UAF researcher Daniel Mann holds a steppe bison skull from the last ice age that he and fellow researcher Pamela Groves, from the Institute of Arctic Biology, found with the rest of its skeleton in an Arctic riverbank. Although the Arctic's frozen ground preserves bones exceptionally well, Mann said, such complete skeletons are rare. The bison, nicknamed "Bison Bob," lived 40,000 years ago. Mann and Groves recently published a study of ice-age mammal fossil age and abundance in the Proceedings of the National Academy of Sciences. Their results suggest that interconnected habitats can help Arctic mammal species survive environmental changes. Photo by Pamela Groves for the U.S. Bureau of Land Management.

Achievements

Analysis of genetic material from the remains of two ice-age infants discovered in Alaska has revealed connections to two ancient lineages of Native Americans, according to a paper published in the Proceedings of the National Academy of Sciences. UAF archaeologist Ben Potter and University of Utah geneticists Dennis O’Rourke and Justin Tackney deciphered ancient mitochondrial DNA from two infants buried in the Tanana Valley 11,500 years ago. They found that the infants had different mothers and descended from two distinct lineages not previously identified in the North.

Alaska fires release more carbon than trees absorb, according to a new analysis. The research team plugged their data into a computer model developed by co-authors Hélène Genet and A. David McGuire, colleagues at UAF and U.S. Geological Survey. They found that more frequent forest fires have turned Alaska’s Yukon Flats into a net exporter of carbon to the atmosphere. This is worrisome, researchers said, because Arctic and sub-Arctic boreal forests like those of the Yukon Flats contain roughly one-third of the Earth’s terrestrial carbon stores. The research is reported in the journal Nature Climate Change.

International Arctic Research Center researcher Igor Polyakov has been awarded more than $3 million by the National Oceanic and Atmospheric Administration for research on changes in the Arctic Ocean.

Ocean acidification from atmospheric carbon dioxide is expected to rapidly change the Southern Ocean’s chemistry during the next few decades and may threaten marine life, according to a study published in the journal Nature Climate Change. The onset of harmful conditions will be too abrupt and the duration of these events too long for some organisms to adapt. UAF researcher Claudine Hauri and colleagues from the University of Hawaii at Manoa explored how the uptake of anthropogenic carbon dioxide and the resulting ocean acidification will affect the Southern Ocean during the next century.

In Progress

The UAF Chancellor's Search Committee met for the first time in mid-October. The group will work with UA President Jim Johnsen. The search committee is now accepting applications and will select semi-finalists sometime in February and conduct interviews in March. The goal is to have a new UAF chancellor named in April, before the end of the academic term.

Students from the lower 48 states who are interested in attending college in Alaska can get a free flight from Seattle to Fairbanks and back, if they enroll in and pass six credits at UAF this summer. The Summer Sessions & Lifelong Learning program is sponsoring the offer.

What's Next

UAF expects to contract with College Utilities Corp. to provide treated drinking water to the campus by the end of 2015. Until the College Utilities water becomes available to campus, UAF will continue to operate the central carbon filtration system for the campus drinking water. After connecting to College Utilities, UAF will monitor the drinking water quality on campus.

The Arctic Council’s Senior Arctic Officials meeting will take place at UAF March 15-17. The meeting will occur in conjunction with Arctic Science Summit Week 2016. The Arctic Council is a forum to promote collaboration and coordination on Arctic issues among the eight Arctic countries and their indigenous communities. Member countries include Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. The United States assumed the chair of the council in April 2015 for two years.

Associate Professor Denise Thorsen works with electrical engineering graduate student Morgan Johnson on a prototype of the Alaska Research CubeSat.

Students designed and built the cubesat, which was launched into orbit Oct. 8 from Vandenberg Air Force Base in California.

The project was the culmination of an Alaska Space Grant Program project five years in the making. During that time, 36 students worked on the cubesat, with collaboration between the College of Engineering and Mines and the Geophysical Institute.

The Oct. 8 launch put ARC-1 in an elliptical orbit between 310 and 500 miles above Earth. At last check, ground stations had not yet picked up a broadcast signal from the cubesat.

Cameron Gackstetter of Fairbanks claims the $10,000 grand prize in the 2015 Arctic Innovation Competition’s main division at the award ceremony in Wood Center on Oct. 17. Gackstetter won for creating the ThawHead, a portable, 40-pound apparatus that melts ice in a container or work area and then quickly removes the water and any debris. The UAF School of Management coordinates the competition with help from numerous business sponsors. UAF Photo by JR Ancheta.
