Zooplankton and environmental parameters sampled under-ice during POLARSTERN cruise PS81 (ANT-XXIX/7)

Sampling was performed during RV Polarstern expedition PS81 (ANT XXIX/7), between 31 August and 2 October 2013, across the ice-covered Weddell Sea, between 61°S, 42°W and 58°S, 25°W. Horizontal hauls were performed with a Surface and Under Ice Trawl (SUIT). Environmental data were collected with sensors mounted in the SUIT frame. The SUIT consists of a steel frame with a 2 m x 2 m opening and two parallel 15-m long nets attached: PLK (0.3 mm mesh; 0.5 m of opening width) and SUIT (7 mm mesh, 1.5 m of opening width). Zooplankton data contains mezo- and macrozooplankton species with numbers of specimens at each event (station). Trawled distances to derive areal abundance can be found in the environmental data table
