GECSC Geologist Lesleigh Anderson is quoted in the LiveScience article Despite Warming, Ground Refreezes at Alaska's Shrinking Lakes. This story describes a recent study led by Martin Briggs and other USGS scientists that reports on new permafrost forming around a shrinking lake in Alaska's interior. Lesleigh explains how her 2013 study of the lake's lower water levels can be attributed to less precipitation and more evaporation that may be a reflection of normal Pacific climate cycles that affect the region. Together the two studies provide new insights into the dynamics between climate, surface water and permafrost in Alaska.

Ecosystem services are the benefits that nature provides to human well-being—from clean air and water, protection from natural disasters, fisheries, crop pollination and control of pests and disease, and outdoor places for recreation, solitude, and renewal. The Ecosystem Services Assessment and Valuation (ESAV) project's new website gives an overview of research underway by the ESAV team, such as the study of spatial subsidies for migratory species, resource management on public lands, and the development and use of ecosystem services tools.

The GECSC NLCD team (Cartographer Catherine Costello, Cartographer Rick Poss, and Physical Scientist Lori Baer) produced about one third of the dataset found in the newly released 2011 edition of the National Land Cover Database (NLCD). The purpose of the database, a product of the Multi-Resolution Land Characteristics Consortium, is to provide complete, current, consistent, and public domain information on the Nation's land cover. The NLCD team is currently working on updating the database to include Alaska, which is scheduled to be published in December 2014.
