A group of researchers have found that the ocean floor around Bering Strait still seems to be capturing billions of bits of carbon that might otherwise lead to an even warmer planet.

Will Harrison, who knew the world’s bumpy plains of ice as well as his old neighborhood in Saint John, New Brunswick, has died. He was 84. From his arrival at the Geophysical Institute at the University of Alaska Fairbanks in January 1972, the Canada-born Harrison mapped out and executed studies of glaciers from Antarctica to Greenland. He and his charges measured and reported great changes before they became obvious.

Within their bulbous bodies, Steller sea lions of the western Aleutian Islands seem to carry more mercury than sea lions closer to mainland Alaska. By looking at tiny bits of fish and squid, a graduate student is trying to find out where that mercury is coming from.

They are savvy to disguises, but can get spooked by novel costumes. Trick or treat?

Fee, who is also a researcher with the Alaska Volcano Observatory, finds infrasound useful for capturing the explosive roar of volcanoes. Scientists have also detected the aurora borealis stirring the thin air above us, and the air disturbed by far-off mine explosions. And, it turns out, infrasound is also a good tool for measuring the path of space rocks screaming through the 30-mile shell of gases surrounding our planet.

A 9-year-old Carl Tape — now a seismologist at UAF’s Geophysical Institute — poses beside a thermometer registering 50 below zero Fahrenheit during a Fairbanks cold snap in January 1989.
The new model, whose color scheme is admittedly quite shocking (think Pepto-Bismol bottle), is shown… The interesting fault is at the center of the image. The fault is traced in black in the lower image, with arrows indicating movement sense.

A large sandstone blockslide in Highland County, Virginia presents an unusual appearance in LiDAR hillshade imagery–it appears to have moved sideways across a slope instead of directly down the slope.

On the first day of October, a little girl pulls on her rubber boots and rushes outside into crisp fall air. She knows the days are getting shorter, but she doesn’t realize Alaska is a week past the autumnal equinox. On the equinox, the sun appears to sit over Earth’s equator, causing days and nights to each last about 12 hours everywhere in the world. It is time for Alaskans to start paying the bill for all that summer daylight.

That 85-year-old scientist — David Klein — is now 93. He lives in Fairbanks. He was my neighbor when he last journeyed to St. Matthew Island. I went on that trip with him and a dozen others. Klein was my cheery tent-mate.
