Planned Bathymetric Mapping in 2021


This year the MAREANO programme will continue the bathymetric mapping in the Barents Sea, although only smaller transects. Therefore, there will not be a tender competition for the procurement of bathymetric data acquisition and processing.

The MAREANO survey continues to the Sklinna Bank off mid-Norway


Cruise diary: The ongoing MAREANO survey has now moved southwards from the Træna Bank to the Sklinna Bank on the mid-Norwegian shelf. The seafloor terrain here varies more than farther north, and we have found hitherto unregistered cold-water coral reefs.
