Cooperative Biogeochemical & Physical Model Framework for the Northwest Atlantic and Canadian Arctic Gateway

This research will develop a multi-scale computer model framework of the Northwest Atlantic Ocean and Canadian Arctic Gateway, providing a basic foundation from which to construct the physical, biological, geological and chemical aspects of the ocean. This model will improve prediction of marine conditions and lead to a better understanding of the effects of climate change on the region.

About the research

The set of models produced by this research project will involve the physical, chemical, biological and geological processes that determine the state of the ocean and the marine life it supports. It will consist of:

  • Ocean circulation (currents, tides and other large movements of water involved in ocean physics)
  • Ocean waves (which move water and the life and nutrients it holds and transfer chemicals such as carbon dioxide and nitrogen between the ocean and atmosphere)
  • Sea ice (including freeze-up and thaw and changes in extent)
  • Biogeochemistry (which examines the role of oceanic biology, geology and chemistry).

The impact

This research is important because it will contribute to biogeochemical and physical model framework that supports accurate predictions of the Northwest Atlantic marine environment. In particular, the framework will help predict future marine environmental conditions, forecast extreme maritime events (supporting safe shipping) and predict the effects of climate change on shifting ecosystems and variable fish stocks. 

The research team:

The team of researchers comes from Dalhousie University and Memorial University of Newfoundland, co-led by Katja Fennel of Dalhousie University, who holds the Canada Research Chair in Marine Prediction and Jinyu Sheng, a Professor of Oceanography at Dalhousie University. In June 2018, Dr. Sheng was honoured with the Francois J. Saucier Prize in Applied Oceanography by the Canadian Meteorological and Oceanographic Society in recognition of his work to develop numerical ocean models for the improved understanding of coastal, shelf and ocean dynamics and extreme marine events off Canada’s east coast. 

Team members include Youyu Lu, Will Perrie, Entcho Demirov and Eric Oliver.
