Kiwi crews exposed to radiation at Mururoa Atoll hold concerns for subsequent generations.

Scientists say worsening heat waves have a clear link to climate change. This year, a seasonal El Niño pattern will also be adding fuel to the fire.

Beluga whales in Cook Inlet have been in a long period of decline, about two percent a year. But a new population count points to a reversal. The latest numbers have led researchers to declare the population stable for the first time in decades.

A long-running television show, "Alaska Weather" unique to Alaska that provides detailed weather, aviation and marine forecasts across the state will stop airing at the end of June. Especially in rural communities where many residents rely on the show for weather and safety information that's vital to coordinating flights and planning subsistence hunts or commercial fishing trips.

A research project found that the Bering Strait is at least a meter deeper on the Alaska side than previously believed, according to the National Oceanic and Atmospheric Administration’s Alaska Fisheries Science Center. The project evaluated new and old bathymetric surveys, applying modern technology to the latter to more accurately pinpoint locations.

As the Fairbanks North Star Borough continues to tweak plans to improve air quality in its nonattainment zone, its wood stove change-out program continues to grow.

$513,000 was vetoed in state budget that would have looked into the origin of salmon caught by the Bering Sea pollock fleet.

As king salmon decline in the Bristol Bay region, changes to king salmon harvest include reduced bag limits, area closures, as well as the introduction of youth-only fisheries in the Naknek River.

Knik Tribe officials have found very high levels of the toxin which causes paralytic shellfish poisoning in samples from Southern Alaska mussels and clams — but they warn that parts of some fish, including king salmon, may also contain the toxin

A federal appeals panel issued a last-second ruling Wednesday that will allow this summer’s Southeast Alaska troll chinook salmon fishery to open as scheduled July 1.

The Bureau of Land Management, in partnership with the Salcha-Delta Soil and Water Conservation District and Trout Unlimited, are restoring mining-impacted streams along the upper Yukon River watershed. Projects will improve water quality and fish habitat along Nome and Wade Creeks.

It’s been a week since ice severed a fiber optic cable in the Arctic Ocean, cutting communications to several Northwest Alaska communities.

This film is for young people and anyone in the Northwest Arctic who is curious about how (and why) to siifish, and how to process the fish after catching.

Northern Europe is experiencing an unusual heat wave and drought, making the region more vulnerable to forest fires, with firefighters battling wildfires in Portugal, Spain, Croatia, and southern France, and temperatures expected to hit 86 degrees Fahrenheit in Finland, rare for a country straddling the Arctic Circle.

During the 1970's much of the Norwegian coastline was overfished. In the past, a kelp forest provided shelter and food for local sealife. Today, the seabed, along the Norwegian coastline is a sea urchin desert. Researchers, volunteers, and the "Kelp Keepers" in Tromso, are removing the sea urchins and rebuilding the kelp forest.

"Global-mean surface air temperatures for the first days of June 2023 were the highest in the ERA5 data record for early June by a substantial margin", said Copernicus. Some of the unit's data goes back as far as 1950.

Dispersants may break up an oil slick, sparing some birds and wildlife at the surface, but may increase the oil contamination for species that live lower in the water column. The toxicity of dispersants themselves is also a concern for cleanup workers and other wildlife. A group of Alaskans filed a lawsuit in 2020 to force the EPA to rewrite the rules to take into account research on the long-term effects of dispersants in Prince William Sound and elsewhere.

Now, for the first time, researchers have concrete evidence that northern pike could use the ocean to move between freshwater Alaska habitats.

Biologists and others are hoping that a new phone app will encourage Alaskans to help map fish species living in the state's rivers and streams.

A group of Indigenous communities from Alaska and B.C. has declared a state of emergency related to Pacific salmon populations, and says First Nations need to be more involved in managing traditional resources.
