    Price, James F. (Copernicus Publications on behalf of the European Geosciences Union, 2009-05-05)
    The ocean thermal field is often represented in hurricane-ocean interaction by a metric termed upper Ocean Heat Content (OHC), the vertical integral of ocean temperature in excess of 26°C. High values of OHC have proven ...

  • Midlatitude wind stress–sea surface temperature coupling in the vicinity of oceanic fronts 

    Spall, Michael A. (American Meteorological Society, 2007-08-01)
    The influences of strong gradients in sea surface temperature on near-surface cross-front winds are explored in a series of idealized numerical modeling experiments. The atmospheric model is the Naval Research Laboratory ...
  • Mixing across the Arctic Ocean : microstructure observations during the Beringia 2005 Expedition 

    Rainville, Luc; Winsor, Peter (American Geophysical Union, 2008-04-30)
    Turbulent-scale temperature and conductivity were measured during the pan-arctic Beringia 2005 Expedition. The rates of dissipation of thermal variance and diapycnal diffusivities are calculated along a section from Alaska ...
  • Mixing and dynamics of the Mediterranean outflow 

    Baringer, Molly O. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-10)
    Hydrographic and expendable current profiler (XCP) data taken during the Gulf of Cadiz Expedition in September 1988 are analyzed to diagnose the mixing and dynamics of the Mediterranean outflow. The overall structure of ...
  • Mixing and entrainment in hydraulically driven stratified sill flows 

    Nielsen, Morten Holtegaard; Pratt, Lawrence J.; Helfrich, Karl R. (Cambridge University Press, 2004-09-09)
    The investigation involves the hydraulic behaviour of a dense layer of fluid flowing over an obstacle and subject to entrainment of mass and momentum from a dynamically inactive (but possibly moving) overlying fluid. An ...

    Peters, Hartmut; Johns, William E.; Bower, Amy S.; Fratantoni, David M. (American Meteorological Society, 2005-05)
    When the salty and heavy water of the Red Sea exits from the Strait of Bab el Mandeb, it continues downslope into the Gulf of Aden mainly along two channels. The 130-km-long “Northern Channel” (NC) is topographically ...
