Die-offs of krill are in some cases associated with hypoxia (low oxygen) excess sediment suspended in the water column and changes in water temperature. There were recent reports of high levels of Alexandrium in water samples in the areas, and Norton Sound Health Corporation is performing some testing of krill samples (see below). There was also an unprecedented storm event only a week ago, unusual for the storm surge and early season.

Ali Ralson was riding her 4 Wheeler towards Cape Blossom and came upon a beach full of fish. It appears that most of the fish are stickleback although there may be other species involved too. This would suggest an environmental issue that would impact multiple fish species rather than a pathogen. One potential cause could be harmful algal toxins.

The City and Borough of Juneau on Tuesday began the multi-day process of cleaning up after a Monday night landslide in the area of Gastineau Avenue.The landslide damaged three homes and displaced residents, but there were no injuries reported.

During a community meeting, Chevak residents said better emergency planning should be a long-term priority. For now, though, assessing damage is the focus.

Kivalina has long dealt with climate change-driven erosion. While the village didn’t feel the effects of heavy flooding, residents are wary of a future with heavy autumn storms.

“Our shipping monitors clocked another cruise ship going at excessive speed near Pond Inlet,” posted Baffinland Iron Mines on their Twitter account Sept. 22. While the maximum speed was agreed at nine knots in some passages used by the cruise ships, one ship in particular, The Hanseatic from Hapag-Lloyd Cruises, was clocked at almost 16 knots, nearly twice the velocity. It’s the second time this month the cruise line has been clocked in excess of the speed limit agreement.

The number of sockeye returning to Klukshu, Yukon, to spawn began to drop off in the 1990s. This year, hundreds of the bright red fish line the small creek that winds through the village. Neither the Champagne and Aishihik First Nations nor Fisheries and Oceans Canada are sure why the fish have returned after decades of steady decline.

Permafrost is ground that stays frozen year round; the permafrost in interior Alaska also has massive wedges of actual ice locked within the frozen ground. When that ice melts, the ground surface collapses and forms a sinkhole that can fill with water. Thus, a thermokarst lake is born. At first glance, Big Trail looks like any lake. But look closer and there's something disturbing the surface: bubbles.

Nome's landscape is physically altered, with raw material scattered wildly, the coastline reconfigured, and camps that anchored generations of subsistence either flattened or gone.

The storm could have threatened the town’s winter subsistence stock if not for the work of local power plant operators.

Several communities in the Norton Sound are struggling with contaminated drinking water days after the significant September storm hit the region.

The erosion of the Old Russian Cemetery from the impacts of the storm Merbokis also an unfinished process. The earth is actively moving, falling onto the beach bit by bit and sometimes in large chunks every day, to reach a state of stabilization after the storm.
