Climate-induced habitat changes on Alaska's North Slope such as coastal erosion and permafrost thaw have produced more food for migrating brant, a study says.
A parasite-riddled seal afraid of the water is the first Alaska marine mammal rescued in 2017. The seal will not be returned to the wild if it continues to survive rehabilitation at the Alaska SeaLife Center in Seward.
The celebrity glacier on the Kenai Peninsula, though relatively small and getting smaller, looms large in the public consciousness.
As sea ice off Alaska continues its long-term vanishing trend, two seal species that depend on ice may be showing the effects in their bodies. Ribbon seals, distinctive for their black-and-white striped patterns on their fur, and spotted seals, known for their speckled coats, became thinner over time.
One of the largest caribou herds in North America has declined by nearly a quarter in the past two years, hitting a population level that justifies new hunting restrictions. The news was delivered last week at the annual meeting of the Western Arctic Caribou Herd Working Group, an advisory organization with representatives of villages dependent
For decades, the crowds of small, dark sea geese on the tundra of southwestern Alaska's Yukon-Kuskokwim Delta have been thinning, a situation opposite that of geese on the North Slope.
Black brant populations are struggling in the species' once-dominant Yukon-Kuskokwim Delta breeding areas, but conditions are better for brant breeding on the Arctic coastline.
More polar bears on land have been encountering more people in the Arctic, a perfect storm of dangerous conditions, one scientist says.
Smoke and soot from central Alaska wildfires have afflicted the subarctic city of Fairbanks with some of the world's worst air pollution in recent days, forcing many residents indoors and prompting one hospital to set up a "clean air shelter."
New research shows that permafrost soils hold massive quantities of mercury — nearly twice as much as is held in all other soils in the world, plus the mercury in the oceans and the atmosphere —
As Alaska warms and permafrost thaws, the chemistry of the Yukon River's water is transforming chemically, new research from the U.S. Geological Survey shows.
Sleeper sharks are already known to range as far north as the Chukchi Sea, but reports of possible shark attacks on seal and sea lions have increased — and now come from further into the Arctic.
The notoriously difficult-to-study Pacific walrus population decreased by about half between 1981 and 1999, likely due to hunting and changes to sea-ice habitat, according to a new USGS study that is considered the most up-to-date and comprehensive so far. The Pacific walrus is being considered for Endangered Species Act protections.
A new study quantifies the rate at which Eklutna Glacier is losing its icy mass. Between 1957 and 2010, the loss of glacier mass averaged 5 percent a year.
Canadian researchers learned that local Inuvialuit hunters had spotted beavers in the region in 2008 and 2009. Those sightings are the first documented signs of North American beaver occupancy on the Beaufort coastal plain.
Elodea, an aggressive invasive plant, was discovered this month in the lake used by hundreds of floatplanes, raising fears that it will be spread to multiple sites within flying reach.
The elusive animals use snow caves to give birth and nurture their young. Just how much spring snow they need is not yet known.
A mysterious disease, possibly a virus, has afflicted ring seals along Alaska's coast, killing scores of them since July, local and federal agencies said on Thursday.
The North Slope Borough will have access to help with recovery efforts for the autumn storm that pummeled the coastline earlier this year, causing more than a million dollars worth of damage.
