This visualization product displays beaches locations where a monitoring protocol to collate data on Macrolitter has been applied. Reference lists associated to those protocols have been indicated with different colors. EMODnet Chemistry included the gathering of marine litter in its 3rd phase. Since the beginning of 2018, data of beach litter 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 and reference lists used on a European scale. Preliminary processing were necessary to harmonize all the data : - Exclusion of OSPAR 1000 protocol, - Separation of monitoring surveys from research & cleaning operations - Exclusion of beaches with no coordinates - Normalization of survey lengths and survey numbers per year - Some categories & some litter types have been removed Data collected using "OSPAR 1000" protocol have been removed for all the products for now, following the approach of OSPAR that it is not including these data anymore in the monitoring. More information is available in the document attached.
