Map Store @ USGS Closing Fall 2014


Map Store logo The Map Store @ USGS on the Alaska Pacific University in Anchorage will be closing. The store will remain open through October 31, 2014. A joint USGS and Alaska Geographic news release is available with additional information on the closure and options for obtaining maps in the future. Please visit the Accessing Alaska USGS Topographic Maps link available on the Maps, Products & Publications page for additional information on downloading or purchasing USGS topographic maps of Alaska. Or, visit the USGS Store at store.usgs.gov.

Through the Eyes of a Polar Bear - First Ever Video from a Free Ranging Polar Bear on Arctic Sea Ice

YouTube video Through the Eyes of a Polar Bear This past April scientists with the U.S. Geological Survey applied video camera collars to four female polar bears on the sea ice north of Prudhoe Bay, Alaska and are releasing the first clips of footage that provide unique insight into the daily lives of the bears. The video shows polar bears interacting with other polar bears, eating, playing with food, and swimming on the sea ice in Alaska. These videos will be used by USGS scientists to understand polar bear behavior and energetics in an Arctic with declining sea ice.

National Climate Assessment Report, Includes Alaska Chapter

Native man looking out toward the sea. The U.S. Global Change Research Program released the third National Climate Assessment on May 6. This scientific report summarizes the impacts of climate change in the U.S., now and in the future, and was developed over four years by hundreds of the Nation's climate scientists and technical experts and informed by extensive input from the public. The report includes a chapter devoted to Alaska describing how Alaska has warmed twice as fast as the rest of the nation, bringing widespread impacts such as rapidly receding sea ice, retreating glaciers, thawing permafrost leading to more wildfire and affecting infrastructure and wildlife habitat, and rising ocean temperatures and acidification which will alter valuable marine fisheries. To read the report visit: http://nca2014.globalchange.gov/report.

USGS Commemorates the 1964 Alaskan Earthquake

Image of the state of Alaska with tsunami wave. 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.
