Science / project summary

The PIs have successfully developed a high-resolution unstructured-grid, finite volume coupled ice-ocean model for the Arctic Ocean (AO-FVCOM). AO-FVCOM has been validated via comparison to observed data under climatological conditions. Now they seek support to work on the following three tasks: 1) Calibrate and validate AO-FVCOM using observational data collected in the Canada Arctic Basin and its marginal Chukchi and Beaufort Sea. This region is chosen for intense study because it has the most pronounced loss of sea ice extent and thickness in recent years and its unprecedented coverage by multiyear national and international field and modeling studies. 2) Apply the new calibrated and validated AV-FVCOM to investigate the following scientific topics: a) improve understanding of the circulation of the Alaskan Coastal Current and Pacific and Atlantic waters in the study region, b) revisit scientific questions and methodological problems associated with shelf-basin exchange (SBE) processes in the region, and c) apply AO-FVCOM to investigate transformations and transports of fresh water (both liquid and solid) from freshwater sources (Bering Strait, rivers, central Beaufort Gyre, precipitation) towards the North Atlantic Ocean via Fram and Canadian Archipelago Straits. 3) Train a Ph.D. student in advanced Arctic Ocean modeling. Successful completion of this project will provide an additional protocol for modeling Arctic Ocean processes. It will also advance understanding of the circulation and mixing processes in the Arctic Ocean, processes which will grow in socio-economic importance with increasing ice loss and development activities in this part of the globe.
