The first pan European Marine Litter Database (MLDB) has been developed by EMODnet Chemistry, following the advice of MSFD Technical Group on Marine Litter. The database contains data of beach and sea floor litter from a variety of sources, including existing International and Regional Sea Conventions, and data submitted by EU Member States, EMODnet partners and external research or monitoring projects. A majority of datasets has come from existing monitoring projects which have published their data in project specific databases (i.e., OSPAR, ICES DATRAS). These databases may hold more and differently formatted information than is provided here, so direct comparison with these sources is not always possible.
