    List of taxa in the OFOS photographic survey images and in Agassiz trawl samples during POLARSTERN cruise PS80 (ARK-XXVII/3, IceArc) (2018)

    Description: A photographic survey was carried out during the expedition ARK-XXVII/3 to the Nansen and Amundsen basins. The seafloor was photographed using a towed Ocean Floor Observation System (OFOS). Nine transects were performed: four in the Nansen Basin between 83-84°N and 18-110°E at depths 3571-4066 m, and five in the Amundsen Basin between 83-89°N and 56-131°E at depths 4041-4384 m. All images were analysed and stored using the image analysis program and database BIIGLE (BIIGLE.de). Visible megafauna was identified to the lowest possible taxonomic level. Taxonomic identifications were made with the assistance of zoological experts. The following taxa/organisms were excluded from statistical analyses: infauna represented only by surface traces, gelatinous zooplankton, small-size organisms (〈 1 cm) and organisms that could not be identified at least to the phylum level. Frequency of occurrence at transects of different taxa was evaluated. Agassiz trawls were taken next to the photographic transects to obtain specimens for verification of taxonomic identifications based on images. In areas of stations 8 and 9 the thick ice prevented trawling operations.

    Checklist of the trawl macrofauna from the North Pacific and adjacent seas with information about fishery importance, potential product yield, and price range (2019)
    PANGAEA
    In:  Supplement to: Volvenko, Igor V; Orlov, Alexei M; Gebruk, Andrey V; Katugin, Oleg N; Ogorodnikova, Alla A; Vinogradov, Georgy M; Maznikova, Olga A (in prep.): Trawl macrofauna of the Far-Eastern Seas and North Pacific: proportion of commercial species, potential product yield, and price rang.

    Description: A checklist of 1541 animal species from the Chukchi, Bering, Okhotsk, and Japan seas and the North Pacific Ocean was generated from 459 research vessel surveys (68903 trawl tows) from 1977-2014 at depths from 5 to 2200 m. The study area spanned over 25 million km2. For each species, the scientific name is given, as well as English and Russian common names along with the following details: areas where species were collected, trawl type (benthic/midwater), real or potential commercial importance, possible product yield and minimum wholesale prices. The checklist can be used for development of bioresource management, aquaculture and conservation, assessment of environmental damage caused by anthropogenic impact (hydro-technical constructions, oil/gas extractions, nuclear reactor accidents, etc.).
