Overview of the Expedition
The CCGS Amundsen, a Canadian Coast Guard research icebreaker, embarked on a significant four-week mission on September 4, 2023, to study the rapidly changing sea ice conditions in the High Arctic, specifically around the Queen Elizabeth Islands and western Tuvaijuittuq. This area, known for its year-round sea ice, has become increasingly accessible due to climate change, allowing scientists from Fisheries and Oceans Canada (DFO) and the University of Manitoba to conduct comprehensive oceanographic research for the first time.
Findings on Sea Ice Conditions
During the expedition, researchers, including David Babb from the University of Manitoba’s Centre for Earth Observation Science, observed a notable decline in the thickness and extent of sea ice. The thickest ice encountered was approximately seven meters, a rarity in the region. Babb noted a shift towards more seasonal ice, which is thinner and more prone to melting, compared to the historically prevalent multi-year ice. This change is indicative of the Arctic warming at a rate four times faster than the global average, with projections suggesting the potential disappearance of Arctic sea ice within this decade.
Community Engagement and Local Impact
Despite the expedition occurring hundreds of kilometers from the nearest Nunavut communities, such as Grise Fiord and Resolute Bay, the implications of the research extend southward, affecting larger fisheries. The team engaged with local students during a science day at Qarmartalik School in Resolute Bay, sharing findings and discussing the presence of mercury and phytoplankton in the ocean. Grade 11 student Kupaaq Idlout expressed surprise at the varying salt concentrations in different areas, while teacher Rhonda McKenzie highlighted community observations of changing ice conditions, noting that elders reported faster melting and altered travel patterns on the ice.
Future Research Directions
The researchers aim to involve community members in future studies, encouraging them to assist in measuring ice thickness during their time on the land. Babb emphasized the value of local knowledge, stating, “They have these intangible observations that we can't collect.” This collaborative approach seeks to enhance understanding of the Arctic environment and its ongoing transformation due to climate change.
Official Statements & Responses
The DFO characterized the expedition as a pivotal opportunity to gather data on an understudied region of the Arctic. Babb remarked on the expedition's significance, stating, “This allows us to sort of understand what is happening in this area right now and guide projections on what is going to happen into the future.”
Criticism & Opposition
While the expedition has been met with enthusiasm from the scientific community, some critics argue that the focus on research may overshadow the immediate needs of local communities affected by climate change. Concerns have been raised about the potential disconnect between scientific findings and the lived experiences of Indigenous peoples in the region.

- “We have lost ice, we have increased the area of open water, and the area is now more navigable ,” — David Babb, Research Associate, University of Manitoba
- “Some of the elders have told me that the ice is melting faster and that they could have traveled by sled to certain islands or places longer into the year … but now it’s kind of different,” — Rhonda McKenzie, Teacher, Qarmartalik School
- “They live on the land, they live on the ice, they spend a lot of time on the water.” — David Babb, Research Associate, University of Manitoba
