Observations

Erosion continues along Noatak River
High water throughout the summer continues to erode the river bank.

High water around Kotzebue
Above normal temperatures in the month of November followed by a series of storms makes varying ice conditions.
Kotzebue, Alaska, United States

Rain continues to impact Noatak River
Heavy rains have elevated river levels throughout August and September. High water continues to erode the river bank in the community. The photos show a tree that was 22 feet from the edge is know 3 feet. Total erosion has reached 91 ft. by old landfill and new mark shows 112 ft. marker.

High water in Kotzebue Sound
Water floods the Kotzebue lagoon. Grasses can be seen in July and a month later in August the water has risen 4-6 ft.

Highwater brings dramatic erosion
The river in Noatak is slowly cutting away parts of the road. This is an on going problem and the observation by Jeffrey Luther provides the latest in a series about erosion and related impacts.

Erosion Impacting Vegetation and Roads
This post is an update on the river erosion situation in Noatak, where a new channel is being cut by the Noatak River.

Noatak Erosion and River Channel redirection
As the river changes and erosion happens along the banks, new channels are being formed around the community.

Up river effect from Typhoon Merbok
The heavy rains and high water from storm Murdok today and Monday are contributing to the erosion of the old landfill and river bank.

Sudden lake draining event
"The event occurred on June 29th, on our native allotment near Kotzebue (Illivak). We left home in the morning and when we came back around 8:00 PM in the evening the whole lake had drained! It looked like it was blown up with dynamite."

Huge section of river bank collapses in Noatak
The collapse was documented with drone imagery as was a permafrost rebound signature in the river water.

River erosion threatens road
Noatak has lost 19' of river bank since May 19th. Now the road to the community gravel source is failing.

Still very cold on Noatak

Bank erosion exposing old landfill contents
A fisherman was coming home from fishing last night and noticed (what he thought was) a coffin sticking out of the old gravesite above one of the markers I used to measure erosion with last summer. It turned out to not be a coffin, but rather an old air duct or metal meat trailer.

High water this summer changes travel on Noatak River
"This year we had a lot more rain than other years, we used to be able to get on our ATVs and travel 10-12 miles upriver. I haven't seen or heard of anyone using ATVs to travel upriver this year. I think the breakthrough channel has a lot to do with us not being able to travel on ATVs. I see a lot of my favorite ATV fishing spots washed away from the highwater."

Bank erosion putting community water wells and transmission line in danger
Community Water System at Risk: Extreme precipitation throughout the summer and sustained high water has resulted in erosion of the location for the water transmission line and Noatak's two water wells.

Rapid Erosion Exposes Old Landfill
Unusual high water all summer in Noatak, causing massive erosion towards the airport and old buried landfill, exposing old trash into the river.

Downstream Erosion after Heavy Rain in Brooks Range
Photos show some of the erosion caused by surge of high water in late June on the Noatak River. As of June 29th, 24 feet of bank have been lost adjacent to the Noatak Airport, and 28 feet adjacent to the landfill.

As Arctic warming accelerates, permafrost thaw hits Alaska mine
The multinational company that operates the Red Dog Mine in Northwest Alaska says that thawing permafrost linked to global warming has forced it to spend nearly $20 million to manage its water storage and discharge.

Erosion and High Water in Noatak
High water in the Noatak River causes erosion near the old dump site.

Bizarre ice balls found in Arctic Alaska river puzzle locals and scientists
Danny Foster and Mike Hawley of Kivalina were ice fishing outside of town when they came upon something they’d never seen before. Incidentally, similar ice balls or ice eggs were reported on an ocean beach in Finland on the same day.

The river is very low and affecting well water quality
Low water on the Noatak River may be the reason behind changes in the water quality in community wells. The water quality began to change in the plant as measured (eventually) by the need for twice as much chlorine and Naclo polymer in order to get an acceptable residual of chlorine. The change indicates that the well recharge had been depleted and the that wells began operating on stored water in the aquifer. This water would have been older, likely anaerobic and higher in organics and in inorganics such as iron and manganese.

Short-tailed Shearwaters (Ardenna tenuirostris) Found on Chukchi Sea Beach
More than 50 birds and a seal were found along the shoreline.

Weird weather brings flooding to Kotzebue
The flooding was caused by a weather system that moved up to the Bering Sea from the tropics, and raised water levels and dumped rain across much of western Alaska.

Little Ice for Bearded Seal (Erignathus barbatus) Hunting
Because of the increased travel distance, only families with larger boats were able to participate in the hunt and bring back enough to make the trip cost effective. With a heavier load in the boat, one family ran out of gas trying to get home and had to be rescued.

Aftermath of Nov. Storm at Kivalina

Storm Surge
A strong storm impacting NW Alaska with high winds and sea level rise (over 6 ft) caused localized flooding in Kotzebue.
