The Marine Environment Database (MUDAB) records physical, hydrographic, hydrochemical and biological parameters of the marine environment for the German part of the Baltic Sea and the North Sea. The central database supports the activities of the Bund/Länder-Arbeitsgemeinschaft Nord- und Ostsee (BLANO). In addition, MUDAB makes a significant contribution to Germany's international commitments to provide environmental data for marine protection. Among other things the Marine Environment Database provides measurement data in support of the international "OSPAR Commission” and the "Helsinki Commission (HELCOM)”. Last but not least, MUDAB makes a significant contribution to the "Environmental Reporting Sea" (SOE Report) to the European Environment Agency in Copenhagen (EEA).
