Scientists found an enriched uranium particle over the Aleutian Islands and don’t know where it came from.
While reproductive failure is common for some species like black-legged kittiwakes, it isn’t for murres. In some places less than one percent of the chicks survived.
A small eastern Aleutian community is now getting nearly all of its energy from renewable sources. With a second hydro facility that began producing power late this spring, the city of King Cove has dramatically reduced its dependence on diesel.
Scientists are trying out crowdsourcing to comb through pictures looking for sea lions.
The novelty of seeing a jumbo squid in Unalaska is not wearing off: a second one washed ashore Monday night.
What has eight arms, two tentacles and washed ashore on a beach in Unalaska Monday night? A more than six-foot long squid.
There are plenty of seals in Unalaska, but ringed seals -- who make their homes on the ice -- are rare.
This November in Utqiaġvik was the hottest on record, averaging 17.2°F. It was so warm that NOAA's quality control algorithms flagged the data. “When we look out on the ocean right now we see a few icebergs,” Thomas said. “Normally we would see white to the horizon in the past, and in this case we’re seeing dark water to the horizon.”
Dead crowns in the canopy and rusty-colored branches are woven in with the otherwise healthy, green temperate rainforest. About a third of the trees around here were hit by the voracious sawfly. The larvae get mistaken for caterpillars. Adults are a kind of non-stinging wasp, a little smaller than a pinky finger.
An early melt-out date can make for an especially bad wildfire season, but this year, it’s right on schedule for much of the state. Listen now
"It was pretty crazy how much water just kind of showed up," said Michelle St. Martin, whose field season was cut short by melting sea ice.
According to Alyeska Pipeline Service Company, approximately 400 gallons of an oily water mix had been recovered from the Port of Valdez as of Saturday night.
Officials are still examining the substance in a lab to determine what it is, but DEC suspects it’s black tar or asphalt.
"These ridges that we’re standing on, there would have been more of them, and they would have been bigger," ice researcher Andy Mahoney said. "The features that we now see, they’re something of a shadow from the past." Listen now
As lichen has disappeared, the herd has changed its diet. This adaptation could have global implications for reindeer facing a warming climate.
One ecologist wonders, for the yellow cedar forests and the people who care about them, what comes after climate change and environmental loss in Southeast Alaska?
Biologists are investigating a surprising connection between two animals that aren’t exactly well loved in parts of Southeast. Gustavus locals suspect wolves are picking off deer at a popular hunting spot on an island near the mainland.
The Arctic’s like an air conditioner or refrigerator for the global climate...And as the Arctic warms, partly because the sea ice is going away, it’s like you’re opening that refrigerator door.
“It’s an area that I and some other colleagues have started thinking about: can you get methane forming in terrestrial environments? But it’s a very new area of science,” carbon scientist Katey Walter Anthony said.
Ocean acidification threatens some of Alaska’s most lucrative crab fisheries. But there’s one ray of hope: it’s possible that crabs might be able to adapt to the changing oceans. The big question scientists are researching at Bob Foy’s lab in Kodiak is – will they have enough time?
