The monetary impact of changes in snowfall due to climate change is likely in the trillions of dollars. Professor Matthew Sturm, with the University of Alaska Fairbanks Geophysical Institute, reported in a recent paper for the American Geophysical Union that the costs of snowfall changes are “measured in trillions, not billions, of dollars.” Sturm collaborated on the invited paper with Michael...

Glaciers and ice sheets move in unique and sometimes surprising patterns, as evidenced by a new capability that uses satellite images to map the speed of flowing ice in Greenland, Antarctica and mountain ranges around the world. With imagery and data from Landsat 8, a joint mission of NASA and the U.S. Geological Survey, scientists are providing a near-real-time view of every large glacier and...

Improved satellite technology is allowing researchers to more accurately measure how glacier ice could affect global sea levels. A team of international scientists, including Mark Fahnestock of the University of Alaska Fairbanks Geophysical Institute, have studied thousands of satellite images taken since 2013 to gauge how rapidly glacier ice is being dumped into the ocean. The analysis, using...

Pine Island Glacier — about the size of Florida and one of the largest ice streams in Antarctica — has been thinning and retreating at an alarming rate since 1992, when satellite images first began to document the change. New evidence suggests that the thinning and retreat of Pine Island Glacier was underway as early as the 1940s, an international team reported Nov. 23 in the journal Nature. Ice...

CONTACT: Marmian Grimes, 907-474-7902, mlgrimes@alaska.edu A new mapping project has identified regions worldwide that are most susceptible to dramatic permafrost thaw formations, known as thermokarst, and the resulting release of greenhouse gases. University of Alaska Fairbanks researchers David McGuire and Vladimir Romanovsky were part of the project, which was led by University of Alberta...

By Ned Rozell TOOLIK FIELD STATION -- Despite a wind that makes today's minus 14 degrees Fahrenheit feel like minus 39, a worker at this research camp in blue-white hills north of the Brooks Range has proclaimed this the first day of summer. Today, the population of Toolik Field Station increases from nine -- five people running the camp, three scientists and me -- to 16. Seven support...

By Ned Rozell Cold water the color of iced tea wets the boots of Chris Arp as he yanks a power auger from the hole he just drilled in this quiet lake, a few miles from his office at the University of Alaska Fairbanks. A whiff of sulfur -- a sign there's not much oxygen in this pond born when ancient frozen ground thawed -- wafts upward as Ben Gaglioti clears slush from the hole with a...

Satellite data for the Arctic has shown that the amount of vegetation has increased or greened over the last three decades. A group of multidisciplinary scientists have worked together for the last decade to identify the causes of these changes and highlights of this research will be presented as the fifth installment in the 2014 Science for Alaska Lecture Series on Tuesday, February 18 at 7 p.m...

By Ned Rozell How big is the American Geophysical Union Fall Meeting held in San Francisco every December? So big it’s like everyone from Barrow attending on Monday. The residents of Soldotna get Tuesday, Valdez Wednesday, Nome Thursday and Kotzebue Friday. More than 21,000 scientists walk through the Moscone Center during the week, along with others, like me, who are curious about what...

Girls on Ice is a unique, free, wilderness science education program for high school girls. Each year, a team of nine teenage girls and three instructors spend eleven days exploring and learning about mountain glaciers and alpine landscapes through scientific field studies with professional glaciologists and mountaineers. Applications for the summer 2014 program can be submitted now through...
