Alaska Science Forum: Bison Bob a big discovery on the North Slope
As she scraped cold dirt from the remains of an extinct bison, Pam Groves wrinkled her nose at a rotten-egg smell wafting from gristle that still clung to the animal’s bones. She lifted her head to scan the horizon, wary of bears that might be attracted to the flesh of a creature that gasped its last breath 40,000 years ago. In the type of discovery they have dreamed about for years, Groves and Dan Mann, both rese...

Alaska Science Forum: White River ash made its way across the globe
The White River Ash, blasted from giant eruptions somewhere in today’s Wrangell-St. Elias Mountains, drifted as far away as Ireland and Germany, said experts who attended the December 2012 Fall Meeting of the American Geophysical Union, held in San Francisco. Ash from the White River eruptions, possibly from 15,638-foot Mount Churchill or at least close to it, left an easy-to-see mark on eastern Alaska and northwe...

Alaska Science Forum: Bowheads rise, Barrow sinks, fire scars the tundra
From my notebook, here’s more northern news presented at the Fall Meeting of the American Geophysical Union, a five-day gathering of more than 20,000 scientists held in early December 2012 at the Moscone Center in San Francisco: Bowhead whales counted from a sea-ice perch north of Barrow are “doing beautifully,” according to Craig George with the North Slope Borough. Since 1978, George has counted bowhead whales f...

Alaska Science Forum: Alaska forests in transition
In almost every patch of boreal forest in Interior Alaska that Glenn Juday has studied since the 1980s, at least one quarter of the aspen, white spruce and birch trees are dead. “These are mature forest stands that were established 120 to 200 years ago,” said Juday, a professor of forest ecology at the University of Alaska Fairbanks’ School of Natural Resources and Agricultural Sciences. “Big holes have appeared i...

Alaska Science Forum: Climate change and the people of the Mesa
Alaska was once the setting for an environmental shift so dramatic it forced people to evacuate the entire North Slope, according to Michael Kunz, an archaeologist with the Bureau of Land Management. About 10,000 years ago, a group of hunting people lived on the North Slope, the swath of mostly treeless tundra that extends north from the Brooks Range to the sea. These people, known as Paleoindians, used a chunky r...

Alaska Science Forum: Dramatic report card for the Arctic in 2012
SAN FRANCISCO — Northern sea ice is at its lowest summer coverage since we’ve been able to see it from satellites. Greenland experienced its warmest summer in 170 years. Eight of 10 permafrost-monitoring sites in northern Alaska recorded their highest temperatures; the other two tied record highs. 2012 was a year of “astounding” change for much of the planet north of the Arctic Circle, said four experts at a press...

Alaska Science Forum: Forty years of change on top of the world
SAN FRANCISCO — From a lecture hall within a land of warm breezes and flowering December plants comes a story of a creature 2,600 miles north, where the sun will not rise for another 50 days. At the 2012 Fall Meeting of the American Geophysical Union, biologist George Divoky had 15 minutes to present his lifetime of work with a bird that adapted to year-round life in the Arctic during the last ice age. Divoky led ...

Alaska Science Forum: Yakutat time, correcting some errors, big meeting in San Francisco
A few people contacted me after a column I wrote on time zones a while back. Flip Todd of Anchorage called to say Yakutat clocks displayed a different time than those anywhere else in Alaska prior to 1983. Back then, before Alaska went to the current two-time-zone system, Yakutat followed Yukon time, one hour removed from both Juneau and Anchorage. Flip also corrected my misspelling, in a later column, of the Tako...

Alaska Science Forum: Goodbye to a giant of glacier research
High-school dropout Austin Post’s career began in the 1950s, when colleagues made up the title “Senior Meteorologist” to include him in a funding proposal. Post later recalled with humor that he misspelled both of those words on his application. Despite objections from the secretary that processed his paperwork, Post then embarked on a decades-long adventure of capturing images of North America’s glaciers from the...

Alaska Science Forum: Ancient skeletons of McGrath raise questions
The room smelled of a smoked moosehide covering a table that held birch-bark baskets and a white box rimmed with beadwork flowers. Inside the box were the smooth bones of an adult man, a teenager and a child dug up within sight of the McGrath School. The discovery, recently announced in the Morris Thompson Cultural and Visitor’s Center in Fairbanks, is unique because bones don’t often last for hundreds of years wh...
