The Arctic ROOS and the Arctic Regional Team of the OceanPrediction DCC organised a joint online workshop on 17 and 18 January, titled ‘Ocean and sea ice forecasting in the Arctic’. The workshop featured keynote presentations by Laurent Bertino (NERSC) on advances in modelling salinity in the Ice-covered Arctic, and Maria Berdahl (European Commission DG DEFIS) on the development of Copernicus’ polar applications. 

The workshop explored the current state of the art in ocean and sea ice forecasting services in the Arctic, including numerical modelling and observations needed to support forecasting. Downstream user services and applications were discussed, along with perspectives for future priorities. Discussions between presenters and participants identified recommendations for developments to existing forecasting, which will contribute to the ongoing work of Arctic ROOS and the Arctic Regional Team of the OceanPrediction DCC.
