This project will further refine and validate a climate modelling tool to provide geographically detailed projections of future changes in biogeochemical conditions for the Gulf of St. Lawrence, Scotian Shelf and the Gulf of Main. The tool will inform the implementation of a Marine Protected Areas Network in the Gulf of St. Lawrence and many other resource- and ecosystem-related decisions. It can also be used to evaluate:

  • habitat changes and, therefore, future changes in the distribution of commercial species;
  • changes in habitat quality for certain species and the resulting impact on their condition (e.g., acidification of waters inhabited by lobster, shrimps and snow crabs); and
  • changes in ecosystem carrying capacity in relation to primary production.

Mapping these changes will provide information for a study of the impact of climate change on lobster in the southern Gulf of St. Lawrence, and can also be used to inform siting decisions for marine protected areas on the Scotian Shelf.
