Scientific teams aboard the research vessel Oden report steady progress in ice studies, conducting fieldwork at scheduled stops throughout the Arctic Ocean.

Melinda Webster’s research shows the Arctic is warming at a rate four times the global average, highlighting rapid climate change in the region.

MIT drilled 3.6 ft of Arctic ice with magnetic sensors that return data autonomously, showcasing a new method for ice monitoring ahead of Operation Ice Camp 2028.

Satellite and aerial imagery reveal North American beavers expanding into Arctic regions, marking a new wildlife disturbance that may alter local ecosystems.

Freshwater released by melting glaciers in East Greenland’s fjords and coastal shelf is now feeding two major Arctic currents, showing that glacier melt is reshaping ocean circulation in the region.

MIT Lincoln Laboratory researchers are conducting studies in the Arctic, focusing on sensing, security, and climate science, and collaborating with other partners.

The Institute for Climate Dynamics and Climate Change at the University of Hamburg released an updated Arctic melt‑pond fraction dataset, adding the July 2‑4, 2009 area‑fraction data for sea ice. This update enhances the dataset’s temporal coverage, aiding researchers studying Arctic sea‑ice melt dynamics.

The feature follows scientists on a cutting‑edge research vessel as they study Arctic marine animals that can live more than two centuries, providing new insights into the region’s ecological resilience.

Wildlife biologist Robyn Thomas investigates how winter conditions along Alaska’s coast—from Kodiak to the Aleutian Islands—affect the emperor goose, a species whose breeding grounds on the Yukon Delta National Wildlife Refuge have been well studied but whose wintering ecology remains largely unknown.

The 40‑day voyage of the factory trawler Berlin in the Barents Sea highlighted the crew’s dependence on catch shares and exposed a critical factory outage that left the ship idle for almost seven hours. A scientific observer’s delayed treatment underscored the harsh operational conditions faced by Arctic fisheries.

The study documents that rapid climate change is causing plant community shifts and permafrost thaw in sub‑Arctic palsa mires, underscoring how these coupled changes could diminish Arctic biodiversity and carbon sequestration.

Long‑term cloud condensation nuclei data collected at Pallastunturi and a second Finnish sub‑Arctic site enhance understanding of aerosol‑cloud interactions in the high‑north, supporting climate modeling efforts.

New study shows that wildfire, permafrost thaw and wetlands in Canada release extra greenhouse gases that could raise global warming by 20–30% beyond current models, underscoring the need to revise climate budgets and policy targets.

Scientists have identified a new eel‑like fish species in the Arctic Ocean’s abyssal zone below 1,500 m, where it congregates around hydrothermal vents. The find adds to the limited catalog of just 17 known fish species in these harsh, inaccessible depths.

A study quantifies how the Canadian Arctic Archipelago channels trace metals and nutrients from Pacific‑ and Atlantic‑derived waters into Baffin Bay and onward to the Atlantic Ocean, highlighting the Arctic’s role in marine biogeochemistry.

Scientists tracked Arctic char, lake trout, Greenland cod and marine sculpin using acoustic telemetry near Cambridge Bay, Nunavut, to observe their behavior and habitat use, advancing knowledge of fish health and ecosystem dynamics in the region.

The study finds that thermohaline staircase layers above Atlantic Water in the Arctic Ocean persist over decades, indicating long‑term stability in Arctic stratification.

Satellite imagery shows a rare Arctic ice tongue that had been absent for years has reappeared, illustrating that while global warming continues to shrink overall sea ice, certain regions can experience temporary recoveries.

ELSA project will launch Arctic Future pilot studies in spring 2027, aiming to advance research on the Arctic operating environment and sustainable development.

The NNA‑CO’s recent initiatives in the Arctic emphasize coproduction and Indigenous partnership, using Indigenous Pavilions at Arctic Science Summit Weeks to build relationships and highlight the importance of inclusive research as funding for the program approaches its end.

Researchers depart from Vancouver or Quebec City, flying to Ottawa, Iqaluit, Arctic Bay, and finally Resolute Bay as part of a scientific expedition to the Arctic edge.

Beyond Arctic PASSION has officially launched, aiming to build a coordinated Arctic Observing System of Systems that will help monitor and address challenges across the region.

WormFEST will map Arctic worm forests to establish baseline data that will support sustainable management of deep sea ecosystems.
