• Fast Repetition Rate Fluorometry-based measurements of non-photochemical quenching in Arctic phytoplankton assemblages

  Amundsen Science

  Non-photochemical relaxation experiments were conducted by introducing seawater samples (~3mL) to a Fast Repetition Rate fluorometer (FRRF; Soliense Inc.) optical cuvette. Samples came either from underway seawater lines onboard oceanographic vessels, or were…

• Sedimentation of organic material in Hudson Bay

  Amundsen Science

  Free-drifting, short-term particle interceptor traps were deployed from the CCGS Amundsen on eight occasions between 23 September and 16 October 2005. The traps were deployed at two or three depths below the euphotic zone (from 25 to 150 m) for 8 to 20 h. The…

• Fine-scale time series of surface dimethylsulfide concentrations across ice-covered and ice-free waters of the Canadian Arctic Archipelago in summer, 2017

  Amundsen Science

  This study presents sea surface concentrations of marine dimethylsulfide (DMS) measured across the Labrador Sea and the Canadian Arctic Archipelago during summer of 2017 (July-August). Using a novel automated instrument (ACT-MIMS) more than 2500 DMS…

• Seasonal study of nutrients and organic matter in first-year sea ice on the Mackenzie shelf

  Amundsen Science

  First-year sea ice was sampled on 36 occasions near the overwintering site of the CCGS Amundsen during the Canadian Arctic Shelf Exchange Study (CASES). Sea-ice and associated surface water samples were taken every 3 to 5 days between 24 February and 20 June…

• Incidence of light and ocean acidification on microbial community, dimethyl sulfide, dimethylsulfoniopropionate and macronutrients in Baffin Bay, Nunavut, Canada

  Amundsen Science

  An incubation experiment was conducted on board of the Canadian research icebreaker CCGS Amundsen between 6 and 15 August 2015. The water was collected near the nitracline at 38 m depth in Baffin Bay using 12-L Niskin-type bottles deployed on a CTD rosette…

• High-resolution survey of marine dimethylsulfide (DMS) in contrasted marine environments of the Canadian Arctic during the 2016 oceanographic ArcticNet/NETCARE campaign

  Amundsen Science

  The Arctic Ocean in summer is thought to be a nexus of biogenic dimethylsulfide (DMS) production associated, in part, with diversified niches within or bordering dynamic sea-ice where DMS-rich microbial communities may thrive. However, critical uncertainties…
