Abstract:
Alaska Science Forum: Explorer's magnetic measurements ring true
By nrozell [at] gi [dot] alaska [dot] edu (Ned Rozell)
More than a century ago, Roald Amundsen and his crew were the first to sail through the Northwest Passage, along the way leaving footprints in Eagle, Nome, and Sitka. Pioneering that storied route was a dream of Amundsen’s since his boyhood in Norway, but he also performed enduring science on the three-year voyage of the Gjøa.

Fairbanks, Alaska— University of Alaska Fairbanks professor emeritus Davis “Dave” Sentman has been elected to the 2012 class of fellows for the American Geophysical Union.
Alaska Science Forum: When NASA visited Venetie
Bynrozell [at] gi [dot] alaska [dot] edu ( Ned Rozell)
VENETIE — The cozy log structure smells of coffee, gasoline, and spruce logs burning in a stove made from a 55-gallon drum. Inside the building that serves as the Village Council headquarters for Venetie, Josh Bundick explains a new policy that rewards villagers who find spent rocket parts launched from north of Fairbanks.
