In November, an Arctic Data Portal was launched to improve the availability, quality, timeliness, and accessibility of essential marine in situ data from the Arctic region. The Portal is a joint initiative of EMODnet, CMEMS, INSTAC, Copernicus In Situ Coordination Group and EuroGOOS, and was implemented under EMODnet Physics. The project started with two events: a kick-off meeting (20 November) bringing together representatives from Copernicus, EMODnet, European Polar Board, the Southern Ocean Observing System, the Arctic Data Committee, and EuroGOOS, and a dedicated webinar (27 November) attracting over 100 attendees in 24 countries to discuss the role of the Portal for unlocking new data that will improve the marine services in the Arctic.
