    Beschreibung: Relative abundances (%) of dinoflagellate cysts from sediment trap samples from the Belcher Islands Archipelago, south-eastern Hudson Bay, Canada between April and July 2019 using an automated Gurney Instruments Baker-style, cylindrical sediment trap (aperture 0.032 m2). The sediment trap was deployed at 40-m depth, 30-m above the seafloor and the rotation for the trap was set to 8-day intervals. Dinoflagellate cyst quantifications were done using a light microscope (Zeiss Axio Imager.A2 upright research microscope, University of Helsinki) with bright-field optics at a x600 magnification.

    Beschreibung: Datasets collected during a field campaign in the Belcher Islands Archipelago, Hudson Bay, Canada, during spring and summer 2019 including sea ice, water column, sediment trap and surface sediment samples that were analysed for diatoms, dinoflagellate cysts, highly branched isoprenoid lipids, pigments and geochemistry. The sea ice samples were collected using a Kovacs Mark II core barrel with an internal diameter of 9 cm, and the bottom 5 cm of the sea-ice cores were used for analysis on each sampling day. The water sampling was conducted using a plankton net (Ø 18 cm, 10 µm, 30-m net haul; diatoms) and a 2,5 L Kemmerer water sampler (pooled sample from 2.5-, 5-, 10-, 15-, 20-, 25- and 30-metre depths; highly branched isoprenoid lipids). For sediment trap samples, an automated Gurney Instruments Baker-style, cylindrical sediment trap (aperture 0.032 m2) was deployed at 40-m depth, 30-m above the seafloor and the rotation for the trap was set to 8-day intervals. The surface sediment sample was collected using a Kajak-Brinkhurst gravity corer. The under-ice salinities and temperatures were measured by using with RBR Concerto® and CastAway-CTD® sensors.
