Assessment and establishment of a long term monitoring scheme on the burden of the marine environment and marine biota caused by marine debris

Project description

For implementing the Marine Strategy Framework Directive (MSFD) information on the current status and the establishment of feasable monitoring schemes are urgently needed. To achieve a good environmental status, the MSFD claims that marine debris should not cause any harm to the marine environment (Descriptor 10). This also includes small particles, such as microplastics (MPs). A trophic transfer MPs was already proven between mussels (Mytilus edulis) and crabs (Carcinus maenas). However, information on the occurence of microplastics in top predator species of German waters are lacking. Due to their position within the foodchain all three species [harbour porpoise (Phocoena phocoena), harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus)] are most likely accumulating uptaken particles. Carcasses stranded along the coastline of Schleswig-Holstein are transported to the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) of the University of Veterinary Medicine, Hannover.
