Short summary
In this study, 2-year mooring observations show the evolution of temperature, salinity, and currents in the northern Barents Sea. Inflow of Atlantic Water from the north in autumn and winter was the main driver of the seasonal cycle in the ocean. Winds modulated the inflow on shorter timescales. The upper-ocean state reflected how much sea ice had previously melted in the area. The import of ocean water and sea ice from adjacent regions plays a key role in the complex air–ice–ocean interplay.
