Benthic epifauna North Sea (6 "Boxes") since 1998IngridKrönckeSenckenberg am MeerIngridKrönckeassociatedParty2013-01-17Samples were collected with a 2-m beam trawl during surveys with the RV "Walther Herwig III" since 1998.
All samples were taken in summer (July/August). Box A was addtionally sampled in winter (January). The surveys were part of
the German Small-scale Bottom Trawl Survey (GSBTS). Abundance and biomass of all epibenthic species were recorded. 2m beam trawbenthic epifaunatime seriesObtain permission from data set owner(s)Box A: 54 degree 17 min to 54 degree 27 min N, 06 degree 58 min to 07 degree 15 min E;

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 beam was towed at a speed of 1.5 to knots for 5 min. Samples were sieved over a 5 and 2 mm mesh. For details see attached references
