Pilgrim Hot Springs thermal

Measuring and modeling geothermal resources at Pilgrim Hot Springs

There’s a place where the perennially frozen ground of the Alaskan tundra is interrupted by 2 square miles [~ 5 km² ] of thawed soil. There, cottonwoods and thick brush grow among lazily meandering waterways. The Pilgrim Hot Springs are a pleasant symptom of the geothermal heat which warms the earth deep beneath Alaska’s Seward […]

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 […]

Antarctic pancake ice

Against the odds Antarctic sea ice is growing– here’s why

“On any given day, sea ice cover in the oceans of the polar regions is about the size of the U.S.,” Thorsten Markus reminds us. He’s a research scientist at NASA’s Goddard Space Flight Center. “Far-flung locations like the Arctic and Antarctic actually impact our temperature and climate where we live and work on a […]

Orbital dynamics and climate

Laura Nielsen for Frontier Scientists – Cyclical changes in the way the Earth circumnavigates the Sun can influence Earth’s climate. Last week, we looked at Milankovitch’s assessments of orbital dynamics, including: orbital eccentricity, Earth’s tilt or obliquity, and the precession or change in orientation of the Earth’s axis of rotation which determines what direction each […]

Burned Alaska may cause more burned Alaska

Ned Rozell for UAFGI – The blackened scars that Alaska fires leave on the landscape may result in more lightning, more rain in some areas just downwind of the scars, and less rain farther away, according to two scientists. Nicole Mölders and Gerhard Kramm, both of the Geophysical Institute at the University of Alaska Fairbanks, […]

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 […]

Know your land: Alaska maps

Laura Nielsen for Frontier Scientists – Over eight thousand historical maps of Alaska are now available to the public through the United States Geological Survey’s Historical Topographic Map Collection. The collection includes maps of Alaska crafted as long ago as 1899, maps created to commemorate Alaska’s induction into statehood in January 1959, and more. Records of […]

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 […]
