      Kida, Shinichiro; Price, James F.; Yang, Jiayan (American Meteorological Society, 2008-04)
      The oceanic response to overflows is explored using a two-layer isopycnal model. Overflows enter the open ocean as dense gravity currents that flow along and down the continental slope. While descending the slope, overflows ...
