A newly published study shows the presence of chemical pollutants in marine mammals and reindeer hunted by St. Lawrence Island villagers.
The temperature on the delar of Svalbard has risen to twice as fast as the time period known. No can forecast at the Norwegian Meteorological Institute document the greatest warming in the world.
On Thursday, for the first time, the sheen was reported in Krestof Sound, an area where Pacific herring are known to spawn in the spring.
Researchers documented the formation of new, irregularly shaped, steep-sided depressions. The largest was an oval-shaped depression 28 meters (92 feet) deep, 225 meters (738 feet) long, and 95 meters (312 feet) wide. The research team attributes these changes to intermittent seafloor collapse due to the gradual warming of the permafrost sediment frozen beneath the Arctic Shelf since the end of the last ice age.
With marine heat waves helping to wipe out some of Alaska’s storied salmon runs in recent years, officials have resorted to sending emergency food shipments to affected communities while scientists warn that the industry’s days of traditional harvests may be numbered. Salmon all but disappeared from the 2,000-mile (3,200-kilometer) Yukon River run last year.
When hurricanes cause both extreme high tides and heavy rains, devastating floods ensue. Such storms will get much more frequent by the end of the century, according to a new study.
The Skagway Traditional Council is asking harvesters to avoid blue mussels until the population rebounds.
The troublesome shipping on the Northern Sea Route continues into the new year. Almost three weeks after the world's most powerful icebreaker arrived in the Chukchi Sea, none of the four vessels stuck in the area have broken out of the ice.
In 2021, the average temperature in Norway was normal, while precipitation was 10 percent below normal. The year is nevertheless marked by great contrasts. The summary of the weather in 2021 was presented at the Meteorological Institute's annual event Climate Status on 5 January. Here you can see video footage of Climate Status (Vimeo)
Deglaciation could increase salmon habitat by nearly 30% in the Gulf of Alaska by 2100.
It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route. After a month of icy captivity and subsequent icebreaker rescue, a convoy of nine vessels this week made it to safety in the Kara Sea. On December 7, a Russian nuclear icebreaker completed
The lab tests samples from 17 communities in Southeast, as well as from tribes on Kodiak Island.
Never before at this time of year have so many vessels been rescued out of the ice, says Russia's nuclear icebreaker operator Rosatom. It has been an Arctic odyssey for the ships and crews that in November got stuck in sea-ice on the remote Northern Sea Route.
Landslides and tsunamis aren’t historically common in Glacier Bay, but because more than half a million visitors tour the park each year park managers want to get a clearer picture of the risks of tsunamis and landslides, which have become more common recently due to a changing climate.
Multiple fish populations in the Bering Sea have experienced a slight decline, according to the 2021 Bottom Trawl survey.
Majestic, increasingly hungry and at risk of disappearing, the polar bear is dependent on something melting away on our warming planet: sea ice.
Since bottom water temperatures have been warming drastically across the Northern Bering and Chukchi Seas over the last few years, cysts are now growing locally in Arctic waters. The blooms carry toxins, but scientists aren’t yet sure what impact they will have on marine mammals.
Protecting the coast of Tuktoyaktuk from the onslaught of climate change is estimated to cost at least $42 million and is only guaranteed to last until 2052. Over the project’s 30-year lifespan, over 60,000 cubic metres of sand are expected to be brought to keep the beach intact.
Seal meat makes up a good portion of what’s in subsistence hunters’ freezers in Kotzebue. But the sea ice the seals haul out on is diminishing, and new research shows that's shortening the window to hunt seals.
