Collection of the material has been done with beamtrawl by the Norwegian Institute of Marine Research (IMR) on the MAREANO surveys. The material is then fixed in formalin/ethanol and processed in laboratories on land. Results are entered in the database marbunn. Stated measurement values ​​are calculated based on the size of beamtrawl and any subsampling on board and on land.

The data set shows points with analyzed physical samples from beamtrawls. The data set shows species diversity (by the number of different species), individuals (aggregated sum of the number of individuals) and biomass (aggregated value of individual weight).
Beamtrawl is a small bottom trawl that is equipped with a relatively coarse (often 2-5 mm) net. This collects the larger organisms that live up on the bottom and a little down in the top layer of the sediments. In the MAREANO context, the beamtrawl is usually towed along the bottom for 5 minutes.
