Chief of Naval Operations Adm. Gary Roughead speaks with personnel at the Applied Physics Lab Ice Station while touring the camp in the Arctic Ocean during Ice Exercise 2009. ICEX is a two-week training exercise about 200 miles from the north coast of Alaska, near Prudhoe Bay. Two Los Angeles-class submarines, USS Helena and USS Annapolis, will participate in the exercise with researchers from the University of Washington Applied Physics Laboratory and personnel from the Navy Arctic Submarine Laboratory.
