Abstract:
Drymass (mg DM m-3) of zooplankton taxa was calculated using conversion factors from biovolume to dry mass as described in Cornils et al. (2022) from samples of Polarstern cruise PS106 (SIPKA). Samples were taken with the RMT1 net with a mesh size of 320 µm. . Prior to the analysis each sample was fractionated into the following size classes: 0 – 0.5 mm, 0.5 – 1 mm, 1 – 2 mm, 2 – 4 mm and >4 mm). Samples were analysed via image-based ZooScan analysis. The classified images are available at the web application EcoTaxa: https://ecotaxa.obs-vlfr.fr/prj/2534.
