Monitoring of Seafloor Litter on the Dutch Continental Shelf : International Bottom Trawl Survey 2021, Dutch Beam Trawl Survey 2020

This report presents the seafloor litter composition, abundance and spatial distribution based upon catches of the regular fish surveys, the International Bottom Trawl Survey (IBTS) and the Dutch Beam Trawl Survey (BTS). Only the catches on the Dutch Continental Shelf (DCS) are used. To assess the status of seafloor litter on the DCS, the Dutch data are supplemented with those from international partners surveying the DCS within the IBTS.
