Evidence indicates a thick ice sheet, not annual sea ice and icebergs, covered the Arctic Ocean at some point during the last 140,000 years. Now, University of Alaska Fairbanks scientists will be looking for more geologic proof of the ice sheet’s existence, sources, behavior and extent. UAF Geophysical Institute scientists will focus on the Beaufort and […]
A small piece of Pacific Ocean floor, brought up 10 years ago by a Chinese research vessel from a depth of 16,500 feet and 2,700 miles from the San Francisco coast, has a large story to tell. Researchers say a one-fifth-inch slice of that marine ferromanganese nodule, which measured 1 by 1.4 inches before it […]
Under its own power, an earthworm gains about 30 feet of new territory each year.

Bowser, Alaska’s closest thing to an expert on earthworms, is an entomologist with the Kenai National Wildlife Refuge. […]
Sealaska Heritage Institute will offer its last noon lecture of the year on Tuesday. Forest Geologist Jim Baichtal will talk about the search for early habitation sites on ancient shorelines in Southeast Alaska. He’ll discuss a new model that has helped scientists discover more than 70 ancient sites with archaeological materials that are rich in […]
