  • Differential Diffusion in Breaking Kelvin–Helmholtz Billows 
    Smyth, W. D.; Nash, J. D.; Moum, J. N. (American Meteorological Society, 2005-06)
    Direct numerical simulations are used to compare turbulent diffusivities of heat and salt during the growth and collapse of Kelvin–Helmholtz billows. The ratio of diffusivities is obtained as a function of buoyancy Reyno ...
  • Energy transformations and dissipation of nonlinear internal waves over New Jersey's continental shelf 
    Shroyer, E. L.; Moum, J. N.; Nash, J. D. (European Geosciences Union, 2010-08-30)
    The energetics of large amplitude, high-frequency nonlinear internal waves (NLIWs) observed over the New Jersey continental shelf are summarized from ship and mooring data acquired in August 2006. NLIW energy was typical ...
  • Energy Transport by Nonlinear Internal Waves 
    Moum, J. N.; Klymak, J. M.; Nash, J. D.; Perlin, A.; Smyth, W. D. (American Meteorological Society, 2007-07)
    See Article for Abstract.
  • Internal‐tide energy over topography 
    Kelly, S. M.; Nash, J. D.; Kunze, E. (American Geophysical Union, 2010-06-19)
    The method used to separate surface and internal tides ultimately defines properties such as internal‐tide generation and the depth structure of internal‐tide energy flux. Here, we provide a detailed analysis of severa ...
  • Internal‐tide generation and destruction by shoaling internal tides 
    Kelly, S. M.; Nash, J. D. (American Geophysical Union, 2010-12-10)
    Internal‐tide generation is usually predicted from local topography, surface tides, and stratification. However, internal tides are often observed to be unrelated to local spring‐neap forcing, appearing intermittently ...
  • Mixing Measurements on an Equatorial Ocean Mooring 
    Moum, J. N.; Nash, J. D. (American Meteorological Society, 2009-02)
    Vaned, internally recording instruments that measure temperature fluctuations using FP07 thermistors, including fluctuations in the turbulence wavenumber band, have been built, tested, and deployed on a Tropical Atmosphe ...
  • Mode 2 waves on the continental shelf: Ephemeral components of the nonlinear internal wavefield 
    Shroyer, E. L.; Moum, J. N.; Nash, J. D. (American Geophysical Union, 2010-07-02)
    Shoreward propagating, mode 2 nonlinear waves appear sporadically in mooring records obtained off the coast of New Jersey in the summer of 2006. Individual mode 2 packets were tracked between two moorings separated by ...
  • Narrowband Oscillations in the Upper Equatorial Ocean. Part I: Interpretation as Shear Instabilities 
    Moum, J. N.; Nash, J. D.; Smyth, W. D. (American Meteorological Society, 2011-03)
    Extended measurements of temperature fluctuations that include the turbulence wavenumber band have now been made using rapidly sampled fast thermistors at multiple depths above the core of the Equatorial Undercurrent on ...
  • Narrowband Oscillations in the Upper Equatorial Ocean. Part II: Properties of Shear Instabilities 
    Smyth, W. D.; Moum, J. N.; Nash, J. D. (American Meteorological Society, 2011-03)
    Narrowband oscillations observed in the upper equatorial Pacific are interpreted in terms of a random ensemble of shear instability events. Linear perturbation analysis is applied to hourly averaged profiles of velocity ...
  • Nonlinear internal waves over New Jersey's continental shelf 
    Shroyer, E. L.; Moum, J. N.; Nash, J. D. (American Geophysical Union, 2011-03-23)
    Ship and mooring data collected off the coast of New Jersey are used to describe the nonlinear internal wave (NLIW) field and the background oceanographic conditions that formed the waveguide on the shelf. The subinertia ...
  • Observations of Boundary Mixing over the Continental Slope 
    Moum, J. N.; Caldwell, D. R.; Nash, J. D.; Gunderson, G. D. (American Meteorological Society, 2002-07)
    Observations of mixing over the continental slope using a towed body reveal a great lateral extent (several kilometers) of continuously turbulent fluid within a few hundred meters of the boundary at depth 1600 m. The lar ...
  • Observations of Polarity Reversal in Shoaling Nonlinear Internal Waves 
    Shroyer, E. L.; Moum, J. N.; Nash, J. D. (American Meteorological Society, 2009-03)
    Observations off the New Jersey coast document the shoaling of three groups of nonlinear internal waves of depression over 35 km across the shelf. Each wave group experienced changing background conditions along its shor ...
  • Seafloor Pressure Measurements of Nonlinear Internal Waves 
    Moum, J. N.; Nash, J. D. (American Meteorological Society, 2008-02)
    Highly resolved pressure measurements on the seafloor over New Jersey’s continental shelf reveal the pressure signature of nonlinear internal waves of depression as negative pressure perturbations. The sign of the pertur ...
  • Topographically Induced Drag and Mixing at a Small Bank on the Continental Shelf 
    Moum, J. N.; Nash, J. D. (American Meteorological Society, 2000-08)
    Recent turbulence measurements over a small bank on the continental shelf off Oregon reveal a previously undetected site for intense mixing of the coastal ocean. The flow is hydraulically controlled and turbulence diffus ...
  • Vertical heat flux and lateral mass transport in nonlinear internal waves 
    Shroyer, E. L.; Moum, J. N.; Nash, J. D. (American Geophysical Union, 2010-04-24)
    Comprehensive observations of velocity, density, and turbulent dissipation permit quantification of the nonlinear internal wave (NLIW) contribution to vertical heat flux and lateral mass transport over New Jersey’s sh ...
