Improving understanding of processes in the high-latitude and sea-ice covered oceans: Ongoing and future observation and modelling efforts

Session ID#: 259451

Session Description:
The polar oceans are subject to accelerating change, notably through rapid loss of sea ice, intense warming, changing ocean circulation, and an intensifying hydrological cycle. These changes affect many climatically-relevant processes, including atmosphere-ocean heat/CO2 fluxes, upper-ocean mixing, water mass formation (including dense water production), sea level rise and upper-ocean biological productivity. Nevertheless, observing and modelling the polar oceans remains difficult, particularly in the sea ice-covered and marginal ice zones, where strong spatial heterogeneity and lateral property gradients are found. This limits the evaluation and improvement of predictive models.

This session invites contributions from the in-situ observation, remote sensing and modelling communities of both the Antarctic and Arctic. Studies detailing novel methodology including underwater robotics and new satellite/airborne technologies are especially welcomed. Of particular interest are also studies that highlight the use of polar observing systems and those which identify observational gaps and assess ways to fill these gaps. Contributions related but not limited to MOSAiC, Antarctica InSync, the International Polar Year, and Polar Argo are encouraged. We also particularly welcome contributions from the sea ice community, and from diverse scientific fields such as physics, biogeochemistry, sea ice and climate predictability, and biology.
