Offshore wind is under development across Europe. In Norway, two areas (Utsira Nord, which is part of Vestavind F, and Sørlige Nordsjø II) have been opened with the goal of contributing to the national ambitions of 30 GW of installed power in 2040. This project aims at understating the area use of different marine species before, during, and after construction of the turbines in these two areas. We will use acoustic telemetry to track the presence, migration, and distribution of different fish species in the areas.
