Scientists from the University of Alaska Fairbanks have observed an increase in chum salmon spawning in North Slope rivers, potentially indicating a shift in their population and a signal of climate change. Elizabeth Lindley, a Ph.D. student working on the project, says that while evidence of spawning in a new region may be a positive for salmon, the impact on important subsistence resources including Arctic char and Dolly Varden is uncertain.

Drained lake basins make up more than half of the Arctic coastal plain, but the complete drainage of a lake is rarely witnessed by people.

"The fish was easy to mold on the drying rack because the hot summer sun was not coming through the smoke."

In early October 2013, local fishers Eli Nukapigak and Edward Nukapigak Jr. alerted wildlife officials to the discovery of “sick fish” in their nets near Nuiqsut. The aanaakłiq had fuzzy grayish-white patches on their bodies, fins, and heads. Cottony masses almost covered the eyes of some fish. None of the fishers in the community recalled seeing this condition before.

The varnished wooden cross stands amid a cluster of grave markers tilted at odd angles in the cemetery, because the ground beneath them is sinking. Rising temperatures are thawing the once-frozen earth, forming pools of water that run through the graveyard.

There seems to be a large red fox population in the region around Nuiqsut, Alaska. When I last traveled there for work, I counted 5 red fox during a 1.5 hour-long car ride.

The incident appears similar to an oil and gas release in 2017 blamed on thawing permafrost and hot production fluids.

The skin lesion in the photo is likely caused by a stress-related bacterial infection – possibly trauma initiated. Probably common opportunistic bacteria in the environment such as motile Pseudomonas/Aeromonas Gram-negative organisms.

An Alaska company says changing ice conditions in the North Slope area have allowed it to make a bulk fuel delivery to Prudhoe Bay by barge for the first time.

Questions raised about the impacts of vehicle exhaust and soot on snow deposition as well as dirt and dust from roads.

Human-polar bear interactions are part of life in Arctic communities, but as melting sea ice forces polar bears onto dry land, they are becoming more common and potentially more dangerous. This is the message of a recent scientific paper. Listen now

Melting permafrost causing tundra to slip below sea level in northern Alaska.

In northern Alaska, an amphitheater of frozen ground thaws where a northern river cuts into it, exposing walls of ice. The feature, known by scientists as “yedoma,” is the largest of its kind yet found in Alaska. A great wall of ice holds a lot of treasures from the past, which science is eager to explore.

The leak was detected early Friday at the drill site CD1, 8 miles north of the village of Nuiqsut. “There are no reports of injury or environmental impact to the tundra or wildlife,” the company’s statement said. “Air quality continues to be monitored and no natural gas has been detected outside of the CD1 pad.” The gas leak happened below gravel, and its cause and scale are under investigation, Conoco said. The company said it is using natural gas detection monitors at the CD1 pad, and conducting infrared surveys from the air.

Quintillion reconfigured the network and temporarily restored service as of Tuesday afternoon, the company’s president said. The break happened in an area with ongoing oil and gas maintenance and development.

North Slope facilities in Alaska closed due to severe blizzard conditions with winds up to 75 mph and low visibility.
