    • From salty to fresh—salinity processes in the Upper-ocean Regional Study-2 (SPURS-2) : diagnosing the physics of a rainfall-dominated salinity minimum 

      Schmitt, Raymond W.; Asher, William; Bingham, Frederick; Carton, James A.; Centurioni, Luca R.; Farrar, J. Thomas; Gordon, Arnold L.; Hodges, Benjamin A.; Jessup, Andrew T.; Kessler, William S.; Rainville, Luc; Shcherbina, Andrey Y. (The Oceanography Society, 2015-03)
      One of the notable features of the global ocean is that the salinity of the North Atlantic is about 1 psu higher than that of the North Pacific. This contrast is thought to be due to one of the large asymmetries in the ...

      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)
      This thesis studies the problems of generation and maintenance of recirculations by Gulf Stream instabilities. Observations show that the horizontal structure of the jet and its recirculations suffer significant changes ...
    • Generation and propagation of nonlinear internal waves in Massachusetts Bay 

      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 : a plan for dynamic and kinematic investigations of strait mixing, exchange and turbulence 

      Bryden, Harry L.; Kinder, Thomas H. (Woods Hole Oceanographic Institution, 1986-08)
      The flow through the Strait of Gibraltar has always held a special fascination for oceanographers. Attempts to understand and measure the strong currents in the Strait stimulated many of the early advances in oceanography ...
    • 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 ...

      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 ...
