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.”

Université Laval will receive $20.7 million from the Canada Foundation for Innovation (CFI) to support and broaden the scientific activities of the research icebreaker CCGS Amundsen over 2020–2023. The additional support will facilitate access to the Amundsen for the Canadian scientific community and international users, consolidate technical expertise for the deployment of cutting-edge instrumentation, and further support the renewal of scientific equipment that has reached its end of useful life. It also comprises operational funds to access, on an opportunity basis and non-interference basis with other Coast Guard programs, additional seagoing time.

And it’s a go!
It’s early this morning that the CCGS Amundsen left Quebec City for its 16th scientific expedition. The multidisciplinary expedition will run until October 24 and will allow a reduced contingent of scientists from national research teams to study the marine and coastal environments of the Canadian and Greenlandic waters.
Next step: a second mobilization in Dartmouth where will embark researchers from the Bedford Institute of Oceanography (BIO) and their scientific equipment.
For more details on the 2020 Amundsen expedition, read the Departure Press Release.
Stay tuned for more expedition updates and follow the ship in real-time!

In preparation for the departure of the 2020 Amundsen Expedition, Amundsen Science has developed a statement that explains our official position during the current COVID-19 pandemic.
We remain available would you like to obtain any additional information.
To all of our community, stay safe, and remain vigilant!

On Earth Day, Fisheries and Oceans Canada and the Canadian Coast Guard released Canada’s Oceans Now: Arctic Ecosystems, 2019.
The report summarizes the current status and trends of arctic marine ecosystems.
A very interesting read full of educational contents in these times of confinement.

“The Arctic is often referred to as the “canary in the coal mine” and the changes that happen there will have an influence on the global climate system as a whole, including the Maritimes and New Brunswick.”
Read this article describing Josh Evans participation to the 2019 Amundsen Expedition as a University of New Brunswick grad students.

Amundsen Science is very proud to share the work of Philippe Tortell, a longtime member of the Amundsen’s community and renowned oceanographer with more than two decades of experience documenting the effects of climate change on marine systems around the world.
To mark the 50th anniversary of Earth Day, Philippe edited a multi-disciplinary collection: Earth 2020: An Insider’s Guide to a Rapidly Changing Planet.
This book ”responds to a public increasingly concerned about the deterioration of Earth’s natural systems, offering readers a wealth of perspectives on our shared ecological past, and on the future trajectory of planet Earth. An essential reading for everyone seeking a deeper understanding of the past, present and future of our planet, and the role of humanity in shaping this trajectory.”

We had a very productive day here in Quebec City, refining the 2020 expedition plan and enhancing collaboration between science teams.
Thanks to everyone for making this workshop as efficient and collaborative!
Note: The 2020 Amundsen Planning Workshop has been held before the current sanitary measures related to the COVID-19 pandemic were implemented. See our Amundsen Science Statement for more details.

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»!
