The consortium met at Sorbonne University in Paris on the 25-26 October 2023. This event was also held virtually via Zoom. This meeting was organised in collaboration with the consortium for the H2020-funded project SO-CHIC allowing for overlap to encourage knowledge exchange, collaboration and networking. The meeting was in conjunction with the H2020 project SO-CHIC annual meeting (23-24 October 2023) and a jointly organised scientific conference on 24-25 October 2023. The event brought together several Southern Ocean and cryosphere scientists from OCEAN:ICE, SO-CHIC, but also from other projects funded by the European Union, the European Space Agency, UK Research and Innovation, and related projects from the EU Polar Cluster and beyond. The proceedings of the SO-CHIC and OCEAN:ICE Joint Project Conference are going to be made available in the OCEAN:ICE Zenodo community Ocean-Cryosphere Exchanges in Antarctica: Impacts on Climate and the Earth System in the upcoming weeks.
