As the Amundsen will proceed to its third crew change in Resolute Bay this Thursday, a solemn ceremony is planned on September 8, 2023, to commemorate the lives lost in a tragic accident related to the research icebreaker that happened 10 years ago.

On the afternoon of September 9 of 2013, the helicopter assigned to the research icebreaker was taken for an ice reconnaissance mission near McClure Strait. The helicopter pilot Daniel Dubé was accompanied by Marc Thibault, commanding officer of the CCGS Amundsen and Klaus Hochheim, a scientist from the University of Manitoba. All three of them tragically lost their life as the helicopter crashed about 600 kilometres west of Resolute Bay, Nunavut, abruptly putting an end to the scientific mission.

This incident deeply moved all of the CCG and Arctic science community. Marc Thibault, Daniel Dubé and Klaus Hochheim were three important and dedicated members of the Amundsen Expeditions as they took part in numerous cruises between 2003 and 2013.

Marc Thibault, Commanding Officer of the CCGS Amundsen

Throughout his career, Marc Thibault has served as Watchkeeping Mate, Chief Officer and Commanding Officer on Canadian Coast Guard (CCG) vessels. He graduated from the CCG College in August 1988. He spent 12 years as Commanding Officer aboard seven different vessels, and made 19 Arctic voyages.

Commander Thibault was an available, jovial, courteous and respectful man who demonstrated excellence during scientific missions with ArcticNet, resulting in worldwide visibility and renown for the expertise and professionalism of the CCG, and more specifically for the work carried out by the CCGS Amundsen. His loyalty to his crew and the organization, his 29 years of unconditional service to the people of Canada, and his contribution to Arctic scientific research are to be commended.

 

Daniel Dubé, Helicopter’s pilot

Daniel was an experienced pilot with 28 years’ experience piloting Canadian Coast Guard helicopters. Born and raised in Val d’Or, Quebec, Daniel obtained his helicopter pilot licence at ‘’Centre Quebecois de Formation Aéronautique’’ in Chicoutimi. After several years working in the private industry, he joined Aircraft Services as a Canadian Coast Guard pilot in 1985. Throughout the many things and missions, he has accomplished, Daniel was a great supporter of the scientific programs and a very interested man. On many occasions, he supported the Maurice Lamontagne Institute’s annual water sampling mission with the Bell 212. He also participated in many Arctic voyages aboard CCG ships. Of a note, he was part of the 2007-2008 International Polar Year’s voyage aboard the Amundsen as Pilot-in Command of the Bell 212. Daniel was qualified on the 3 helicopter types we had at the base.

For his colleagues, Daniel was a doer. He would always bring solutions to every problem. He was the wise man his peers and supervisors could always rely on for advice and help. For Daniel, his colleague from Transport Canada and the coast Guard were also part of his family. He was a great person to be around.

Klaus Hochheim, Scientist Affiliated to the University of Manitoba

Since 2005, Klaus Hochheim had worked with the Centre for Earth Observation Science (CEOS) contributing on various research projects about sea ice climatology and microwave and optical remote sensing of ocean-sea ice-atmosphere coupled processes. During the 2013 Amundsen Scientific Expedition, Klaus was at its seventh participation on board the research icebreaker, making him a precious scientific contributor and collaborator of the Amundsen. Klaus was very close to all his lab partner and for some of them he was also a mentor. His laugh and willingness to help, his ability to solve problems will be remembered.

 

 

 

 

We join our voice to the CCG, Transport Canada and to the scientific community to honour and pay tribute to those who have lost their lives during this fateful ice reconnaissance mission in the Arctic. A small gathering will be organized on September 8^th by the CCG and Transport Canada to remember M. Thibault, M. Dubé and M. Hochheim and their contributions during each of their respective careers.

 

We would like to thank the Canadian Coast Guard and Transport Canada for their collaboration on this article.

The Polarella glacialis is a species of phytoplankton, microscopic algae, that is present in both arctic and antarctic coastal and marine environments. This microscopic alga commonly found in first-year sea ice sinks to the bottom of the sea once the ice melts. A team of scientists analyzed marine sediment samples and found that the presence of DNA from the Polarella glacialis is linked with the concentration of sea ice observed. They were also able to find the same DNA in sediments dating from 12 000 years in northern Baffin Bay, which allows them to know what sea-ice concentrations were at that time! Their new method could provide insights on the sea-ice conditions that both poles faced over the last millennia. The paper describing this work by Harðardóttir et al. is currently under review at Nature Portfolio.

A data paper is a peer-reviewed document, which describes a dataset in a scholarly journal. It provides information on the data collection and quality control processes instead of formulation hypotheses and conclusions. As the organization managing the scientific mandate of the CCGS Amundsen, Amundsen Science is an important data producer of the Canadian Arctic marine ecosystem.

During the 122 days of the 2021 Scientific Expedition, the icebreaker sailed over 30 000 km across the Canadian Arctic and sub-Arctic, collecting sea surface, atmospheric and seabed underway measurements. Two hundred and sixty-six casts of the CTD-Rosette were also conducted to monitor the main physical, chemical and biological parameters of the water column. Various datasets collected by our organization during this cruise are presented in a data paper currently under review in the Earth System Science Data journal. This article by Ratsimbazafy et al. is a meaningful project on which a big part of our team worked on for the past years.

In this data paper, changes in salinity, temperature and oxygen can be observed through lines of stations across Davis Strait, in the North Water Polynya and near Cape Bathurst. Thanks to these lines of data, the authors were able to identify and highlight the most important water masses of the Canadian Arctic. The authors also presents bathymetric data collected in Smith Bay, at the terminus of Mittie Glacier. This area was previously unchartered; therefore, the safety and efficiency of future operations will be enhanced by this hydrographic survey. All the dataset presented by Ratsimbazafy et al. are publicly available, in agreement with Amundsen Science’s data policy. More information about the past cruises can also be found in the expedition reports and summaries.

Every year since 2003, the CCGS Amundsen welcome on board teams from Canada and abroad for Arctic multidisciplinary scientific expeditions. As the Arctic is a rapidly warming region, it is necessary to study this area in order to learn more about future climate trends and impacts. In summer 2021, between July 20^th and August 10^th, Judith Vogt was on board the CCGS Amundsen to measure the atmospheric methane (CH₄) levels continuously in a corridor between St. John’s (Newfoundland) and Iqaluit (Nunavut) in order to detect early signs of CH₄ release. In fact, vast amounts of CH₄ stored in submarine sediments are prone to being released as the Arctic warms. This release has the potential to intensify climate changes in a positive feedback.

From high-resolution atmospheric CH₄ measurements and discrete surface water samples, Judith Vogt’s team estimated instantaneous sea–air CH₄ fluxes at various locations. In addition, they measured CH₄ concentrations across the water column at various stations using the CTD rosette. In the northern Labrador Sea and Baffin Bay, the continuous measurements of atmospheric CH₄ levels in the northern Labrador Sea and Baffin Bay were consistently higher than the global marine average with small instantaneous input from the ocean. These findings indicate that variations in dissolved CH₄ concentrations were mainly affected by ocean currents and seafloor sources. However, atmospheric CH₄ levels showed interrelations with environmental factors, location, and time, with minor temporal fluctuations. Deeper investigation is required to validate potential sources of CH₄ and to elucidate the reasons behind the increased methane levels in the shallow-water region of Southwind Fjord, where recent landslides triggered by an iceberg were observed.

The CCGS Amundsen made her way back to Quebec City with new discoveries and stories to share ! After 40 days at sea from coastal Labrador Sea to Northern Baffin Bay, there were around 250 scientific operations that were realized: nets, ROV dives, moorings, CTD-Rosette, and much more.

“It has been an amazing experience see how all the different science disciplines come together during an expedition. It was also my first time onboard a research vessel, so it was very instructive to see how my work in ocean mapping relates to the work of the other teams.”

Graham Christie, M.Sc. Eng., Student in geodesy and geomatics engineering at University of New Brunswick.

The science teams and crew members had some challenges during the expedition, but they were able to work together and face those challenges to make the most of the 2022 Amundsen Scientific Expedition. Congratulations to all and welcome home !

Stay tuned for the Expedition report, it should be online in the next weeks.

The first Leg of the 2022 scientific Amundsen expedition is studying the coastal marine environments of Labrador Sea, from fish biology to chemistry cycles using various advanced technologies. The expedition is also a great training opportunity to learn about the Nunatsiavut and Inuit culture.

The five Inuit communities of Labrador are located on a territorial area called Nunatsiavut, which means Our Beautiful Land. The teams are very fortunate to have Michelle Saunders and Carla Pamak onboard, who both work for the Nunatsiavut Research Centre. In addition to helping with scientific operations, they continue to guide the research objectives of the expedition and to share their culture and history.

Nakummek! (Thank you!)

Quebec-Ocean announced today the recipients of different annual scientific publication awards. Among the awarded articles, we note the presence of two publications resulting directly from oceanographic campaigns carried out on board the CCGS Amundsen.

The 2021 Student Publication Excellence Award was given to Laure Vilgrain, a PhD student at Laval University. Using thousands of images collected by an advanced imaging system called Underwater Vision Profiler during the Green Edge campaign (CCGS Amundsen, 2016) and new analysis techniques, she documented how copepod life resumes with the return of spring sunshine and phytoplankton growth. It should be recalled that this research had also been nominated by the Sea Foundation and the Ocean Institute (France) in 2021. The full article is available here.

The 2021 Joint Publication Award was presented to Philippe Massicotte, research professional at Laval University for the Takuvik International Joint Unit, and to his numerous co-authors. The paper presents the results of a joint effort to compile and standardize data sets collected during the MALINA oceanographic expedition (CCGS Amundsen, 2009) to facilitate their reuse in other studies of Arctic Ocean evolution. The full paper is available here.

Congratulations to all!

Geological changes are usually perceived as processes taking place over long time periods. The comparison of multibeam data acquired over the last decade prove the contrary.

Paull et al. (2022) compared mapping data collected by an Autonomous Underwater Vehicle (AUV) during recent surveys with the mapping data acquired from the CCGS Amundsen in 2010 using a multibeam sonar. Their results reveal rapid morphological changes, such as the development of new steep-sided depressions up to 28 m in depth, associated with submarine permafrost thawing.

The spread and extent of these changes on the Arctic shelves is still unknown, as multiple multibeam bathymetric surveys are necessary to identify the changes. Rapid seafloor changes associated with submarine permafrost thawing may be an important process that requires further investigating.

Vessel traffic has been increasing in the Northwest passage, particularly in the newly established Tallurutiup Imanga National Marine Conservation Area. This important habitat for marine wildlife is seeing the greatest levels of vessel traffic in the Canadian Arctic.

In a paper published in Environmental Science & Policy, Halliday et al. (2022) modelled underwater noise levels and examined the overlap with the distribution of wildlife. In particular, they studied the impact of noise on two cetacean species (beluga and narwhal) and three seabird species (thick-billed murre, northern fulmar, and black-legged kittiwake). Conductivity-temperature-depth (CTD) measurements taken by the CCGS Amundsen during its annual expedition helped model underwater noise levels.

This study identifies the regions where greater risks are presents for the wildlife species and provides information and suggestions for implementing monitoring, conservation, and management initiatives. Of the five species studied, narwhal had the greatest high-risk area (Eclipse Sound and Milne Inlet).

After more than 115 days at sea, five Legs and hundreds of scientific operations, the CCGS Amundsen is finally back to it’s home port of Quebec City. Congratulations to all research teams who took part in the 2021 Expedition!

Many thanks to the Canadian Coast Guard and the Canada Foundation for Innovation for their support.

Stay tuned for the result of this Arctic mission.

A team of scientists studied the nutrient transport pathways in the lower St. Lawrence Estuary using results from the 2018 Odyssée St-Laurent winter mission. The mission provided the first winter turbulence observations, which cover the largest spatial extent ever measured in the area during any season.

Scientists previously assumed that the estuary’s surface layer received its nutrient supply from vertical mixing processes. On the contrary, Bluteau et al. found that fluvial nitrate inputs are the most significant source of nitrate in the estuary. The authors also provide seasonal perspectives on the nutrient transport pathways.

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.

The paper was published in Nature Geoscience on June 24th.

The 2021 Expedition has begun!

On June 4th, the CCGS Amundsen left Quebec City for its 17th annual scientific mission. The multidisciplinary expedition will run until November 3rd and will allow a contingent of scientists from national and international research teams to study the marine and coastal environments of the Canadian and Greenlandic waters. From aquatic microorganisms to carbon cycle to melting glaciers and seabed mapping, all aspects of the northern environment will be studied during the 122 days of the expedition.

A newly published collaborative paper studies the abundance and types of plastic pollution in surface waters in the Eastern Arctic (Inuit Nunangat) using data collected during the 2018 Arctic Expedition of Amundsen Science. The authors also provide insights on how to move the scientific work towards reconciliation while producing knowledge about environmental pollution.

Key findings are:

• Plastics are reported in surface water in SW Greenland (0.026/m2) & Tasiujarjuaq, Nunavut (0.014/m2)
• Recovered plastics show indications of both long-range and local sources.
• Surface water plastic research in Inuit Nunangat and Greenland is led by southerners and non-Inuit.
• “Reconciliation science” requires changes in personnel, methods, and communicating results.

New results from the GreenEdge Project were published earlier this year in the journal Limnology and Oceanography .

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.”

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.”

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.”

The 2020 Amundsen Expedition is taking shape!

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»!
