This dataset consists of lipid analysis, fatty acid analysis, and compound specific stable isotope analysis of δ13C values in fatty acids. These parameters were measured in three pelagic zooplankton (Calanus glacialis, Thysanoessa inermis, and Themisto libellula) and two sea-ice associated amphipods (Apherusa glacialis, Gammarus wilkitzkii). Zooplankton and ice-associated amphipods were collected on the R/V Polarstern PS106/1 (23 May - 21 June 2017) and PS106/2 (23 June - 20 July 2017) campaigns and on two R/V Helmer Hanssen polar night campaigns (4 - 16 January 2017 and 5 - 18 January 2018). See document details for the different types of gear used, which included Multinets, pelagic trawls, Surface Underwater Ice Trawls, and ROV nets. Organisms were collected north of Svalbard, the Barents Sea, and within the Nansen Basin of the Arctic Ocean. Lipid class analysis was conducted using high performance liquid chromatography. Extracted lipids were converted into fatty acid methyl esters, and quantified (via an ... : For the ROV net data, Date/Time refers to the start of the ice station. The start and end of the ROV net sampling can be found in the columns "Date/Time start" and "Date/Time end". ...
