Submitted in partial fulfillment of the requirements for the degree of Master of Science at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution September 2008 The mid-to-deep Arctic Ocean is generally characterized by a cyclonic circulation, contained along shelves and ridges.
