Description
Summary:This dataset contains the Latin names and literature-based broad trophic and feeding occurrence (in terms of category of feeding depth zone) characteristics of 809 taxa recorded in the Barents Sea during scientific surveys by the Institute of Marine Research (IMR, Havforskningsinstituttet), Norway during the summers of 2014, 2015, and 2016. Trophic level (TL), functional group/guild (FG), broad group (e.g. mammal, fish, benthos), and depth group (DG, category of feeding occurrence to pelagic, benthopelagic, or benthic) were classified either directly from literature or based on e.g. congeners / similar organisms in similar areas with similar feeding habits. Each taxon is fully referenced, when relevant. These samples were taken during the annual IMR Ecosystem Surveys in the Barents Sea, and on surveys under the TIBIA (Trophic Interactions in the Barents Sea) and SI_ARCTIC projects. These surveys aim to monitor the organisms present, their geographic locations, abundance and biomass, and spatio-temporal changes to these in the Barents Sea ecosystem. Data were collected by pelagic and demersal trawls, and by plankton surveys.
