On the ground in Barrow, Alaska

Susan HubbardSusan Hubbard (Photo courtesy the researchers)Geophysicist Susan Hubbard (Ph.D.’98 CEE) leads a research team from the Lawrence Berkeley National Laboratory in Barrow, Alaska—the northernmost city in North America—as part of the 10-year Next-Generation Ecosystem Experiment (NGEE). The NGEE is a collaboration between scientists and engineers who are trying to better understand changes in the Arctic tundra, so that they can improve climate predictions. Hubbard studies the structure beneath the subsurface to detect thawing that could lead to the release of greenhouse gasses from organic matter trapped below ground. Despite below-freezing temperatures and the threat of polar bears, Hubbard sends this report back from the field: “The data have been gorgeous. There is so much good energy. So it’s very, very fun.”
