Underwater forests, such as kelp forests, have been found to cover a large area and have the potential to absorb significant amounts of carbon dioxide, making them important in addressing the climate crisis, although more research is needed to understand their long-term carbon sequestration capabilities.

Alaska’s Western Arctic Caribou Herd population is lower than at any time in over four decades. Climate change is the leading cause of the decline in the herd.

The Arctic Sounder - Serving the Northwest Arctic and the North Slope

Three temperature records this week were broken in Chukotka. Forecasters recorded abnormally high temperatures for this time of year in Pevek and Omolon.

Dozens of once crystal-clear streams and rivers in Arctic Alaska are now running bright orange and cloudy, and, in some cases, they may be becoming more acidic. This otherwise undeveloped landscape now looks as if an industrial mine has been in operation for decades, and scientists want to know why.

The North Slope offers a marginal place for a moose because far fewer willow shrubs grow there than in the boreal forest. Moose are recent invaders of the North Slope due to climate warming and expanding willow growth.

Alaska’s longest and most popular hunting season ended early this year. The Delta Junction bison hunt usually extends from October to March, but the state limited this year’s season to just two weeks, and only 50 animals were taken, because last winter’s heavy snow and ice buildup wiped out nearly a third of the Delta bison herd.

The Arctic hamlet of Tuktoyaktuk, N.W.T., is collapsing into the ocean as it loses up to a meter of coastline each year. The people who live there are in a race against time to preserve their way of life — and their community — before it is washed away.

Garbage and wood were removed by the municipal services of the village of Rytkuchi of the Pevek urban district from the coastline and tundra near the settlement. This was the final stage of a large-scale clean-up, which began in the summer after a strong storm.

There are new signs that killer whales, which are swimming farther north and staying for longer periods of the year in Arctic waters, are increasingly preying on Alaska’s bowhead whales. A newly published study found that 2019, an especially warm year in the region, also seems to have been an especially dangerous year for bowheads.

Some Southeast fishermen skipping fall season entirely, other’s say season has been “hit or miss”

As the driest summer in Seattle’s record books ended, trees across the city were sounding silent alarms. It was the latest in a string of Seattle summers in the last decade, including a record-breaking heat dome in 2021, to feature drier conditions and hotter temperatures that have left many trees with premature brown leaves and needles, bald branches and excessive seeding –- all signs of stress.

The recent closure of the Bering Sea snow crab and Bristol Bay red king crab fisheries has some Western Alaska towns taking a hard look at their futures, including St. Paul.

Three weeks after ex-typhoon Merbok hit Western Alaska and breached the Nome-Council Road, Department of Transportation crews and local contractors finished their repairs.

Researchers have detected striking changes in narwhal migration times driven by climate changes in the North. "Our long-term dataset identified that passage boundary crossing dates were associated with changing sea ice dynamics as a result of climate change," the researchers said in their paper p

For the first time ever, the Bering Sea snow crab fishery will not open for the upcoming season. The Bristol Bay red king crab fishery will also be closed for a second year in a row.

Alpine permafrost is thawing, according to an article by the National Science Foundation. This is bad news because thawing releases carbon dioxide and methane and because it can cause destabilization of the land, as a couple of northbound drivers found out last week when their car was buried in the slide at 23 miles, as reported in a Chilkat Valley News article.

Iñupiat communities have been looking for alternatives to traditional ice cellars. Some households switched to using manmade freezers, which can be effective but they affect the taste and the quality of the food, Nelson said. Additionally, power outages, frequent in the villages, can make this storage method unreliable. So the search is on for creative ideas to preserve traditional ice cellars.

A study – now in its eighth year – has found a remarkably diverse diet among the region’s wolf population. Sea otter has become a primary source of food.  

Southeast Alaska’s wolves tend to favor deer and moose at mealtime, but in a pinch they won’t say no to black bear – or even sea otter.
