The Southern Ocean plays a critical role in controlling the exchange of heat, carbon and nutrients between the atmosphere, surface and deep oceans. Since this region is highly under-sampled for the purpose of assessing the environmental variability, understanding how the Southern Ocean responds to external forcing is critical to our understanding of the climate change. We invite presentations from observational and modeling studies to enhance our understanding of the physical, chemical, and biological processes of the Southern Ocean, linkages between these processes, ocean-ice interactions, and response of these processes and interactions to the changes in climate.

The Arctic Ocean is experiencing rapid environmental changes due to rising air and water temperatures, and loss of sea ice. The rapid environmental changes in the Arctic Ocean have resulted in ocean circulation changes, freshwater budget changing, the ecosystem and biochemical cycles as well as extreme weather events. How is the Arctic Ocean environment expected to change in the future under the influence of climate change? What are the consequences of these changes for biogeochemical cycles in the Arctic and beyond? How will the ecosystem respond to these changes? This session seeks to understand major changes occurring in the Arctic Ocean and the mechanisms responsible for these changes.

The Circum-Antarctic Ridges (CAR) occupy about one-third the length of the global ocean ridge system, and yet they remain as the least surveyed area because of rough Antarctic sea conditions. Since 2011, KOPRI went on 4 expeditions and brought back excellent science results about tectonics, geochemistry and biology. This session provides a forum to discuss the scientific results obtained from past cruises and the international collaborations for the future cruises on this remote mid-ocean-ridge system.

The warming of the Arctic is causing rapid changes in the Arctic active geological processes at the seabed. One concern is the potential release of methane from decomposing subsea permafrost and the associated permafrost gas hydrates. While our knowledge of the amount and mobility of methane in this environment is limited, there is a potential that it could represent a ‘time bomb’ that may influence future global warming. This session aims to introduce the latest international research results on the rapid changes of the Arctic sub-seabed and to assert future research priorities that can be pursued through international collaboration.

The Antarctic ice sheets and sea ice have repeatedly retreated and advanced on orbital-scale during the late Quaternary. The variations in cryosphere influenced surface water conditions in the Antarctic Ocean, including changes in light intensity/open ocean duration, primary production, and water mass circulation. Deposition on the Antarctic Ocean is determined by surface environmental changes in association with changes in ocean-cryosphere interaction. Thus, the sediment core records from the Antarctic continental slope and rise would provide glacial-interglacial records on dynamics of paleo-ice sheets and sea ice and their relevant surface water condition changes. In addition, Antarctic continental shelf records would provide information on how oceanic condition changed in response to the retreat of ice sheets/shelves since the last glacial period. Researches on paleoeanographic changes and paleo-ice sheet changes using various proxies in the Antarctic continental margin are welcome in this session.

The Arctic Ocean has been subject to rapid and dramatic environmental changes on both historical and geological time scales that, in turn, modulate the Earth’s climate forcing such as surface albedo, global overturning circulation, and carbon cycle. All contributions on paleoceanographic and paleoclimatic variability in the Arctic Ocean are welcome to this session, particularly those integrating paleo-records with modern processes and observation. We aim to advance our knowledge and understating of the Arctic Ocean and its role in the global climate system.
