GI scientists help fuel delivery to Nome: Provide crucial information on ice conditions
Andy Mahoney, an assistant research professor with the Sea Ice Group at the Geophysical Institute, is helping to determine ice conditions near Nome, Alaska so a fuel tanker can deliver much-needed fuel to the northwest community.

Hajo Eicken
Dr. Eicken's research includes studies of the growth, evolution and properties of sea ice. Hajo is particularly interested in determining how microscopic and macroscopic properties affect larger-scale sea-ice processes and its role in the climate system. He also investigates different uses of sea ice by indigenous communities, the private sector and the public at large and aims to provide data and information that can help decision-makers adapt to a changing Arctic.

The greatest story of man and permafrost
Engineer Elden Johnson, seen here giving a pipeline talk in 2008.

In 1973, Elden Johnson was a young engineer with a job working on one of the most ambitious and uncertain projects in the world — an 800-mile steel pipeline that carried warm oil over frozen ground. Thirty-five years later, Johnson looked back at what he called “the greatest story ever told of man’s interaction with permafrost.”

Alaska Science Forum: Once again, news of the world from San Francisco
By Ned Rozell
SAN FRANCISCO — For the thirteenth straight year, I’m happy to be spending one week of December here, at the Fall Meeting of the American Geophysical Union, where more than 15,000 scientists gather for a week to discuss the latest news of the world.
Here are a few items from the first two days:
