Alaska researchers are developing a method to detect landslide-triggered tsunamis, aiming to provide early warnings for such unpredictable events.

Sea ice loss, warming waters and the northward expansion of fish species like pollock are all contributing to a pattern in the Bering Strait region known as “borealization.” That means the Arctic ecosystem is becoming more like the boreal region to the south.

Alaska's new Sustainable Energy Action Plan aims to cut greenhouse gas emissions and promote renewable energy, excluding oil industry cuts.

The Alaska Arctic Observatory and Knowledge Hub and the Native Village of Kotzebue deployed an under-ice oceanographic instrument to monitor ice thickness and snow depth at a site offshore of town.

The Chemring Nobel explosive plant in Norway is increasing its emissions fivefold, raising concerns about worsening nitrogen pollution in the Oslo fjord.

The article discusses concerns over the impact of human-made noise on endangered Cook Inlet belugas and the debate over noise mitigation measures.

Alaska is set to receive $125M in federal funds for renewable energy projects, benefiting over 20 villages with solar, hydroelectric, and storage initiatives.

Scientists are investigating the widespread presence of paralytic shellfish toxins in Alaska's marine food chain, which may explain recent species die-offs.

NASA's PACE satellite, designed to study ocean biology in unprecedented detail, has been successfully launched to enhance understanding of Earth's changing climate and improve weather forecasting.

“It’s a reflection of the plastic age we live in," said student researcher Tony Blade. "It’s ubiquitous."

The new children's book combines traditional knowledge and scientific research to tell the story of a ringed seal pup in Kotzebue, Alaska, with a focus on the impact of climate change.

New Zealand's first mechanical suction dredge is being trialed in Northland to combat the invasive seaweed caulerpa, potentially revolutionizing marine biosecurity efforts.

Norway awards 62 new oil drilling licenses, signaling a push towards a 15-year peak in oil and gas production despite international calls for a halt in fossil fuel exploration.

Norway faces criticism from the European Parliament and environmental groups for its decision to allow mineral exploration in the Barents and Greenland Seas, despite concerns over potential ecological impacts and calls for a ban until proven safe.

Knik Tribe data reveals high levels of paralytic shellfish poisoning toxin in some Alaskan subsistence shellfish harvests, with variability in toxin levels across different locations.

A comprehensive analysis of over 200 studies reveals that fish hatchery programs have predominantly negative impacts on wild salmon populations, reducing genetic diversity and overall health.

A coalition of 38 tribes in Alaska received a $1.2 million federal grant to establish the 'First Indigenous Sovereign Habitat Tribal Conservation District' for co-management of federal lands from the Bering Sea to Interior Alaska.

A study reveals that increased ship noise in the Arctic disrupts the behavior and communication of marine mammals, impacting local wildlife and indigenous hunting practices.

Anchorage's climate action plan, adopted in 2019 to reduce emissions by 80% by 2050, has seen little progress and poor communication under Mayor Bronson's administration.

The U.S. State Department has expanded America's territory by defining the extent of its continental shelf, claiming an area roughly twice the size of California, mostly in the Arctic.
