Summary: | This dataset provides bulk stable isotope values of carbon and nitrogen for benthic fauna and some zooplankton collected in the Barents Sea during five sampling campaigns during 2018-2021; August 2018, August 2019, December 2019, March 2021 and May 2021. Benthic epifauna were collected using a Campelen or beam trawl and infauna were collected using a box corer. During the 2018 sampling campaign, zooplankton was also collected using a Harstad trawl. Upon collection, all fauna were sorted and identified to the lowest taxonomic level possible while in cold water. Muscle tissue was sub-sampled from large taxa while small taxa were kept whole. All samples were frozen at -20°C until further analysis. In the laboratory, samples were thawed slightly to allow for sub-sampling as needed, then freeze dried for 48 hours. After freeze drying, samples were ground to a fine powder using a mortar and pestle and approximately 1mg of sample was packed into tin capsules for isotopic and elemental analysis. For taxa containing ... |
