US Navy Navigates A Sea Change In The Arctic

April 17, 2012

The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism. Therefore, a more accessible Arctic not only means environmental changes, but also changes in our economy and our national security.

It is part of the U.S. Navy’s mission to provide stability wherever and whenever human activity is occurring in the maritime environment. Toward that mission, the Navy has created a task force, developed a roadmap, and employed a corps of geoscientists to synthesize scientific information about the changing Arctic. About halfway through the roadmap’s five-year timeline, planning continues and scientific challenges remain.
