Alaska Science Forum: Tiny barbarians at the gate
Mosquitoes and black flies, now stirring after a long winter, have probably helped assure that most of Alaska remains unpopulated, says an expert on those creatures. “I’ve spent a lot of time in the far north — in Canada, Siberia, and Alaska,” said Peter Adler, a professor of entomology at Clemson University. “You can go down rivers for a month or two at a time and see no humans. Why is that? What’s keeping them o...

Alaska Science Forum: Looking back in time at the world’s oceans: 
old satellite imagery provides new baseline data
A time capsule of satellite imagery of the earth will become available to scientists this month. On June 28, digital imagery from more than three decades ago will be released by the Alaska Satellite Facility at the University of Alaska Fairbanks Geophysical Institute, NASA’s processor and distributor for this type of data. The images reveal an unprecedented view of sea ice, waves, forests, glaciers and more. “It w...

Alaska Science Forum: Mammoths and microblades: digging up ancient culture in Interior Alaska
On a small hill surrounded by boggy muskeg in the Tanana River Valley, prehistoric skin scrapers made of schist, polished slate tools and glass beads were uncovered in the last week. Based on the design of the tools and the way the animals were butchered, it appears to be an Athabascan campsite from the turn of the 20th century. “These are very typical Athabascan tools. But you usually think of polished stone tool...

Alaska Science Forum: Measuring glacier wastage
Every summer, Alaska’s glaciers melt and send vast quantities of water gushing through silty gray rivers, past towns and villages and finally into the sea. Some glaciers calve directly into the ocean, instantly losing car-sized chunks of ice and wowing boats full of tourists. The world’s melting glaciers are boosting ocean levels 0.71 millimeters a year, accounting for roughly one-third of total sea level rise, ac...

Alaska Science Forum: When volcanoes awaken
“This morning the seismic tremor was down just a little bit from yesterday. We’re hoping it calms down before too long, but it might last for awhile.” Jeffrey Freymueller was on the phone last week with the electric utility in Cold Bay, a community about 40 miles from the Pavlof Volcano, which had been erupting for more than a week. The utility was wondering how much ash fall to expect and whether it would need to...

Alaska Science Forum: The art of ice coring
The trick to getting a good ice core is to drill straight down into the sea ice, continually clear the slush gurgling up from the ocean, correctly reassemble the core fragments on the tray, take its temperature every couple of inches before it melts or cools, and saw it into hockey-puck-sized chunks without dropping them in the snow. And, of course, not drop the heavy drill blade on your foot or frostbite your fin...

Alaska Science Forum: Barrow — Spring is in the air and in the ice
On the 5-mile snowmachine ride to Point Barrow, we saw several fresh polar bear tracks the size of dinner plates, a pile of whalebones from last year, and a 3-foot-wide crack in the sea ice that could swallow a sled. The crack was created when an ice floe in the open water crashed into shore-fast ice. It was masked by a snowdrift, and our guide Brower Frantz nearly fell into it. Frantz’s job is to spot and avoid h...

Alaska Science Forum: Predicting the future: where do climate projections come from? or Using climate data to predict snow in Alaska
In Alaska, our lives revolve around the weather. When it comes to predicting conditions like temperature, snow and rain, the best glimpse into the future comes from climate models. But standard climate models are very broad — looking at how global climate will be affected by things like escalating carbon dioxide emissions. In a land of permafrost, icefields, massive mountain ranges and rainforest, a more nuanced p...

Billions of cicadas will take over the East Coast
WASHINGTON (AP) — Any day now, billions of cicadas with bulging red eyes will crawl out of the earth after 17 years underground and overrun the East Coast. The insects will arrive in such numbers that people from North Carolina to Connecticut will be outnumbered roughly 600-to-1. Maybe more. Scientists even have a horror-movie name for the infestation: Brood II. But as ominous as that sounds, the insects are harml...

Alaska Science Forum: Cook Inlet earthquake
Red and blue waves triggered by a magnitude 4.6 earthquake rippled outward from the Anchorage area and fizzled out after 45 seconds. Except in Cook Inlet basin, where the waves were trapped for another half-minute, bouncing back and forth, up and down, within the 7.5-kilometer-thick sedimentary basin. “It’s like throwing a rock in the pond. Except water is a homogeneous material. In the solid earth you have basins...
