Ice and fire and permafrost

May 20 2015, 9pm in Alaska, tune in to KAKM Science Wednesdays, Alaska Public Media, for Frontier Scientists’ CHANGING PERMAFROST. Under the tundra thawing Permafrost forms thermokarst features, causing sinkholes and landslides. Shifting climate conditions release greenhouse gases locked beneath the tundra in previously frozen ground. The episode features University of Alaska Fairbanks Geophysical Institute […]

HAARP transmitters

What is (and imminently “was”) HAARP?

Googling HAARP used to be useless, which was astonishing for someone of my generation. Even now, most results outline the conspiracy theories behind the $300,000,0000 facility in rural Alaska. Occasionally my good friend and coworker, Dr. Chris Fallen, spoke about HAARP and his experiments there.

Predicting the effect of anomalous sea ice loss and increasing sea surface temperatures on global storm systems

Azara Mohammadi – To become a PhD candidate at the University of Alaska Fairbanks, Soumik Basu moved from his home in Kolkata, India to a region infamous for its “below zero” weather: Interior Alaska. Basu left warm weather and his family (not to mention his mother’s cooking) because “The climate is changing, so I wanted […]

Modeling shifting oceanscapes; a collective pursuit

Azara Mohammadi for Frontier Scientists – In 1996, Dr. Kate Hedstrom travelled to Norway to “Sit on Paul Budgell’s steps,” as she says. She went there to get a piece of code recently improved by Paul Budgell. “He promised his model and I went to Norway to get it!” says Kate. Hedstrom is an Oceanographic […]

A continent of ice on the wane

Ned Rozell for UAFGI – Despite taking up as much space as Australia, the blue-white puzzle of ice floating on the Arctic Ocean is an abstraction to the billions who have never seen it. But continued shrinkage of sea ice is changing life for many living things. A few Alaska scientists added their observations to […]

Redoubt volcano plume

Mount Redoubt sounds off

Volcanoes are an awe-inspiring and hazardous part of our planet. And now, they’re being made to sing. Scientists are turning seismic data into audio data in order to grasp just what’s going on deep in the Earth’s crust, and better forecast future explosive eruptions.

VIIRS as an Arctic Nightlight

Liz O’Connell for Frontier Scientists – During winter in the Arctic it’s “night” almost all the time, but thanks to the new Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) we no longer have to be in the dark about what’s going on with the weather.  Here is a VIIRS/DNB image of the Alaska […]

New UAF program draws young artists into science

Marie Thoms for UAF Cornerstone – Artists and scientists often share a common goal: making the invisible visible. Yet artistically talented students, especially girls, often shy away from scientific careers. A new four-year program led by the University of Alaska Fairbanks blends the art, biology and physics of color into a series of summer academies, […]

Guillemots, and the Edge of the Ice

Laura Nielsen for Frontier Scientists The Bering Sea region hosts over 90% of seabirds breeding in the continental United States. Most of those birds are hardy migrators, breeding on Alaska’s coast in the warm season and then departing south, chased away by the cold weather. One group which remains is Guillemots, a type of seabird […]

ARSC Fish: CRAY Supercomputer Enables Scientific Discovery

Liz O’Connell for Frontier Scientists – Fairbanks, Alaska, November 6, 2012 – The Arctic Region Supercomputing Center at the University of Alaska Fairbanks has a new CRAY Supercomputer Called FISH. As ARSC transitions from a centralized machine to a strategically upgradeable hybrid system, they advance scientific discovery. It is a large scale upgrade to benefit research. Scientists who use […]

Scientists identify likely origins of vertebrate air breathing

Marie Thoms for UAF Cornerstone – University of Alaska Fairbanks scientists have identified what they think is the ancestral trait that allowed for the evolution of air breathing in vertebrates. They presented their research at the 42nd annual meeting of the Society for Neuroscience Oct. 17 in New Orleans. “To breathe air with a lung, […]

A Portal to Toolik Field Station

Laura Nielsen for FrontierScientists We know that the Arctic holds unique climate conditions and a complex carbon balance. Tundra fires and thawing permafrost release carbon dioxide into the atmosphere, while unique ocean currents and cold waters prompt higher levels of ocean acidification. Methane emerges from sea and soil. The Arctic sea ice cover shrinks to increasingly startling extents. Plant life […]

Ocean Acidification

  Laura Nielsen for Frontier Scientists Will ocean acidification spell a watery grave for vital parts of marine ecosystems? Marine ecologist Jane Lubchenco, head of the National Oceanic and Atmospheric Administration, named ocean acidification global warming’s “equally evil twin.” * Burning fossil fuels — coal, oil, natural gas — cutting down forests and other post-industrial […]

Cray Inc. provides “Fish” for Arctic Region Supercomputing Center (ARSC).

Liz O’Connell for Frontier Scientists – Fairbanks, Alaska, October 2, 2012 – “As Alaska’s Research University UAF (University of Alaska Fairbanks) must continue to provide the best tools, ARSC is one of the most important tools available,” said Brian Rogers, Chancellor at the University of Alaska Fairbanks. And the Arctic Region Supercomputing Center’s new tool […]

Glaciologists help with recovery of human remains

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 […]

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 — […]

Making sea ice 300 miles from the ocean

Ned Rozell for UAFGI – Marc Mueller-Stoffels unscrews the top of a glass jar and invites a visitor to smell the powder inside. A sniff evokes the image of kayaking Prince William Sound or walking a beach in Southeast. “We call it ‘Instant Ocean,’” he says, returning the lid to the jar. Mueller-Stoffels, a doctoral […]

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 […]

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 […]

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, […]
