Alaska Science Forum: Alaska earthworms little known
Under its own power, an earthworm gains about 30 feet of new territory each year. But that does not help explain how worms got to Alaska. “It’s almost geologically slow,” Matt Bowser, said of the earthworm’s locomotion. Bowser, Alaska’s closest thing to an expert on earthworms, is an entomologist with the Kenai National Wildlife Refuge. He has taken an interest in worms that exist in surprising numbers in southern...

Alaska Science Forum: Citizen science meets the aurora
A scientist named Victor Hessler once made an aurora detector by driving two metal rods in the ground a few hundred feet apart and stringing a wire between them. When voltage changed along the wire, a bell rang. Hessler then pulled on his boots and went outside to take black-and-white aurora photos. During the recent St. Patrick's Day geomagnetic storm, people all over North America became aurora detectors. They u...

Alaska Science Forum: Catching a lake as it became land
If a lake drains on top of the world, will anyone hear it? Ben Jones and Chris Arp did. The Anchorage- and Fairbanks-based scientists placed sensors in a bathtub-shaped lake on Alaska's northern coast a few years ago. From what they can tell, the lake topped its rim and eroded/thawed a channel to the Beaufort Sea on July 5, 2014. With a flow greater than some northern rivers, the lake's water spilled into the ocea...

Alaska Science Forum: Short, chubby and neurotic is good combination in cold
This message came from the grandfather of 5-year old Ben, who lives near Inverness, Scotland: Even in winter he will rapidly strip off and often plays in a sleeveless vest while others still have a shirt and woolly jumper on. He appears to be always warm. He goes to an excellent school but complains that the rule in winter is that they must wear their coats outside. He finds even a light coat uncomfortable in norm...

Alaska Science Forum: They don’t make ice mounds like they used to
On a February day long ago, a family living in a sod hut near the Arctic Ocean saw blocks of sea ice bulldozing their way onto shore. Winds shoved more ice until the mass towered above them and started dripping water through a ventilation hole. The father urged his family outside just before a slab fell on the hut and crushed him. An ivu — the Inupiat word for mounds of ice that sometimes plow onto land, powered b...

Alaska Science Forum: A yearly flood into the Gulf of Alaska
Satellite data has confirmed that the amount of freshwater released into the Gulf of Alaska from streams and rivers in Alaska and northern Canada is about 1.5 times what the Mississippi River dumps into the Gulf of Mexico each year. That astounding flow of water is from rainfalls that soak Southeast Alaska and the south side of the Alaska Range. The other half comes from the melting of snow and ice from glaciers. ...

Alaska Science Forum: Rafts of birds overwintering in the Bering Sea
Like flecks of pepper on chowder, all of the spectacled eiders on the planet are now gathered amid sea ice and steaming open leads in the Bering Sea. "It's a mass of life in this desolate area," said Matt Sexson, who once rode an icebreaker to see the winter gathering south of St. Lawrence Island. Sexson, a biologist with the USGS Science Center in Anchorage, just handed in a draft of his Ph.D. chapter on the crea...

Alaska Science Forum: The continued mystery of the Denali Gap
North America's highest mountain should be a volcano. Denali sits about 60 miles above where the Pacific Plate grinds beneath the North American plate, as do Iliamna, Redoubt and Augustine. If you draw a line from the Aleutians to volcanic features in interior Alaska, the curve goes over Denali's summit. Like its neighbors in the Alaska Range, the big mountain shows no signs of having erupted. But seismologists re...

Alaska Science Forum: Digging up Augustine's top-heavy legacy
Augustine Volcano sits alone, a 4,000-foot pyramid on its own island in Cook Inlet. Like many volcanoes, it has a tendency to become top heavy. When gravity acts on Augustine's oversteepened dome, rockslides spill into the ocean. A scientist recently found new evidence for an Augustine-generated tsunami from a time when Egyptian pharaohs built their own pyramids. Zebulon Maharrey's record of a tsunami deposit from...

Tidal stresses and giant earthquakes
A scientist once noticed a connection between the stress that tides inflict on the planet and the number of small earthquakes that happen in some areas when that pressure is greatest. She saw a pattern to these earthquakes leading up to great tsunamis. A graduate student is now looking for a similar signal in Alaska. Yen Joe Tan of Columbia University is combing through a database of offshore Alaska earthquakes to...
