HE51A:
Moving Beyond Melt: The Impact of Melting Glaciers, Icebergs, and Sea Ice on Ocean Environments I

Session ID#: 92369

Session Description:
Rapid changes in sea-ice cover and ice sheets, occurring at both poles, have sparked increasing interest in determining their climatic drivers and their global implications, such as reduced albedo or sea level rise. The local and regional impacts of melting ice on the ocean, on the other hand, have received comparatively less attention. The polar oceans are primarily stratified in salinity and freshwater forcing has direct impact on water mass transformation. Beyond the direct effect of a predicted increase in freshwater input from the polar cryosphere, there is growing evidence that variations in ice melt can also have significant impact on ocean biogeochemistry, marine ecosystems, sedimentation and sediment transport, air-sea exchange and regional ocean circulation. Here we solicit observational, modeling, and theoretical studies that address the impact of melting glaciers, ice sheets, sea-ice and icebergs on the physical, chemical and biological ocean, on marine ecosystems and on the regional economies that depend on marine ecosystem services.
