HE003:
Freshwater Fluxes in the Arctic Ocean – North Atlantic Climate System


Session ID#: 23525

Session Description:
Oceanic and sea ice freshwater fluxes in the Arctic Ocean – North Atlantic climate system impact thermohaline and convective processes, with far-reaching influence on climate. Increased freshwater fluxes to the Arctic Ocean along with the wind-driven anticyclonic circulation have resulted in growing freshwater content in the Beaufort Gyre. There is no observational evidence of significant changes in freshwater fluxes between the Arctic Ocean and the North Atlantic. Yet freshwater flux from the Greenland Ice Sheet is clearly increasing and may be impacting thermohaline processes in the North Atlantic. It is a priority to discern the driving mechanisms, the role and consequences of changing freshwater fluxes into the Arctic Ocean and North Atlantic. This session solicits papers addressing issues related to oceanic freshwater fluxes (liquid and sea ice) in the Arctic Ocean – North Atlantic climate system. Possible topics include: Propagation mechanisms, pathways and time scales of fresh water anomalies; residence time of fresh water; impacts of changes to the cryosphere; the role of freshwater in the future Arctic climate; the sensitivity of thermohaline circulation to freshwater fluxes; the relationship between sea ice and freshwater content in the ocean; and, biological and environmental consequences of increased freshwater fluxes.
