• Bottom water samples for particulate organic matter (POM) carbon (C) and nitrogen (N) stable isotopic composition in Baffin Bay, Nunavut

  Amundsen Science

  Bottom water (20 L per station) was collected at 11 stations in Baffin Bay using the CCGS Amundsen’s rosette system. Water was filtered aboard the vessel into glass microfiber (GF-F) filters for Carbon and Nitrogen stable isotopic composition analysis. These…

• Benthic Diversity across the Canadian Arctic

  Amundsen Science

  Data were mainly collected from the CCGS Amundsen (2015 to 2019) and from the William-Kennedy (2019). An Agassiz trawl (1.5 m width × 0.7 m height, cod end of 0.5 cm mesh size) was towed on the seabed at a speed of 1.5-2 knots for 3 to 5 minutes to survey…

• Functioning of benthic hotspots versus coldspots ecosystems in the Canadian Arctic

  Amundsen Science

  Samples were collected from nine sites distributed across the study region in 2008 and 2009. To avoid confounding influence of seasons, the same sites were sampled in the same season each year. Sampling was conducted onboard the CCGS Amundsen between July and…
