The AGU Ocean Sciences Meeting will take place in February 2020.  Abstracts are invited for Southern Ocean and Antarctic-related sessions:

OB007 - Complexity, Connectivity and Change in Southern Ocean Food Webs

Changes in ice, ocean and ecosystem dynamics in the Southern Ocean are affecting biodiversity at all trophic levels, from plankton to whales. Food-web processes are fundamental in maintaining the structure, functioning and resilience of ecosystems and hence in ecological responses to change. This session is intended to bring together studies on emerging areas of research including the spatial and temporal variability and connectivity of food webs, food web resilience properties and biodiversity, interactions between pelagic, sea-ice or benthic food webs, importance of food-web processes in biogeochemical cycles (including carbon budgets) and combined effects of past and current harvesting and climate-related changes on individual species and their food web interactions.

HE004 - Effects of Ice Loss on Marine Biogeochemistry and Biodiversity

The Arctic and Antarctic oceans are undergoing drastic changes in the extent of their sea-ice and ice-shelves. This has effects on biodiversity, structure and function of polar communities and will change these ecosystems, including major implications on the biogeochemical cycles. This session invites contributions that provide up-to-date information on species richness and biogeographic responses in marine biodiversity adapted to ice-covered environments as well as on their phylogeographic relationships and how they affect biogeochemical cycles.

- Ice-Ocean Interactions and Circulation around the Antarctic Margins

Processes occurring at or close to the ice-ocean interface around Antarctica influence the state and circulation of a large proportion of the global ocean. This session will showcase recent advances in understanding the physical processes occurring in the Antarctic marginal seas, across the Antarctic continental shelf and slope, and within the ocean cavities beneath floating ice shelves.

HE007 - Moving beyond melt: the impact of melting glaciers, icebergs and sea-ice on ocean environments.

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. There is also 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.

Abstract submission is open on the conference website until 11 September 2019.
