title: Distribution of and feeding by the copepod pseudocalanus under fast ice during the arctic spring.
abstract: The arctic copepod Pseudocalanus can be highly aggregated in the first few centimeters under landfast ice during spring in concentrations up to 10/(6) per cubic meter. Chlorophyll-derived pigments in the water, the abundance of animals, and their gut pigment index show fluctuations that may be tidally related. Short-term grazing experiments performed at -1.7 degrees C, in which ice algae was used as food, yielded feeding rates comparable to the highest known for the genus. Arctic Pseudocalanus seem to feed opportunistically near the ice-water interface, either directly on the attached epontic (under ice) algae or as it erodes from the ice.
