Seafloor Litter - Material categories percentage per trawl per year

This visualization product shows marine litter material categories percentage per trawl per year.

EMODnet Chemistry included the gathering of marine litter in its 3rd phase. Since the beginning of 2018, data of seafloor litter collected by international fish-trawl surveys have been gathered and processed in the EMODnet Chemistry Marine Litter Database (MLDB). The harmonization of all the data has been the most challenging task considering the heterogeneity of the data sources, sampling protocols (OSPAR and MEDITS protocols) and reference lists used on a European scale. Moreover, within the same protocol, different gear types are deployed during fishing bottom trawl surveys.

Harmonization of the material categories between ICES and MEDITS lists has been performed and the following calculation has been applied : Material % = (∑number of items of each material category)/(∑number of item of all material categories)*100

More information is available in the document attached.
