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 […]
Nenana’s airport will be the site of a new 4,800-square-foot hangar for the Alaska Center for Unmanned Aircraft Systems Integration. The hangar will serve as a base for drone cargo test flights between Fairbanks and the small city 54 miles to the southwest. The University of Alaska Board of Regents approved $3.3 million for the […]
Specialized portable radar could serve as an early warning system to reduce risk for humans working on shorefast sea ice, according to a recently published study. The researchers suggest that use of portable interferometric radar can quickly reveal small changes that could indicate imminent movement or detachment of the ice, which is important as climate […]
