Regional Assessment of Deep Water Seabed Geohazards for Oil Spill Prevention
Amundsen ScienceA deep water (100 to 1500 m), continental slope-focused field program was carried out over four years, covering the eastern, central and finally, the western Beaufort Sea regions during survey expeditions in 2011, the western Beaufort in 2012, and 2014. This…

Dinoflagellate cysts from Hudson Bay sediment, 2005
Amundsen ScienceSediment cores were collected onboard the CCGS Amundsen during ArcticNet cruise 0502 (2005) using a box corer, penetrating the seafloor to a maximum of 50 cm. Samples were stored in a freezer (- 20 °C) onboard the Amundsen until the end of the cruise, then…

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…

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…

Seasonal and Late Holocene changes in export productivity as recorded in sediment traps and seafloor sediment collected in the Nares Strait
Amundsen ScienceHistorically, pack ice advected southward from the Arctic Ocean became congested in the narrow passages (e.g., Smith Sound) of the Nares Strait where it formed an ice arch. This ice arch sharply defines the northern boundary of the North Water polynya, which…

Multimedia contaminant survey during the Amundsen 2005
Amundsen ScienceMonitoring survey has been achieved during the Amundsen 2005 cruise through continuous measurement of total gaseous mercury (TGM), speciated Hg species (Hg°, RGM and PM), ozone and other gases (CO, CO2 and CH4), and media sampling of pesticides.

Investigating the Sources, Abundance and Types of Microplastics in the Arctic, 2018
Amundsen ScienceMicroplastics pollution has been found across the globe, but with limited information from the polar regions. Although there is evidence of microplastics in the Arctic and Antarctic, little is understood about the sources, fate and extent of contamination. We…

Functioning of benthic hotspots versus coldspots ecosystems in the Canadian Arctic
Amundsen ScienceSamples 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…

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…

Hydrocarbon concentrations in Baffin Bay sediments and benthic invertebrates (NGMP ID EC13)
Amundsen ScienceSample collections were made aboard the CCGS Amundsen during the ArcticNet field campaigns in August 2013 (Leg 1), July, August and October 2014 (Leg 1 & 3) and October 2015 (Leg 4). Sediment samples retrieved from box cores were sliced into 0.5 cm increments…
