UrduA new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.

Strongest Arctic cyclone on record led to surprising loss of sea ice
The strongest Arctic cyclone ever observed struck in January 2022. A new analysis shows that while forecasts accurately predicted the massive storm, models seriously underestimated its impact on sea ice. Results suggest places to improve forecast models in a changing Arctic Ocean.
Last ice-covered parts of summertime Arctic Ocean vulnerable to climate change
The region north of Greenland and the Canadian Arctic has been termed the “Last Ice Area,” where sea ice will remain the longest in summertime, providing a refuge for ice-dependent Arctic species. But conditions last summer show that parts of this region are already experiencing less summer ice due to climate change.
Record-high Arctic freshwater will flow through Canadian waters, affecting marine environment and Atlantic ocean currents
An unprecedented bulge of fresh water in the Arctic Ocean will travel through the Canadian Archipelago to the Labrador Sea, affecting local marine environments and global ocean circulation.
International research team begins uncovering Arctic mystery
According to 25 international researchers who collaborated on a first-of-its-kind study, frozen land beneath rising sea levels currently traps 60 billion tons of methane and 560 billion tons of organic carbon. Little is known about the frozen sediment and soil — called submarine permafrost
WHOI-NOAA partnership tackles critical gap in climate knowledge
Researchers at WHOI were recently awarded a $500,000 grant from the NOAA Climate Observations and Monitoring program to develop machine learning tools to improve estimates of air-sea heat exchange in the Arctic Ocean and adjacent seas.
Newer PFAS compound detected for first time in Arctic seawater
Researchers reporting in ACS’ Environmental Science & Technology have studied the transport of 29 PFAS into and out of the Arctic Ocean, detecting a newer compound for the first time in Arctic seawater.
A CARBON SINK SHRINKS IN THE ARCTIC
Ice melts in the Arctic Ocean were thought to draw large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research from the University of Delaware finds that may not be the case in all areas, particularly in the Canada Basin, where the melts are reducing the basin’s capacity to remove carbon dioxide from the atmosphere.
Increasingly mobile sea ice risks polluting Arctic neighbors
The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research from CU Boulder.
