Diatom concentrations (valves/ml) from modern water column samples collected from the Belcher Islands Archipelago, south-eastern Hudson Bay, Canada between April and May 2019 using a plankton net (Ø 18 cm, 10 µm, 30-m net haul). Diatom quantification was done using a light microscope (Zeiss Axio Imager.A2 upright research microscope, University of Helsinki) with phase contrast optics at a x1000 magnification.
