It's true that ice is melting in the Arctic, but this doesn't mean the U.S. no longer needs icebreaker ships to operate in the region. And right now, the U.S. needs more than what it currently has.
As global temperatures rise and arctic ice melts, more ships are taking advantage of expedient, yet dangerous ocean routes that are opening in the polar region.
Scientists from the U.S. Naval Research Laboratory Marine Geosciences Division are assisting NASA, the US Army Cold Regions Research and Engineering Laboratory (CRREL) and the European Space Agency (ESA) in developing more accurate monitoring and sustainable forecasting of Arctic sea ice.
