Department members investigate the dynamics and thermodynamics of ocean circulation. They work globally from the Arctic to the Antarctic and from the Strait of Gibraltar to the Philippine shelf on the full range of oceanic processes, from mixing on centimeter scales to heat balance on the global scale.

  • Anomalous water mass distributions at 55W in the North Atlantic in 1977 

    McCartney, Michael S.; Worthington, L. Valentine; Raymer, Mary E. (Woods Hole Oceanographic Institution, 1980-12)
    A hydrographic section made in July 1977 from the research vessel KNORR revealed a large-scale meridional distortion of the normal water mass distributions at 55W in the North Atlantic. Cells of pure Labrador Sea Water ...

  • Density-diffusive model of the Ninetyeast Ridge current 

    Johnson, Eric S.; Warren, Bruce A. (Woods Hole Oceanographic Institution, 1980-11)
    A model for the structure of deep western boundary currents, based on linear momentum equations and lateral mixing of density, is applied to data from a recent section across the Ninetyeast Ridge current in the eastern ...
  • Gulf Stream ring trajectories

    During the period 1976-78, the movement of 14 Gulf Stream rings, including two anticyclonic and 12 cyclonic rings, was measured with satellite-tracked free-drifting buoys. The buoys in the cyclonic rings showed a tendency ...
  • The physical structure and life history of cyclonic Gulf Stream ring, Allen 

    Richardson, Philip L.; Maillard, Catherine; Sanford, Thomas B. (Woods Hole Oceanographic Institution, 1980-11)
    A cyclonic Gulf Stream ring, Allen, was followed over its life from September 1976 to April 1977 in the region north of Bermuda. Conductivity, temperature, and depth; expendable bathythermograph; and velocity profile ...
  • Critical layers and the Garrett-Munk spectrum 

    Ruddick, Barry R. (Woods Hole Oceanographic Institution, 1980-11)
    The effects of critical level absorption of oceanic internal waves by a mean flow are estimated using the Garrett and Munk (1975) model spectrum. The horizontal currents of the wave field are found to be more intense ...
  • Eddies off the Somali coast during the southwest monsoon 

    Bruce, John G. (Woods Hole Oceanographic Institution, 1980-11)
    The development and decay of the large eddy in the northern Somali Basin and its smaller associated eddies each southwest monsoon in the northwestern Indian Ocean has been monitored for four consecutive years by a time ...
  • On production and dissipation of thermal variance in the oceans 

    Joyce, Terrence M. (Woods Hole Oceanographic Institution, 1980-11)
    An integral relationship is derived expressing the total dissipation of thermal variance by oceanic microstructure in terms of the large-scale forcing at the ocean surface by air/sea heat exchange. The net heat gain by ...
  • Observed and numerically simulated kinetic energies for MODE eddies 

    Schmitz, William J.; Owens, W. Brechner (Woods Hole Oceanographic Institution, 1980-11)
    It is demonstrated that the outcome of an intercomparison between data and the vertical distribution of eddy kinetic energy predicted by a previously developed numerical model of the MODE area is frequency dependent. In ...
  • Internal waves, finestructure, mocrostructure, and mixing in the ocean 

    Gregg, Michael C.; Briscoe, Melbourne G. (Woods Hole Oceanographic Institution, 1980-11)
    Progress in measuring, interpreting, and understanding oceanic internal gravity waves and fine and microstructure is reviewed; we emphasize the quadrennium 1975-1978. The context is how these subjects contribute to ...
  • Eddy memory mode of multidecadal variability in residual-mean ocean circulations with application to the Beaufort Gyre 

    Manucharyan, Georgy E.; Thompson, Andrew F.; Spall, Michael A. (American Meteorological Society, 2017-04-12)
    Mesoscale eddies shape the Beaufort Gyre response to Ekman pumping, but their transient dynamics are poorly understood. Climate models commonly use the Gent–McWilliams (GM) parameterization, taking the eddy streamfunction ...
  • Surface cooling, winds, and eddies over the continental shelf 

    Brink, Kenneth H. (American Meteorological Society, 2017-04-17)
    Models show that surface cooling over a sloping continental shelf should give rise to baroclinic instability and thus tend toward gravitationally stable density stratification. Less is known about how alongshore winds ...
  • Pathways for the export of Arctic change into the North Atlantic 

    Ramsey, Andree L.; Straneo, Fiamma (Woods Hole Oceanographic Institution, 2018-01)
    The goal of the Pathways for the Export of Arctic Change into the North Atlantic project was to measure the exchange between the Hudson Bay System and the Labrador Sea, which occurs in the Hudson Strait. This exchange ...

    Passaggia, Pierre-Yves; Helfrich, Karl R.; White, Brian L. (2018-01-10)
    The dynamics of perturbations to large-amplitude Internal Solitary Waves (ISW) in two-layered ows with thin interfaces is analyzed by means of linear optimal transient growth methods. Optimal perturbations are computed ...
  • Internal solitary wave generation by tidal flow over topography 

    Grimshaw, Roger H. J.; Helfrich, Karl R. (2017-12-21)
    Oceanic internal solitary waves are typically generated by barotropic tidal flow over localised topography. Wave generation can be characterised by the Froude number F = U/c(0), where U is the tidal flow amplitude and c(0) ...
