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...

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...

Along Alaska's southern coast, harbor seals use icebergs from tidewater glaciers as platforms to give birth, nurse, molt and avoid predators. As these glaciers melt and thin, some may retreat onto land and no longer calve into the ocean. Researchers from the University of Alaska Fairbanks Geophysical Institute and the National Park Service have successfully tested a method to measure how much...

Around 65 million years ago, a massive asteroid crashed into the Gulf of Mexico. The impact and subsequent effects wiped out about 75 percent of all life on Earth, including most of the dinosaurs. Scientists studying the resulting Chicxulub crater are learning how large asteroid impacts deform rocks in a way that may produce habitat advantageous to early life forms. In April and May 2016, an...

Staff at the University of Alaska Fairbanks helped with a successful test of a high-altitude glider to help evaluate how advanced surveillance technologies could be used to track winged vehicles returning from space. During the test this fall in Oregon, researchers at UAF's Alaska Center for Unmanned Aircraft Systems Integration supported the drop of a small unmanned glider from a high-altitude...

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...

On a recent river trip down the Porcupine River, my friend Garrett Jones and I nosed into a few townsites we saw on the map. Old Camp, Canyon Village and Shuman House were all silent places with no people but the same unique regional touch: Decorative stamped-metal ceiling panels tacked up as outhouse walls.   During our 200-mile trip down the Porcupine's length in Alaska, we saw no...

YUKON FLATS — Out here, in a smooth plain stretching over Alaska’s wrinkled face, water and tree and mud dissolve to fuzz at each horizon. No hills or bumps. An ocean of sky. An observer once said Yukon Flats looks like a place where God forgot to put something.   Garrett Jones and I are camped on a giant island not far from the Yukon River map feature labeled "Halfway Whirlpool."...

Sometimes, a great idea arrives ahead of its time. A person squints at a raw landscape, thinks about it in his bunk on a heaving ship, dreams of it. He scribbles a diagram. He remains quiet years later as others rediscover the same thing.   Such was the case of a rugged geologist who island-hopped in the Aleutians following World War II. Thinking about the age of rocks he found, the...
