Frequent sampling of microplastic particles in surface waters in the open parts of the Kattegat and Great Belt, Denmark

The EU Marine Strategy Framework Directive require that EU Member States establish appropriate strategies and sampling programmes for microplastic in the marine environment. We report the results of a second study sampling microplastics in the Inner Danish Water using the Ferrybox system onboard the ‘M/S Color Line Fantasy’ ferry between Oslo and Kiel. This study aimed to supplement and extend a pilot project following recommendations to increase sample frequency and sample volume.
