  • On the pathways of the return flow of the meridional overturning circulation in the tropical Atlantic 

    Jochum, Markus (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-06)
    A numerical model of the tropical Atlantic ocean is used to investigate the upper layer pathways of the Meridional Overturning Circulation (MOC) in the tropical Atlantic. The main focus of this thesis is on those parts ...
  • On the propagation of free topographic Rossby waves near continental margins 

    Ou, Hsien Wang (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-04)
    Observational work by Thompson (1977) and others has demonstrated that free topographic Rossby waves propagate northward up the continental rise south of New England. To study the dynamical implications of these waves ...

    Le Moigne, Frederic A. C.; Sanders, Richard J.; Villa-Alfageme, Maria; Martin, Adrian P.; Pabortsava, Katsiaryna; Planquette, Helene; Morris, Paul J.; Thomalla, Sandy J. (American Geophysical Union, 2012-08-11)
    The role of biominerals in driving carbon export from the surface ocean is unclear. We compiled surface particulate organic carbon (POC), and mineral ballast export fluxes from 55 different locations in the Atlantic and ...
  • On the pulmonary toxicity of oxygen : III. The induction of oxygen dependency by oxygen use 

    Shanklin, D. Radford (2010-05)
    Oxygen is central to the development of neonatal lung injury. The increase in oxygen exposure of the neonatal lung during the onset of extrauterine air breathing is an order of magnitude, from a range of 10-12 to 110-120 ...
  • On the pulmonary toxicity of oxygen. 4. The thyroid arena 

    Shanklin, D. Radford (2011-11)
    Normally developed thyroid function is critical to the transition from fetal to neonatal life with the onset of independent thermoregulation, the most conspicuous of the many ways in which thyroid secretions act throughout ...
  • On the pulmonary toxicity of oxygen. 5. Electronic structure and the paramagnetic property of oxygen 

    Shanklin, D. Radford (2012-06-01)
    Oxygen uptake by the pulmonary circulation is a chemical reaction. The physicochemical attributesof oxygen are critical when studying pulmonary oxygen toxicity. Extent of lung injury depends onthe percentage of oxygen in ...
  • On the relationship between synoptic wintertime atmospheric variability and path shifts in the Gulf Stream and the Kuroshio Extension 

    Joyce, Terrence M.; Kwon, Young-Oh; Yu, Lisan (American Meteorological Society, 2009-06-15)
    Coherent, large-scale shifts in the paths of the Gulf Stream (GS) and the Kuroshio Extension (KE) occur on interannual to decadal time scales. Attention has usually been drawn to causes for these shifts in the overlying ...
  • On the response of a buoyant plume to downwelling-favorable wind stress 

    Moffat, Carlos F.; Lentz, Steven J. (American Meteorological Society, 2012-07)
    Here, the response of a coastally trapped buoyant plume to downwelling-favorable wind forcing is explored using a simplified two-dimensional numerical model and a prognostic theory for the resulting width, depth, and density ...
  • On the role of eddies and surface forcing in the heat transport and overturning circulation in marginal seas 

    Spall, Michael A. (American Meteorological Society, 2011-09-15)
    The factors that determine the heat transport and overturning circulation in marginal seas subject to wind forcing and heat loss to the atmosphere are explored using a combination of a high-resolution ocean circulation ...
  • On the role of topography and of boundary forcing in the ocean circulation 

    Cessi, Paola (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-08)
    This thesis consists of two loosely related problems, both of which analyze some consequences of the failure of Sverdrup relation. In the first part, Chapters 2 and 3, the Sverdrup relation is invalidated because substantial ...
  • On the sedimentological origin of down-core variations of bulk sedimentary nitrogen isotope ratios 

    Kienast, Markus; Higginson, M. J.; Mollenhauer, Gesine; Eglinton, Timothy I.; Chen, Min-Te; Calvert, Stephen E. (American Geophysical Union, 2005-05-27)
    The bulk sedimentary nitrogen isotopic composition of two cores from nearby sites on the northern slope of the South China Sea (Site 17940 and Ocean Drilling Program (ODP) Site 1144) differs by up to >2‰ during the last ...
  • On the stability of ocean overflows 

    Pratt, Lawrence J.; Helfrich, Karl R.; Leen, David (Cambridge University Press, 2008-04-25)
    The stability of a hydraulically driven sill flow in a rotating channel with smoothly varying cross-section is considered. The smooth topography forces the thickness of the moving layer to vanish at its two edges. The basic ...
  • On the statistics of magnetotelluric rotational invariants 

    Chave, Alan D. (Oxford University Press on behalf of The Royal Astronomical Society, 2013-10-25)
    The statistical properties of the Swift skew, the phase-sensitive skew and the WAL invariants I1−I7 and Q are examined through analytic derivation of their probability density functions and/or simulation based on a Gaussian ...
  • On the structure of the trade wind moist layer 

    Malkus, Joanne Starr (Woods Hole Oceanographic Institution, 1957-01)

  • On the structure of the trade wind moist layer 

    Malkus, Joanne Starr (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1958-08)
    The trade-wind moist layer is itself subdivided in the vertical into two superposed layers of different convective regime, because of the occurrence of water vapor condensation at about 600-700 m above the tropical oceans. ...
  • On the structure of trade-wind air below cloud
