Abstract:
Makrozoobenthos of soft-bottom benthic communiy was collected by van-Veen grabs and beam trawls to sample the infauna and epifauna. Further, the data contains a few hauls with otter trawls to sample the demersal fish fauna. Sediment data are included to specify the soft-bottom habitat. Samples were collected in autumn 2006 and spring 2007. Benthic data were collected in the North Sea, German Bight in the area of the Sylt outer reef. Based on sediment maps and multibeam echo sounder images, 15 stations of different sediments were defined. The sediment distribution in the study area is very heterogeneous even at small scales, with fine sand sections alternating with coarse sand or gravel as well as individual large stones. This mosaic of different habitats causes different bottom fauna communities. Data for the two sampling campaigns comprise different stations in these differing sediment mosaic. Biodiversity data of species include abundance (count data) and biomass (wet mass, g) per sample.
