  • Generalized conditions for hydraulic criticality of oceanic overflows 

    Pratt, Lawrence J.; Helfrich, Karl R. (American Meteorological Society, 2005-10)
    Two methods for assessing the hydraulic criticality of an observed or modeled overflow are discussed. The methods are valid for single-layer deep flows with arbitrary potential vorticity and cross section. The first method ...
  • Generation and maintenance of recirculations by Gulf Stream instabilities 

    Beliakova, Natalia Y. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-02)

    Scotti, Alberto; Beardsley, Robert C.; Butman, Bradford (American Geophysical Union, 2007-10-02)
    During the summer, nonlinear internal waves (NLIWs) are commonly observed propagating in Massachusetts Bay. The topography of the area is unique in the sense that the generation area (over Stellwagen Bank) is only 25 km ...
  • Generation of mid-ocean eddies : the local baroclinic instability hypothesis 

    Arbic, Brian K. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2000-08)
    The plausibility of local baroclinic instability as a generation mechanism for midocean mesoscale eddies is examined with a two-layer, quasi-geostrophic (QG) model forced by an imposed, horizontally homogeneous, vertically ...
  • The generation, energetics and propagation of internal tides in the western North Atlantic Ocean 

    Hendry, Ross MacRae (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-04)
    This thesis reports on an investigation into the structure, energetics and propagation of tidal frequency internal waves. Data from Site D, near the New England continental slope, Muir Seamount northeast of Bermuda, and ...
  • Geostrophic vortex dynamics 

    Polvani, Lorenzo M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-08)
    By generalizing the method of contour dynamics to the quasigeostrophic two layer model, we have proposed and solved a number of fundamental problems in the dynamics of rotating and stratified vorticity fields. A variety ...
  • Gibraltar experiment : summary of the field program and initial results of the Gibraltar experiment 

    Kinder, Thomas H.; Bryden, Harry L. (Woods Hole Oceanographic Institution, 1988-08)
    During the period October 1985 to October 1986 a large group of oceanographers collaborated in an intensive field effort called the Gibraltar Experiment. Scientists from Morocco, Spain, France, the United Kingdom, Canada ...
  • Global barotropic variability of the ocean in response to atmospheric forcing based on multichannel regression and Kalman filter techniques 

    Chechelnitsky, Michael Y. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-05)
    TOPEX/POSEIDON altimetry data are employed in the analysis of the global ocean response to atmospheric forcing. We use two different approaches to test the hypothesis that the global sea surface height variability can ...
  • Global distribution of the decay timescale of mixed layer inertial motions observed by satellite-tracked drifters 

    Park, Jong Jin; Kim, Kuh; Schmitt, Raymond W. (American Geophysical Union, 2009-11-05)
    The decay timescale of mixed layer inertial amplitudes has been estimated from satellite tracked drifter trajectories from 1990 to 2004 as the e-folding timescale of the temporal correlation functions. The decay timescales ...
  • The global oceanic freshwater cycle : a state-of-the-art quantification 

    Schanze, Julian J.; Schmitt, Raymond W.; Yu, Lisan (Sears Foundation for Marine Research, 2010-05-01)
    The current capabilities of quantifying the oceanic freshwater cycle are shown based on new observations from satellite data and re-analysis models for evaporation and precipitation over the ocean. For this purpose, we ...
  • Global patterns of diapycnal mixing from measurements of the turbulent dissipation rate 

    Waterhouse, Amy F.; MacKinnon, Jennifer A.; Nash, Jonathan D.; Alford, Matthew H.; Kunze, Eric; Simmons, Harper L.; Polzin, Kurt L.; St. Laurent, Louis C.; Sun, Oliver M. T.; Pinkel, Robert; Talley, Lynne D.; Whalen, Caitlin B.; Huussen, Tycho N.; Carter, Glenn S.; Fer, Ilker; Waterman, Stephanie N.; Naveira Garabato, Alberto C.; Sanford, Thomas B.; Lee, Craig M. (American Meteorological Society, 2014-07)
    The authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect measurements of mixing obtained ...
  • A global relationship between the ocean water cycle and near-surface salinity 

    Yu, Lisan (American Geophysical Union, 2011-10-18)
    Ocean evaporation (E) and precipitation (P) are the fundamental components of the global water cycle. They are also the freshwater flux forcing (i.e., E-P) for the open ocean salinity. The apparent connection between ocean ...

    Liu, Ling Ling; Huang, Rui Xin (American Meteorological Society, 2012-02-15)
