Arctic Climate Monitoring Array—Data Series 812
Every aspect of the Alaskan Arctic environment is expected to be significantly affected over the next few decades, posing a tremendous land management challenge for the U.S. Department of the Interior (DOI). To satisfy DOI's need for accurate environmental information and to improve future climate impact assessments, the U.S. Geological Survey has established an array of climate-monitoring stations on Federal lands in Arctic Alaska as part of the U.S. Department of the Interior/Global Terrestrial Network for Permafrost (DOI/GTN-P) Observing System. This array currently consists of 16 automated stations spanning the National Petroleum Reserve—Alaska and the Arctic National Wildlife Refuge. These data were collected by the U.S. Geological Survey in close collaboration with the Bureau of Land Management and the U.S. Fish and Wildlife Service. This new report is now available on line at: http://pubs.usgs.gov/ds/812/.
How is Climate Change Affecting Migratory Geese in the Arctic?
Every year thousands of black brandt geese migrate to The Arctic Coastal Plain of Alaska where they molt their wing feathers, a process that leaves the birds flightless for three weeks. A recent study by USGS and colleagues from the University of Alaska, Fairbanks and the U.S. Fish and Wildlife Service focuses on how climate change has affected habitat used by the geese. The study found with warming temperatures the flightless geese have shifted from inland lakes to coastal areas where salt marshes provide important habitat offering high quality food and protection from predators for the flightless geese.

USGS Video Commemorates the 1964 Alaskan Earthquake
March 27, 2014 marks the 50th anniversary of the Great Alaskan Earthquake, a magnitude 9.2 earthquake that remains the largest recorded earthquake in US history. Over the last 50 years USGS science has led to a better understanding of mega-thrust earthquakes, subduction zones, the earthquakes they produce, and their associated tsunamis.
