Environment (GOMC). Programs monitoring legacy toxic substances, i.e., chemical contaminants, such as Gulfwatch, collect and analyse environmental samples (e.g., blue mussels), interpret the data, and report on chemical levels and trends (spatial and temporal) in coastal waters. This study explored the extent to which its extensive information (data, reports, papers) has been used broadly and by Nova Scotia, a GOMC member. A mixed-methods study was conducted, using quantitative and qualitative metrics. Citations to some Gulfwatch papers and analysis of use of the Gulfwatch website showed that its data and information were accessed, mostly by government departments. However, interviews revealed that the departments were not using the data to inform Nova Scotia provincial coastal policy or practices. Recommendations are presented to improve the visibility and use of information provided by long-term, environmental monitoring programs.
