The health survey Qanuilirpitaa? (How are we now?) was carried out in 2017, when the CCGS Amundsen was transformed into a clinic to visit the 14 communities of Nunavik. A team of 40 people was on board for seven weeks to collect health data in the region in order to improve programs and services.
The documentary Qanuilirpitaa? How Are We Now? broadcasted on Absolutely Canadian follows the interviewer Lydia Audlaluk through this survey which addresses sensitive subjects and revives painful memories for some, but also allows finding solutions.
The results of the health survey are available here.

Members of the PeCaBeau team boarding the CCGS Amundsen for Leg 4 are publishing a series of short field blogs to explain their work and the life onboard the ship.
“[A deep corer involves a] 9-m long core barrel, which holds 9 m of plastic liner inside, is attached to 800 kg of weight on top of it. […] A core with such a length of several meters may contain information about climate and environmental history of several thousands of years. Maybe right into the last ice age.”
See below for the complete list of field blogs, which will be updated as field blogs are posted.

A combination of satellite imagery and bathymetric surveys shows that a submarine landslide caused by the grounding of an iceberg occurred in Southwind Fjord in 2018. Bathymetric data from the CCGS Amundsen was used to identify other locations where grounding of icebergs could have caused submarine landslides. These results show that icebergs are hazardous over a great distance away from their source of origin and can affect the development of marine infrastructures.
Repeated surveys are key to identify this type of natural hazard. “Unlike the terrestrial environment where satellites take images every few days, it is very rare to have annual images of the seabed, especially in the Arctic”, says Alexandre Normandeau, researcher at Natural Resources Canada. He and a team of scientists will participate in the 2021 Expedition to survey the area again, map the morphology of the landslide with Amundsen Science’s ROV and study the benthic ecosystem recovery.

PhD Student and corresponding author Laure Vilgrain explains:
“During the GreenEdge cruise in June and July 2016 aboard the CCGS Amundsen, an advanced imaging system named ‘Underwater Vision Profiler’ was deployed at more than 150 stations across the ice-edge. Hence, zooplankton organisms measuring between 0.7mm and few centimeters were taken in photos in their natural environment, under the ice and in ice-free waters.
Researchers from Université Laval and from the Laboratoire d’Océanographie de Villefranche-sur-Mer (France) used these images in an original statistical analysis to study how the morphology (size, color) and posture of copepods (active or resting) vary in response to ice melt and phytoplankton spring bloom. The insights from this study are useful to better understand copepod ecology in relation with sea ice dynamics, in particular because these organisms are key components for fish, birds and marine mammals in Arctic food webs.”

Scientists from St. John’s published a new study in the PLOS ONE journal using samples obtained from the CCGS Amundsen. They analyzed environmental DNA to monitor deep-sea fish diversity in the Labrador Sea. This technique called eDNA metabarcoding might help scientists for implementing sustainable management efforts as well as understanding the impacts of commercial fishing and climate change.
Dr. Mehrdad Hajibabaei comments:
“Characterizing biodiversity is key for ecological and environmental investigations. In this study we used environmental DNA from seawater samples to identify various fish species living in one of the most challenging and understudied ecosystems, deep waters of the north Atlantic in the Labrador sea. We were able to optimize and demonstrate the utility of eDNA analysis by comparing our results with a combination of conventional tools such as trawling, baited camera traps and hydroacoustic analysis. This study was possible largely due to an excellent collaborative framework especially access to DFO’s expertise and CCGS Amundsen’s capabilities for sampling in this remote and challenging waters.”

Water mass distributions were mapped throughout the Canadian Arctic Archipelago (CAA) through the use of Radium isotopes collected in the summer of 2015 aboard the CCGS Amundsen as a contribution to the NSERC-CCAR GEOTRACES project.
In a recent paper, published in the Biogeosciences journal, authors shed new light on the dominant water mass patterns in the area, including the bulk Eastward current and the effects of the prominent coastal shelf system, which is responsible for inhibiting Atlantic waters within the CAA. In addition, they were able to show that against the bulk eastward transport Atlantic waters intrude the CAA from the east, which then, in a “U-turn”, are reflected back into Baffin Bay. As the area provides the North Atlantic with the cool waters necessary for deep water formation, gaining better knowledge of the water mass distribution in this region is imperative.

Through deployments of robotic ice-avoiding profiling floats from the CCGS Amundsen between 2017 and 2019, researchers from Takuvik Joint International Laboratory demonstrate that net phytoplankton growth occurred even under 100% ice cover as early as February and that it resulted at least partly from photosynthesis. This demonstration is strongly contrasting with the popular belief wanting that Arctic marine phytoplankton cannot grow until sea ice and snow cover start melting and transmit sufficient irradiance to allow photosynthesis.
These results highlight ”the adaptation of Arctic phytoplankton to extreme low-light conditions, which may be key to their survival before seeding the spring bloom.”

”At any moment, approximately half of the world’s population is wearing blue jeans and other denim garments.”
University of Toronto’s researchers who sampled Arctic marine sediments from the Amundsen over 2014-2017 detected indigo denim microfibers. They found that one pair of used jeans can release about 56000 microfibers per wash. Their conclusion: ”blue jeans, the world’s single most popular garment, are an indicator of the widespread burden of anthropogenic pollution by adding significantly to the environmental accumulation of microfibers from temperate to Arctic regions.”

Through the years, a discrepancy between observed changes in the extent of the Arctic sea ice cover and the climate model predictions has been observed. To better understand how much heat flux increases from the ocean to the atmosphere and how it influences the melting of sea ice in the Arctic region, different sampling equipment are deployed by ArcticNet teams onboard the CCGS Amundsen. One of them, definitely the most aesthetic one, is the weather balloon.
Weather balloons are used to profile low-pressure systems, cyclones, and periods of significant warm or cold-air advection aloft.
It sure gives this sunset a little «je ne sais quoi»!
