The main objective of the joint Nansen Legacy and A-TWAIN/SIOS-InfraNor mooring service cruise was the recovery and deployment of the projects’ moorings in the Barents Sea and north of Svalbard. Additionally, CTD stations with water sampling for both projects, a Seaglider deployment for NL, and mooring recoveries and deployments for partner projects were planned, depending on sea ice conditions and time available.
