SAN FRANCISCO — On rare winter mornings here, a skim of ice forms on sidewalk puddles. But water's solid form is mostly an abstraction in this land of blooming flowers and the hummingbirds that visit them. Except for the week of the fall meeting of the American Geophysical Union.   Dozens of the 22,000 scientists gathering here for the week are talking about ice, mostly about how much of...

A lynx that roamed more than 200 miles from Kluane Lake in the Yukon Territory to near Chitina is still being tracked across the Alaska landscape, thanks to a curious couple living off the Edgerton Highway.   Ralph and Linda Lohse first met the animal Canada researchers call Max on an October night.   "My wife saw a lynx out there, sitting next to the chicken coop like a lion,...

Joanna Young does not seem to fear change very much. She first came to Fairbanks from Egypt, where her parents were teaching English and running a school. Raised in Toronto, she knew what cold was. But this was January 2010, a colder-than-average month. The temperature bottomed out at minus 41 F as she arrived.   "It was a good climate shock and a good culture shock," said Young, 32, who...

After Hurricane Ike in 2008 shoved six feet of water into downtown Galveston, Texas, people there had the attention of all America. But two days later, lawyers for Lehman Brothers filed the largest bankruptcy in America's history. The Federal Reserve bailed out insurance giant A.I.C. with an $85 billion payment, and Americans were paying attention to other things.   That was too bad for...

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...

A NASA-sponsored field experiment is providing new insight about the levels of methane escaping from Arctic lakes. Using satellite imagery, University of Alaska Fairbanks researchers have been measuring bubbles beneath the ice of lakes throughout Alaska. By analyzing data from numerous sites, the project aims to estimate the amount of methane being released to the atmosphere through thermokarst...

The University of Alaska Fairbanks will offer a new online course this spring geared to help educators teach about earthquake science. The one-credit professional development course will provide teachers with the knowledge, tools and resources to teach earthquake topics to a wide range of students, from K-12 to community college levels. The course will guide teachers through hands-on...

This week, GI and UAF scientists are with colleagues from around the world at one of the globe’s largest scientific conferences, the American Geophysical Union’s 2016 fall meeting. Researchers, both faculty and students, are presenting their work and meeting with collaborators and funding agencies. UAF PIO Jeff Richardson is blogging about GI and other UAF researchers’ presentations and other...

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...
