Continued Arctic changes, 2014
During high school when the day promised heat I used to spend a minute in the morning to put sunglasses on my car. They were ‘shutter shades’, louvered sunglasses printed in bold lines on folded white cardboard meant to be spread just under the windshield. The car may not have contained power anything, a reliably […]
Lab fridge Arctic ground squirrels
“They do their best to approximate a sphere,” Loren Buck explained as he removed the ground squirrel from its lab-made hibernaculum. Hibernating Arctic ground squirrels can sustain a core body temperature of just -2.9°C [26.78°F]. “It’s cold… Do you want to touch it?” Buck uncurled the animal carefully. “He knows he’s being handled, it just takes a […]
Many angles to decode frozen debris lobes
“Something chewed on the casing,” Margaret Darrow explained. “Probably a bear.” Blue chips were scattered from the cracked ABS pipe. Inside the casings that protect the holes drilled in and around frozen debris lobe -A there’s non-toxic propylene glycol. Propylene glycol, this brand a clear greenish liquid, prevents freezing – helpful for scientific instruments – […]
Effective stress and FDL science
“It’s a very dynamic slope,” Margaret Darrow said, standing in front of frozen debris lobe -A. FDL-A is a slow landslide; among the frozen debris lobes documented it’s the closest to the Dalton Highway and the Trans-Alaska Pipeline. Although the lobes likely began their life as debris left over when Pleistocene glaciers disappeared 10 to […]

Imaging the future of Arctic plant life
If you know where to look in the Arctic, you’ll find strange hexagons dotting the tundra beneath the enduring summer sun. Strange, scattered honeycomb chambers. The open-top hexagonal units shelter 1 or 2 square meters’ worth of tundra plants, passively raising the temperature within their fiberglass walls by 1-3°Celcius.
Migration Over The Brooks Range
Even Wacky Weather doesn’t stop bird migration to Alaska. Scientists on the north side of the Brooks Range at Toolik Field Station find the birds which made it over the mountains have located their nests, indicating procreation has begun.
Mosquito netting, vacuum power, and bug science
Vacuuming at home isn’t too edifying. How about vacuuming the Alaska tundra to snag a bag full of bugs? That’s an entirely different story. Ashley Asmus, graduate research assistant at the University of Texas at Arlington, is using a huge reverse leaf blower to collect the bugs she’ll study.
Stressed out? Every year migratory birds battle stress, and win
On the tundra a wire walk-in trap has been placed over seed scattered atop icy Alaskan ground. A Longspur alights nearby. It twists its head to eye the seed, hops inside then briefly flaps – unsettled by the trap door closing behind it. The Longspur settles and eyes the ground again, beginning to peck. PhD student Jesse Krause, a researcher […]
Thousands of kilometers north – migratory birds and a shifting world

Ned Rozell for UAFGI – It’s not often that glaciologists help with the recovery of long-lost human remains, but military officials recently enlisted Martin Truffer for that purpose. The University of Alaska Fairbanks Geophysical Institute professor and graduate student Dave Podrasky came up with useful information on a Southcentral glacier that held plane wreckage and […]
Modeling Arctic Waters from the Bering Sea through the Bering Strait to the Arctic Ocean
Liz O’Connell for Frontier Scientists – Fairbanks, Alaska, September 4, 2012 – Three videos introduce the oceanographic modeling work from the University of Alaska Fairbanks (UAF). The video Modeling Ice in the Arctic, shows a regional ice model coupled with a global climate model. “The ice is not as stiff as it used to be,” said Kate […]
Fire is a natural part of the boreal forest ecosystem
Ned Rozell for UAFGI – With their mushroom clouds topped with cauliflower crowns, plumes from wildfire smoke are again a common sight in Interior Alaska, which — with barely a sprinkle of rain — just experienced one of the driest Mays in the 100-year written record. Though it’s a normal human reaction to think of […]
Arctic lakes getting a closer look
Ned Rozell for UAFGI – Minnesota is the Land of 10,000 Lakes, but Alaska has more than that in the great expanse of flatlands north of the Brooks Range. These ubiquitous far-north bodies of water — most of them formed by the disappearance of ancient, buried ice that dimples the landscape as it thaws — […]
Unmanned Aerial Vehicles (UAV’s) Fly in the Aleutians
August 14, 2012— Three videos detail the Unmanned Aircraft work from the University of Alaska Fairbanks (UAF). In March, Greg Walker, UAF’s Unmanned Aircraft Program Manager, led research in the Aleutians. Walker flies the UAVs in just about all conditions except freezing rain which would stick to delicate equipment. “We’ve regularly flown in showers, we’ve […]
Survey: Abrupt permafrost thaw increases climate threat
Marie Gilbert for UAF Cornerstone – As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates, according to survey results from 41 international scientists published in the Nov. 30 issue of the journal Nature. Permafrost thaw will release approximately the same amount of carbon […]
“This is not what we expected” said Julie Brigham-Grette in video describing work at Lake El’gygytgyn
July 10, 2012– “To this point no one has much of any terrestrial record anywhere in the Arctic older than 125,000 years ago” said Julie Brigham-Grette, University of Massachusetts Amherst as she describes findings from the Lake El’gygytgyn (or Lake E) project to Office of Polar Programs Board Meeting at the National Science Foundation. Brigham-Grette […]
Geologic methane seeping from thawing cryosphere
Geologic methane is seeping through the edges of thawing permafrost and receding glaciers in Alaska and Greenland, according to a study recently published in the journal Nature Geoscience. University of Alaska Fairbanks researcher Katey Walter Anthony led the study, which, for the first time, documents the widespread occurrence of these terrestrial sources of geologic methane […]
Flying machines for the dirty, dull and dangerous
Some places in this world are just too dirty, dull or dangerous for human pilots to fly. An airspace in the latter category is anywhere near gas flares in Alask’s oil fields. With only a few seconds of warning, flames blast high in the air from a network of pipes, releasing the stress of sucking […]
Unmanned Aircraft: Arctic science & technology
Speeding over Arctic sea ice, small remote-controlled aircraft snag video footage and high-definition shots of endangered Steller Sea Lions in their natural habitat. Quiet and unobtrusive, the machines can serve as Special Op.s for researchers. Low-altitude remote sensing using Unmanned Aerial Vehicles (UAVs) has vast potential… and we’re only beginning to explore it. Gregory Walker, […]
Wind-aided birds on their way north
After flying northward from Chile, a whimbrel landed in late March in an alfalfa field near Mexicali, Mexico. The handsome shorebird with a long curved beak left its wintering ground in South America one week earlier and flew more than 5,000 miles. Nonstop. In one of the great migrations happening all over the world right […]
Recovery after world’s largest tundra fire raises questions
Four summers ago, Syndonia Bret-Harte stood outside at Toolik Lake, watching a wall of smoke creep toward the research station on Alaska’s North Slope. Soon after, smoke oozed over the cluster of buildings. “It was a dense, choking fog,” Bret-Harte said. The smoke looked, smelled and tasted like what Bret-Harte has experienced at her home […]

Play in the dirt with Dig Afognak Laura Nielsen for FrontierScientists If uncovering archaeological treasures and exploring local culture appeal to you more than simple sightseeing, you’ll want to check out the Kodiak Archipelago the next time you can make it to Alaska. The Afognak Native Corporation’s program Dig Afognak has visitors, archaeologists, and Native […]
Tools of ancient Alaskans emerge from ice
Ned Rozell for UAFGI – On a late summer evening a few years ago, a scrap of birch bark caught William Manley’s eye as he walked along the edge of an ice field in the Wrangell-St. Elias Mountains. The geologist yelled to nearby archaeologist Jim Dixon and Ruth Ann Warden of the Ahtna Heritage Foundation. […]
Alutiiq basket weavers share insight with Russian curators
Fairbanks, Alaska, April 24, 2012 – “The Museum of Anthropology and Ethnography (MAE) and the Russian Ethnographic Museum in St. Petersburg Russia have the earliest collections of Kodiak baskets, grass and spruce root, in the world,” said Sven Haakanson, executive director of the Alutiiq Museum and Archaeological Repository. In 2010, Haakanson traveled with six Native […]
Memories from Lost Villages
Laura Nielsen for FrontierScientists World War II brought conflict and trial to Alaska. Unalaska, located in the Aleutian Islands, had served as a trading hub for local villages. Native people from Biorka, Kashega, and Makushin would bring goods like fox pelts and baskets via boat and hiking trail to Unalaska to trade. In June 4, […]
Alaska dune yields oldest human remains of far north
Ned Rozell for UAFGI – Last summer, archaeologist Ben Potter was supervising a group of researchers digging on an ancient sand dune above the Tanana River. Potter, who had a field camp he needed to start at another site, was anxious to get through the last day of work at the dune. Two graduate students, […]
Far-north permafrost cliff is one of a kind
Ned Rozell for UAFGI – In northern Alaska, an amphitheater of frozen ground is thawing where a northern river is cutting it, exposing walls of ice. The feature, known by scientists as “yedoma,” is the largest of its kind yet found in Alaska. Jim Helmericks, who lives with his wife Teena on the mouth of the […]
The longest non-stop migratory flight
LLiz O’Connell for Frontier Scientists – Early on Bob Gill, Research Wildlife Biologist with the U.S. Geological Survey (USGS), thought Bar-tailed Godwits’ journey from Alaska to New Zealand was a non-stop flight. Faced with skepticism from his colleagues, but armed with satellite technology, Gill tagged a female Godwit he named E-7. By tracking E-7 in […]
New videos about Permafrost, a blog about the Dog Mushing Weather Dance, and a video description of FLOPs
January 31, 2012– Permafrost is an underground phenomena but three new videos, with beautiful footage and photos, allow you to see permafrost with your own eyes. University of Alaska-Fairbanks scientists Vladimir Romanovsky, Sergey Marchenko, and Ronald Daanen describe permafrost in videos “It’s a Bore Hole”, “The Permafrost Tilted House” and “Permafrost Patterns”. We should get […]
Flowing tongues of rock, ice and dirt
Ned Rozell for UAFGI – A few years ago, Ronald Daanen was driving north of Coldfoot on the Dalton Highway, looking for drunken trees. He pulled over when he saw some tipsy spruce on a hillside. The University of Alaska Fairbanks scientist thought the tilted trees would be a classic sign of thawing permafrost, ground […]
One Mean Dance Partner: How Mother Nature Twirls the Sport of Dog Mushing
Kristin Knight Pace for Frontier Scientists – The brittle cold of Dead Dog Flats is enough to make my parka crinkle as I ladle out the hot mixture of fat and tripe, chicken protein and kibble. One by one the dogs emerge from their houses and, by the time I have gone through the whole […]
Satellite Tracking Helps Russian Tanker Navigate Critical Sea Duck Habitat
Matthew Sexson and Paul Laustsen for USGS – ANCHORAGE — On its way to deliver emergency fuel to Nome, Alaska, the Russian tanker Renda will move through an area used by wintering spectacled eiders, a federally threatened sea duck. But, to protect the ducks and their wintering habitat, resource managers from the U.S. Fish and Wildlife Service and navigators from the U.S. Coast Guard are […]
Into the southern Chukchi Sea
By Carin Ashjian for The Arctic Winter Cruise 2011 We are moving further south. As we go, the ice is filling the Chukchi Sea, filling that sea with us still in it. A few days ago, there was sea ice only in the northern part and along the coast. Now, as we go south, the […]
Sample, sample, sample…..
By Carin Ashjian for The Arctic Winter Cruise 2011 There is a sense of anticipation in the air. Tomorrow is Thanksgiving and we will be observing it, even though we are at sea in the Arctic. As luck would have it, we have a couple of long transits between stations to accomplish tonight and tomorrow […]
Thump, Shudder, Screech
By Carin Ashjian for The Arctic Winter Cruise 2011 We are in the thick of winter now. We have reached our furthest northern point, at 72 27.18 N, over the slope-basin in about 2000 m of water. As we moved north, the ice became thicker and more resilient. Sometimes moving is easy, sometimes we claw […]
Arctic Night
By Carin Ashjian for The Arctic Winter Cruise 2011 Today the sun did not rise. We have come so far north that we have reached a latitude where the sun did not come above the horizon on this winter day, where night lasted for 24 hours. We were treated instead to a few hours […]
Into the Ice
By Carin Ashjian for The Arctic Winter Cruise 2011 We are now, finally, in ice. The ship is shuddering along, not breaking ice but rather pushing floes of pancake ice aside. When occasionally we break into a lead of open water, the ship glides unfettered, seemingly not moving because there is no irregular bumping and […]
Through the Strait
By Carin Ashjian for The Arctic Winter Cruise 2011 This morning at around 1030 local time we passed through Bering Strait and into the Chukchi Sea. As we go, the air becomes colder, the water becomes colder, the sea is gray, and the winds are howling at 30 knots from the NE. We are […]
Tern Tail and Shark’s Tooth
Laura Nielsen for Frontier Scientists The Karluk One archaeological site, situated on the shores of modern-day Kodiak Island, Alaska, was exceptionally well-preserved. The location of an ancient settlement where Alutiiq people once resided, the site was occupied from 1400AD to 1800AD and held an abundance of astounding artifacts. Its location turned out to be unfortunate. […]
Alaska volcano observers kick serious ash
With active volcanoes as close as 80 miles of Anchorage city limits, Alaskans are grateful for the professional volcano watchers who work in a nondescript building on the campus of Alaska Pacific University, topped with a massive array of tracking and communication instruments. “The August 18, 1992 Spurr eruption, sent an ash cloud here that […]
Sharing a planet with volcanoes
The scientists at the United States Geological Survey – Alaska Volcano Observatory (USGS-AVO) in Anchorage, Alaska don’t only have an impressive title – volcanologists – they also pursue an engaging, challenging career. Alaska contains over 130 volcanoes and volcanic fields.
Old age: it’s all in your mind when it comes to geologic time
It’s just a matter of time before one of the volcanoes in the chain that lines Cook Inlet erupts. But time in geologic terms is a bit like the federal deficit; so vast in scope it’s hard to comprehend. The Cook Inlet volcanoes of south central Alaska are practically babies when it comes to earth […]
The Arctic videographer’s wildest card: the weather
Our plan: a two-day video shoot to Cape Alitak on Kodiak Island in May 2010 to document the petroglyphs under study by the Alutiiq Museum and Archaeological Preserve. We had the best possible guides–the head researcher studying the rock art, anthropologist Sven Haakanson and his museum crew–to help us complete the scripted story we wanted […]
Cross-Cultural Art, a view of the Cape Alitak Petroglyphs
Laura Nielsen for Frontier Scientists – At the southern end of Kodiak Island, like gems hidden among the rocks of Cape Alitak, you can find petroglyphs carved into stone. These petroglyps are engraved images of faces, people, animals, spirals and shapes. Sven Haakanson, the executive director of Alutiiq Museum, works to document these petroglyphs. You […]
Future Directions: Beyond Matcharak Lake
The 2008-2009 excavations at Matcharak Lake confirm many assumptions about the Denbigh people 4000 years ago. We have shown the Denbigh to be specialized caribou hunters at least when they are in the mountains. We have shown the extensive use of organics as tools and that these earliest of Paleo-Eskimos were skilled artisans. Although research […]
Excavations at the Hungry Fox Archeological Site, Gates of the Arctic National Park and Preserve
Excavations at the Hungry Fox Archeological Site, Gates of the Arctic National Park and Preserve by Jeff Rasic for Alaska Park Science – Gates of the Arctic National Park, spanning the central portion of the Brooks Range in northern Alaska, is filled with remote river valleys that are hundreds of miles from the nearest city […]
Thermal State of Permafrost in North America: A Contribution to the International Polar Year
The permafrost monitoring network in the polar regions of the Northern Hemisphere was enhanced during the International Polar Year (IPY), and new information on permafrost thermal state was collected for regions where there was little available. This augmented monitoring network is an important legacy of the IPY, as is the updated baseline of current permafrost […]
Reflections on the Lake Matcharak Paleo-Eskimo dig
By investigating material culture, technological remains from our human past, we can better understand the way people interacted with the environment thousands of years ago. It can give us answers to how people adapted to change, whether it is climactic, technological, or interactions with other cultures. We as a global society are still facing these […]
Notes after our summer field work: Lake Matcharak
When we were working at the Matcharak Lake Denbigh Site in 2009, we noticed on a map that there are other spots around the lake which look like promising spots where people might have lived. So one day instead of excavating, Victoria and I took our boat across the lake and went on a short […]
Matcharak Lake: A seasonal mountain camp
The results of my studies identified four species of fish, dominated by arctic grayling, burbot, lake trout and northern pike, two species of bird, mostly willow ptarmigan, but a few duck bones (species unidentified) were recovered as well. This is important because ducks are migratory species only found in the Brooks Range in warmer months […]
The preservation of archaeological bone
A midden is basically a prehistoric trash dump. After processing animals for consumption, the unusable remains were often discarded in an area of the camp where people were not working and sleeping. Normally in the harsh arctic environment, bones on the surface waste away rather quickly. At Matcharak Lake, however, conditions were just right to […]
Uncovering the frozen remains of a Paleo-Eskimo culture
The Denbigh Flint Complex is the term used to define artifacts left behind by the earliest group of Paleo-Eskimos in Alaska. More broadly, the Denbigh are part of the Arctic Small Tool tradition, the first group of people to colonize arctic America from Alaska to Greenland, after the retreat of the massive ice-sheet that once […]
History in ice, a Paleo-Eskimo excavation
Does watching the archaeologists featured in Paleo-Eskimo videos hard at work– peeling away earth, getting excited over discovering an artifact– summon feelings of jealousy for anyone else? It does for me. The three archaeologists are working to uncover truths 4,000 years old. Situated in Gates of the Arctic National Park, their dig site reveals an […]
