The Bering Sea region, the Pacific gateway to the Arctic Ocean, is home to ecosystems on land and in the ocean that are both abundant and fragile. It’s also changing very quickly — and those changes offer a preview of the changes in store for other parts of the Arctic.

Residents of the Southwest Alaska village are hauling water from the Kuskokwim River, collecting rainwater and drinking donated bottled water as officials seek a viable option.

A decade-long warming trend in the Gulf of St. Lawrence continued in 2020. Water temperatures at depths of 200, 250 and 300 metres were higher than any measured in the Gulf since records started in 1915, hitting highs of 5.7 C, 6.6 C and 6.8 C. All were well above the normal variations.

The Haines Borough Assembly’s Commerce Committee began chipping away at a plan to address the borough’s bear problem at a meeting Tuesday. Proposals ranged from stronger enforcement of bear-attractant laws, to the development of education and grant programs to help people secure their attractants, to a complete overhaul of the community’s solid waste management system.

The Department of Civil Protection has raised the level of alert from Uncertain to Dangerous, due to a risk of avalanches. This morning it was found that an avalanche had fallen on the Skarðsdalur Ski area. Nine houses in Siglufjörður will be evacuated.

A new report from the Governor's Salmon Recovery Office shows salmon and steelhead populations in Washington state teetering on the brink of extinction. Five or the populations of salmon and steelhead listed a threatened or endangered, are in crisis.

Sitting in the Port of Dutch Harbor, the Polar Star is nearly 400 feet long and can break ice up to 21 feet thick. On Tuesday, the ship arrived for a pit stop with 136 crew members, 30 days into a months-long deployment to the Arctic. Their goal is to assert maritime sovereignty and security in the far north.

Cold temperatures and traffic congestion at the Panama Canal has resulted in a shortage of natural gas and exploding prices in parts of Asia. Now, Novatek aims to send LNG from the Arctic to Japan during the middle of winter in an untested high-risk, high-reward strategy. 

It will become clearer in the coming days how the sunken barge owned by Laxa aquaculture in Reyðarfjörður, East Iceland, will be re-floated after this weekend’s storm. Divers are working on the vessel again today and, so far, it appears no diesel or other oil has leaked into the sea.

The national weather agency reported that as of 7 a.m., the snowfall in Madrid reached a level unseen in half a century.

Bocaccio rockfish have made a huge comeback in B.C. since being deemed endangered in 2013, but the success story is being met with some trepidation as trawler fishermen can’t seem to avoid netting them now.

Permafrost in Canada's northwest is thawing much faster than researchers predicted 20 years ago, according to the president of the International Permafrost Association.

We examined the effects of temperature and salt concentration on growth of the freshwater oomycete Saprolegnia parasitica that has recently (since 2013) been found to infect an important subsistence fish (in Iñupiaq, Aanaakłiq; broad whitefish, Coregonus nasus) on the Colville River in Nuiqsut, Alaska. Using two confirmed isolates (one from the Colville River and another from a southern British Columbia aquaculture facility), we tested the following hypotheses: (1) the isolate from Alaska will grow at a greater rate than the isolate from British Columbia at lower temperatures, (2) the isolate from British Columbia will grow at a greater rate at higher temperatures than the Alaska isolate, and (3) increasing salinity will reduce the growth rate of both isolates similarly at all temperatures. In addition, we used local observations—subsistence fishers and observations asso- ciated with scientific monitoring—to assist in interpreting the potential implications of our experi- mental results in the context of these environmental observations. In the habitat relevant to this study, water temperature ranges between <0°C and 18°C, and salinity ranges between 0 and 30 parts per thousand due to a seasonal (and occasional west wind-driven) saltwater intrusions. No statistically significant differences were detected in growth rate or salt tolerance between the two isolates at the temperatures and salinities tested; high temperature (24°C) and low salt concentra- tion are associated with the highest growth rate for both isolates. From our lab study, one might conclude that the peak host colonization would occur during the seasonal period of warmest water temperature; however, the observations by local fishers and biologists show this not to be the case. We conclude that, at this time, we do not have evidence that peak warm water is the primary cause of an increased incidence of infection by this freshwater mold. Although indirect and lag analysis of temperature and timing of infection were not part of this study, we note that there is a greater role of complex interactions among biotic and abiotic factors (including temperature) that may predis- pose some individuals in the population to become infected during spawning season.

Mildvær har holdt de mest utsatt fjellovergangene i Finnmark åpne for trafikk hele desember. – Man må bare nyte det, sier trafikkoperatør.
