Abundance of megafauna collected by Agassiz trawl during POLARSTERN cruise PS80 (ARK-XXVII/3, IceArc)

During the cruise ARK-XXVII/3 sampling of the megafauna was conducted by the Agassiz trawl (AGT) at seven stations. Agassiz trawls were taken along transects after the photographic survey by OFOS when the ice conditions were appropriate to obtain specimens to verify taxonomic identifications based on images. Trawl samples were washed through a sieve with 1 mm mesh size, sorted and preserved in 4% buffered formaldehyde. Some specimens with calcareous skeleton were preserved in 80% ethanol for taxonomic identifications.
