Cold-water coral (soft corals and sea pens) sampling in Baffin Bay, Nunavut, 2017
Amundsen ScienceCoral samples were collected in Pond Inlet and Lancaster Sound in Baffin Bay using the CCGS Amundsen’s remotely operated vehicle (ROV). Samples from Agassiz trawl and box-core deployments were also kept as part of this study (11 stations). Samples were…

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

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…

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…

Trace element concentrations in the water column of the Canadian Arctic Ocean measured from the CCGS Amundsen in 2009, 2019, 2021, 2022 and 2024
Amundsen ScienceTrace metals in the ocean, including iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb) and vanadium (V), may act as micronutrients or toxins to marine phytoplankton and thereby directly impact primary…
