Pteropod abundance and shell dissolution in the Canadian Beaufort Sea/Amundsen Gulf

The Beaufort Regional Environmental Assessment-Marine Fishes Project (2012-2014) and Canadian Beaufort Sea-Marine Ecosystem Assessment (CBS-MEA, 2017-present) conducted by Fisheries and Oceans Canada provide offshore surveys of marine fishes and ecosystems on the Canadian Beaufort Shelf and slope in August and early September. The projects focus on integrating oceanography, food web linkages, physical-biological couplings and spatial and inter-annual variability, within the context of ongoing climate-driven change including enhanced Ocean Acidification. Sampling was conducted from the F/V Frosti at stations along transects spanning 20-1000 m. Zooplankton was collected using a bongo or multi-net system in conjunction with oceanographic and biogeochemical sampling.

Purpose: Pelagic sea snails, Limacina helicina, are an indicator species for the study of Ocean Acidification. Limacina helicina abundance and biomass data is presented from 2012-2017 for Mackenzie Shelf and Amundsen Gulf locations in the western Canadian Arctic. Shell dissolution extent is described for pteropod shells collected in the Amundsen Gulf in 2014 and 2017.
