Nunavut fishermen report a seasonal harvest totaling over 165,000 pounds of key fish species, with DFO data confirming the figures and underscoring ongoing community fishing activity.

Grey whale carcasses found along British Columbia and Washington coastlines this year suggest a link between warming seas, reduced prey in the Bering/Chukchi feeding grounds, and the species’ rapid decline. Researchers urge designation as endangered to protect the remaining populations.

Scientists find that reductions in Arctic sea ice alter the amount of CO₂ the Ocean absorbs each year, with the region accounting for 2%–9% of the global marine carbon sink.

The U.S. National Park Service offers practical steps for anglers in four Alaskan parks to limit mercury intake, such as choosing certain species and cooking methods, helping protect visitor health while preserving Arctic fishery resources.

New research shows Arctic peatland areas are growing further north as temperatures rise, potentially increasing the region’s capacity to store carbon while signaling broader ecological shifts from climate change.

The U.S. Department of War’s Ted Stevens Center for Arctic Security Studies and the Army Cold Regions Research & Engineering Office announced the International Cooperative Engagement Program for Polar Research (ICE‑PPR), a partnership aimed at broadening international scientific collaboration on Arctic research.

A new methodology offers transparent energy modeling for Arctic bidding zones lacking data, highlighting significant wind resource potential that could shape future electricity markets.

The 2026 ESSAS Annual Science Meeting highlighted how accelerating borealization is altering marine ecosystems, human‑nature relationships, and economic dynamics across the Arctic and Subarctic.

Melting sea ice and other stressors are driving a catastrophic mortality event that has cut the Pacific gray whale population from about 20,000 in 2019 to fewer than 13,000 today. With an estimated 2,500‑8,000 deaths this year, environmental groups urge NOAA to relist the species under the Endangered Species Act while the Trump administration threatens to ignore the request.

Permafrost thaw is undermining the ground that supports Arctic military installations, threatening their stability and operational reliability.

The ARAON icebreaking research vessel has departed for an 83‑day voyage across the Arctic, gathering in‑situ data that will support development of new polar shipping corridors while advancing studies of climate change impacts and seafloor conditions.

Araon completed an 83‑day mission in the Arctic Ocean, gathering on‑site data on Atlantic water encroachment and the first measurements of gas hydrates that will feed AI models guiding future Korean shipping routes.

Researchers recorded a late‑summer phytoplankton bloom in an Arctic fjord, attributing it to sediment-laden melt from nearby tidewater glaciers and influx of Atlantic waters that reduce light penetration.

A late‑summer phytoplankton bloom in Kongsfjorden on the western Svalbard coast was linked to an influx of warmer Atlantic water, offering new insight into fjord ecosystem dynamics.

Norway had been helping to oversee Soviet nuclear sites in the Arctic for a quarter‑century, but Russia’s recent war has broken that international cooperation and left the broader legacy unmanaged.

The study shows that a summer polar cyclone boosts surface winds in the Arctic, triggering Ekman pumping that lifts dense water and creates a density front in the Amundsen Basin, highlighting how atmospheric events shape subsurface ocean structure.

Scientists from the Arctic and Antarctica will meet in a joint session to compare meroplankton biology across both polar seas, aiming to better understand how these organisms respond to climate change and influence regional food webs.

Scientists warn that rising Arctic temperatures could make 2026 one of the deadliest years for West Coast whales by shrinking prey populations and forcing whales into more hazardous feeding areas.
