Ocean-Cryosphere Exchanges in Antarctica: Impacts on Climate and the Earth System (OCEAN:ICE)

The NASC participates in three work packages:

• WP 10 “Subpolar circulation, heat delivery and water mass export” is the oceanographic component of the project. NASC will fill in some of the remaining “data gaps” around Antarctica by deploying an additional set of innovative equipment – profiling floats in the Southern ocean. These are autonomous oceanographic instrument platforms used for making subsurface measurements in the ocean without the need for a vessel, propeller, or a person operating it. Such floats measure the physical and chemical parameters of the ocean in detail, such as measuring the direction and water velocity or the temperature and salinity. These measures will help to understand better the seasonal exchanges between cold Weddell Sea waters and relatively warmer central West Antarctic Peninsula waters. Within this WP, 6 argo floats will be deployed at Bransfield Strait during the Antarctic season of 2024-2025.
  
• WP 11 ‘Atmosphere and Ocean Dynamics’. This package focuses on the implementation of dynamic modelling of the atmosphere and ocean based on historical estimates of precipitation (rain/snow) and the occurrence of extreme events. In addition, NASC researchers will examine the impact of precipitation on ice shelf mass budget by snowfall and rain using high resolution regional atmospheric modelling.
• WP 12 ‘Project management, data management, dissemination, communication, engagement’. This package is dedicated to communicating project results and integrating them into global science.

OCEAN ICE will provide:

• Practical experience how to use the innovative oceanographic equipment (argo floats) to study the dynamics of water masses in the Southern Ocean;
• Involvement of Ukrainian scientists in global modelling of sea circulation and atmospheric phenomena to better understand the impact of glacial melting on the Southern Ocean currents and the corresponding meteorological changes;
• Integration of Ukrainian oceanographic and meteorological data into a single worldwide system that will provide a new assessment of ice sheet melting and its impact on ocean circulation.
