Structure and resilience of the benthic food web across the Canadian Arctic and the Chukchi sea

The study area extends from the North Water Polynya to the Chukchi Sea across five geographic regions: North Water Polynya, Canadian Archipelago, Amundsen Gulf, Beaufort Sea and Chukchi Sea (14 stations). We collected data from July to October 2014 aboard the CCGS Amundsen including environmental data (bottom water temperature and salinity), particulate organic matter, sediments, and benthos. Stable isotopes analyses were practiced on benthic samples, particulate organic matter samples and sediments samples. Lipid extraction and ice algae biomarker analysis were practiced on benthic samples and sediments samples.

Purpose

The objectives of this study were (1) to describe the trophic structure and resilience of regional benthic food webs using stable carbon and nitrogen isotope analyses, and (2) to evaluate the significance of ice algae in the diet of benthic communities using the sea ice proxy IP25.
