Dissolved organic carbon distribution in the Canadian High Arctic, fall 2006
Amundsen ScienceThe distribution of dissolved organic carbon (DOC) in the water column of the Canadian High Arctic was investigated in 2006, as part of the ArcticNet program. Summer-fall DOC concentrations were measured at 27 stations between 4 September and 17 October 2006.…

Annual dynamics of bacterial biomass and production in Franklin Bay, western Canadian Arctic
Amundsen ScienceMicrobial and environmental variables were collected from 8 depths at a 200-m deep site in Franklin Bay on 33 occasions, from 4 November 2003 to 6 August 2004, aboard the CCGS Amundsen. The following variables were measured: depth, temperature and salinity…

Benthic biodiversity in relation to environmental variables in the Canadian Arctic
Amundsen ScienceBenthic fauna were sampled at 78 stations between June and October from 2007 to 2011 onboard the Canadian research icebreaker CCGS Amundsen. Station depths ranged from 34 to 1024 m, all below the average ice scouring zone. All faunal samples were collected…

Optical properties and carbon fluxes of the Eastern Canadian Arctic Ocean
Amundsen ScienceApparent and inherent optical properties (AOPs and IOPs), stock measurement of seawater samples and particles and fauna distribution profiles with an Underwater Visio Profiler (UVP) were studied from July 8 to August 14 (Leg 1) mainly in the Labrador Sea,…

Organic Carbon characterization from Hudson Bay sediments, determined by Rock Eval Pyrolysis
Amundsen ScienceSediment from Hudson Bay was collected with boxcores deployed from the CCGS Amundsen. The boxcores were immediately sectioned at 1 cm (top 10 cm), 2 cm (10 cm to 20 cm depth), or 5 cm (depth 20 cm) intervals, and aliquoted for a variety of analyses. Sediment…

Total Mercury and Methylmercury Profiles in Multiyear Sea Ice in the Southwestern Beaufort Sea
Amundsen ScienceReplicate cores spanning the entire thickness of the floe were taken from a single sampling site on a multi-year sea ice floe in the southwestern Beaufort Sea in August 2011 as part of the ArcticNet 2011 cruise of the CCGS Amundsen. Quantification of total…

A Canadian Arctic SOLAS Network
Amundsen ScienceWe are seeking answers to two key questions regarding the influence of marine processes on Arctic climate: 1) How will the increased flow of Pacific waters through the Canadian Archipelago affect the dynamics of climate-active gases in the ocean, and 2) How…

Water quality in southern Hudson Bay, mid-summer 2010
Amundsen ScienceWater samples were collected at approximately 0.3 m depth at all stations in Hudson Bay during the the 2010 cruise from Kuujjuarapik, PQ to Churchill, MB. We collected samples at basic, mooring and CTD (conductivity-temperature-depth) stations, as well as…

Sedimentation of organic material in Hudson Bay
Amundsen ScienceFree-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…

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