Phase 4 (2015-2018)

Integrated Marine Geoscience to Guide Environmental Impact Assessment and Sustainable Development in Frobisher Bay, Nunavut

Project Leader(s)

Edinger, Evan

This project will create geological and biological seabed maps for Frobisher Bay, Nunavut, showing the distribution of bottom types and marine geohazards, as well as the distribution of marine biodiversity. By the end of this project, most of Frobisher Bay will have been mapped using multibeam sonar. Biological sampling and mapping of seabed habitat maps will describe marine biodiversity and identify sensitive habitats that might require protection during projects related to infrastructure, resource and fisheries development. Biological studies will include re-sampling sites previous studied in the 1970s and 1980s to assess long-term variation in species composition, and to map the extent of the habitat types represented by these long-term study sites. Geological seabed maps will identify marine geohazards including sites of underwater landslides, and areas prone to such slope failures, or tsunamis. The project will also determine the history of past underwater slope failures, to help guide estimates of how frequently such events occur, and to help determine how severe a threat marine geohazards might pose to marine and coastal resource development in Frobisher Bay.
