## Methods ### Study area This dataset is the result from sampling at 6 stations across the Polar Front in the western part of the Barents Sea. ### Time coverage The samples were collected between 19 May 2022 and 25 May 2022. ### Sampling 11 macrozooplankton samples were collected with a Tucker trawl (1 m2 opening and 1500 μm mesh size) and towed for 10 minutes at ca. 2 knots. The targeted depth at each station was determined from the sound scattering layer identified in the echogram from the vessel's echosounder. ### Sample analysis Relative abundance from the Tucker trawl samples were analyzed per station, and taxa were counted and dried at 60 C° in pre-weighted recipients for dry weight measurements. The obtained abundances were standardized and converted to catch per unit effort, expressed in milligrams per cubic meter.Sampling Description
