A system of ocean and sea-ice forecasting models, based on Nucleus of European Modelling of the Ocean (NEMO), are being developed under major initiatives of Canadian government and universities. Hindcasts of ocean hydrography, circulation and sea-ice in the North Atlantic, Arctic and North Pacific Oceans are produced at high-spatial resolutions. These model results are evaluated with a variety of in situ and satellite ocean observations. The analysis improves understanding of ocean circulation dynamics and reveals challenges in simulating the meso-scale eddy variability.

Integrated Laboratory and Modelling Study of the Fate of Spilled Oil in Ocean

Increasing oil and gas activities lead to increased risk of marine oil spill. The recent example of Deepwater Horizon oil spill has shown that the oil spill is difficult to response and reliable oil spill models are needed to predict the movement, fate and environmental effects of the spilled oil. However, major research gaps exist in oil-mineral-aggregates formation, subsurface blowouts, oil-ice interaction, etc. Due to the lack of data collected at fields, we carry out meso-scale experiments with a 30 m wave tank and obtain various parameters of hydrodynamics and chemical processes. Mathematical descriptions of these processes are developed based on analysis of laboratory data, and are then integrated into existing three-dimensional oil spill models to improve our ability to better predict the fate/transport processes spilled oil in the marine environment.
