Melting sea ice is causing the Arctic to change, opening up sea passages and altering currents. Now, scientists have found that storms have the potential to create Arctic swell due to these newly open spaces and that these huge waves could add another unpredictable element to the region.
Arctic ice once retreated less than 100 miles from the shore. Yet in 2012, the ice retreated more than 1,000 miles. This, in turn, changed the dynamic of the region. Wind blowing across an open expanse of water can create whitecaps and then small waves; these, in turn, can form large swells.
