... date, two sets of sea-ice samples for biota were collected using a Kovacs Mark V 14-cm diameter corer and focusing on the bottommost 10 cm of sea ice where the bulk of ice biota are typically found ( Smith et al., 1990 ). The first set of samples were subsectioned into two intervals, 0–3 and 3–10 cm...
