Climate Change and Thermal Sensitivity of Canadian Atlantic Commercial Marine Species
Our project identifies the vulnerability and sensitivity of commercially important marine species to climate change. To do this we identified the thermal limits for survival of these species throughout their lives and compared these to climate change predictions of oceanic temperature.
Shifts in temperature will not follow a linear, latitudinal gradient and of utmost importance to marine species are changes in circulation and stratification of coastal waters. At this stage, output of global climate models cannot be used to predict such changes. We believe our work will help to demonstrate the detail of information necessary for modelers to focus on regional models and improve resolution.
Much of the text on these web pages is derived from our final report to Canada's Climate Change Impacts and Adaptation Program. Material from those chapters is found in pages linked to "Results" above. Below is a brief description of what you will find in each page.
Sea surface temperatures
Chapter 2 - Sea surface temperature changes in the northwest North Atlantic under a 4°C global temperature rise (an analysis of present sea surface temperatures from satellite imagery and projected sea surface temperatures using the output of Atmosphere-Ocean General Circulation Models)
Chapter 3 - Species accounts (individual species accounts presenting general biology, commercial importance, thermal criteria, most vulnerable characteristic or life stage in terms of thermal parameters , and maps of present and predicted distributions)
Chapter 4 - Sensitivity analysis (an analysis and ranking of species with respect to their vulnerability to temperature change)
White papers produced for the World Wildlife Fund's "2 Degrees is Too Much!" program, their program brochure highlighting changes in Canada's natural resources, and a poster describing our methodology but examining a species important in New England waters.
