Arctic pressure ridges studied


  • Anonymous


A way to break passage and maintain shipping lanes through the massive ice blockades of the Arctic Ocean is the objective of a scientific research project sponsored by the U.S. Coast Guard. Pressure ridges created by the piling-up of ice floes have an average dimension of 15 feet above to 40 feet below the surface of the water, but may range from 40 feet above to 160 feet below.
