Results from Underwater Vision Profiler 5hd measurements from campaign ARCTIC2018 (Transdrift XXIV). Depth profiles for optical particle quantification (>~0.1 mm) and particle image acquisition (>~0.8 mm) were performed in August and September 2018 in the Laptev and East Sibirian Sea as well as the Nansen and Amundsen Basin onboard RV Akademik Tryoshnikov.This dataset provides the results of the particle image validation. Zooplankton and detritus images were validated with software assistance in Ecotaxa (Picheral, M., Colin, S. & Irisson, J.-O. (2017): EcoTaxa, a tool for the taxonomic classification of images. http://ecotaxa.obs-vlfr.fr.). Depth binned concentrations (individuals per m³) as well as volumes (volume per L) and the average equivalent spherical diameter (ESD) are shown for every identified group and taxon. Note that detritus sub-classes were used for training set creation only. Robust counts of total detritus as well as detritus sub-classes are provided in the detritus clustering file.
