Session ID#: 29774
Rapid changes at both poles have increased the importance of physical and chemical interactions that occur between the ocean and ice shelves, glaciers and icebergs. Exchanges of heat and freshwater exert feedbacks on terrestrial ice loss, and marine ice concentration. Glacial meltwater can alter ocean stratification, circulation, and biological productivity. The chemical load transported via subglacial and englacial waters can be a major vector for the supply of iron and other limiting nutrients to the marine ecosystem. Temperature and sea level rise increase the erosion of coastal and shallow subsea permafrost leading to oceanic delivery of terrestrial organic compounds and other permafrost-trapped chemical species. The effects of these melt processes on ecosystem biomass and community structure/activity are poorly known, as is the spatial extent of these impacts. We also know very little about how seasonal, episodic and anticipated future losses will manifest in ocean circulation and coastal ecosystems.
Building on recent contributions to our understanding of relevant processes, this session seeks to bring together multi-disciplinary researchers engaged in observing and modeling these ice-ocean interactions in polar regions, including those around Greenland and Antarctica, and their impact on ocean physics, chemistry and biology.
