Mechanisms of Offshore Solid and Liquid Freshwater Flux from the East Greenland Current

Explore the mechanisms controlling freshwater export from the East Greenland Current in this 45-minute conference talk presented at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the use of idealized numerical models and scaling theory to investigate both liquid and solid freshwater fluxes. Examine how a regional, coupled ocean/sea ice model is applied to various calculations, with key parameters being varied and scaling theory used to interpret the results. Learn about the primary drivers of offshore ice flux in late winter, including internal stresses, sea ice thickness on the shelf exiting Fram Strait, and meridional wind strength over the shelf. Discover the seasonal variations in liquid freshwater flux, with offshore eddy fluxes dominating in late summer and onshore fluxes occurring in winter due to ice-ocean stress. Gain insights into the key nondimensional parameters identified by the scaling theory and how they align with the numerical model's parameter dependence.
