Benthic epifauna German Bight (North Sea) since 1999IngridKrönckeSenckenberg am MeerIngridKrönckeassociatedParty2013-04-22Samples were collected with a 2-m beam trawl during surveys with the RV "Walther Herwig III" from 1998 to 2011 (with exception of 2001 and 2002). All samples were taken in summer (July/August). The surveys were part of the
International Bottom Trawl Survey (IBTS) and covered 24 ICES rectangles (30 x 30 miles) from 53.5
to 56.0 degree N and 3.0 to 8.0 degree E. The study area included the inner
German Bight with its shallow West and North Frisian coasts, the deeper Oyster Ground, and the shallow northeastern Dogger Bank.

Benthic epifauna sampled with a 2m beam trawl
Epifauna was sampled with a 2m beam trawl. The beam trawl was fitted with a net of 20 mm mesh and a codend of 4 mm mesh. A SCANMAR depth sonar was attached to its top to determine the exact time and position of contact with the seabed. From the moment of contact with the seabed, the beamwas towed at a speed of 1.5 to 2 knots for 5 min. Samples were sieved over a 5 and 2 mm mesh. For details see attached references
