Multibeam echosounder measurements above experimental dumps near the German Baltic coast

Within the framework of the DYNAS-project (Dynamics of natural and anthropogenic sedimentation) two experimental dumps with different sediment compositions were deposited near the German Baltic coast in June 2001. Basing on this test dumping, the Baltic Sea Research Institute Warnemuende intended to investigate the physical and biological processes of an ocean dumping event on seabed and water body. From June 2001 to October 2004 the dumping site was surveyed by the GKSS Research Centre Geesthacht with a multibeam echosounder system. The survey data of the dumping site was used to investigate morphological changes of the seabed (Stockmann et al. 2009) and the survival rates of six different macrobenthos species depending on the burial depth (Powilleit et al. 2009).
