NEAR BALLAINE LAKE — Over the blat of engines and hum of tires on nearby Farmers Loop, Mark Spangler hears the chuckles of the animal he is studying. Male wood frogs in a one-acre pond on the campus of the University of Alaska Fairbanks are singing a song of spring. The mating calls of several frogs ring off the eardrum. It's a piercing noise created by air in the inflated cheeks of a creature...

NEAR MILLER CREEK — Crouching amid scratchy spruce branches and surrounded by feet of snow, Amir Allam jabs half-frozen soil with the spikey base of a white cylinder. The seismologist twists the 6-pound seismometer to orient it northward. Then he clicks a cable to a magnetic connection on top. "Starting operation," says a tinny voice that sounds like a woman from London. The words come from a...

This morning, through the west window, I noticed a flash of white. I looked up from breakfast to see a short-tailed weasel popping from a hole in the snowpack. He was sleek and streamlined and snow-white, except for where his tail looked like he dipped it in black paint. Later, a leggy snowshoe hare bounded away, and then paused nervously. Those sightings inspired a visit to my neighbor, who...

A landslide last fall caused a giant wave of the type not seen in Alaska since the storied 1958 event in Lituya Bay. After a period of heavy rains, a mountainside near Tyndall Glacier collapsed into a fiord of Icy Bay on October 17, 2015. The displaced water generated a wave that sheared alders more than 500 feet up on a hillside across from the slide. To put that in perspective, the 2011 tsunami...

About 1,000 years ago, Norse explorer Leif Ericson bumped into the New World at Newfoundland. The old world was filling up, with 300,000 people living in the Roman capital of Constantinople. Up here in Alaska, the ancestors of today's coastal Natives were quietly having one of the more successful runs in human history. The Thule people of Alaska's west and north coasts lived a good life for...

Ships with no humans aboard have long ridden the seas, often floating with supernatural stories of being piloted by dead crew members or becoming visible to sailors and then vanishing. Alaska has its own ghost ship. Workers for the Hudson Bay Company abandoned the S.S. Baychimo just offshore of Wainwright 85 years ago. Sea ice trapped the 230-foot cargo steamship during an early winter in October...

For half the year, Alaska's big rivers provide a somewhat flat surface, allowing travel by snowmachine, dog team, ski, bike, snowshoe and foot. For a few weeks during their spring transition to liquid water, those useful ribbons of ice become a threat to river communities. Massive ice-jam floods happen every few years on Alaska rivers. Some of them are large enough to cause damage more than $80...

Last Friday, an email popped up in all the mailboxes of people with the Geophysical Institute: Someone saw what might have been a wolf on the trails north of the UAF campus. "Please be cautious if skiing in the area." A few people responded, saying they had seen one or two coyotes roaming the 1,000-plus acres of trails and frozen wetlands just north of campus buildings and roads. UAF ski trail...

For a town of its size (4,300 people), Barrow receives more visits by scientists than anyplace in America. The northernmost community in the U.S. has hosted researchers since Army Lieutenant P. Henry Ray built a polar observatory there in 1882. This different-than-anywhere-else place with fewer people than a one-stoplight town in Texas has attracted scientists from all over the globe. Why?...

In anticipation of an arctic science conference happening next month in Fairbanks, an editor asked me to write a column on climate change in the north. I told her climate stability would be the bigger story, since basswood trees used to grow in Fairbanks and redwoods once dropped their cones into the Porcupine River. Climate is always changing. But we have gotten much better at measuring those...
