The Role of Internal Tides in Mixing the Deep Ocean
Publisher: American Meteorological Society
Abstract: Internal wave theory is used to examine the generation, radiation, and energy dissipation of internal tides in the deep ocean. Estimates of vertical energy flux based on a previously developed model are adjusted to account ...
Estimates of Power Consumed by Mixing in the Ocean Interior
Publisher: American Meteorological Society
Abstract: Much attention has focused on the power required for driving mixing processes in the ocean interior, the thermohaline circulation, and the related meridional overturning circulation (MOC). Recent estimates range from roughly ...
The Contribution of Salt Fingers to Vertical Mixing in the North Atlantic Tracer Release Experiment
Publisher: American Meteorological Society
Abstract: The North Atlantic Tracer Release Experiment (NATRE) was performed in an area moderately favorable to salt fingers. However, the classic finger signature of a distinct thermohaline staircase caused by upgradient density ...
Buoyancy Forcing by Turbulence above Rough Topography in the Abyssal Brazil Basin
Publisher: American Meteorological Society
Abstract: Observations of turbulent dissipation above rough bathymetry in the abyssal Brazil Basin are presented. Relative to regions with smooth bathymetry, dissipation is markedly enhanced above rough topography of the Mid-Atlantic ...
Scaling Turbulent Dissipation in the Transition Layer
Publisher: American Meteorological Society
Abstract: ata from three midlatitude, month-long surveys are examined for evidence of enhanced vertical mixing associated with the transition layer (TL), here defined as the strongly stratified layer that exists between the well ...
Biases in Thorpe-Scale Estimates of Turbulence Dissipation. Part I: Assessments from Large-Scale Overturns in Oceanographic Data
Publisher: American Meteorological Society
Abstract: ceanic density overturns are commonly used to parameterize the dissipation rate of turbulent kinetic energy. This method assumes a linear scaling between the Thorpe length scale LT and the Ozmidov length scale LO. Historic ...
Abyssal Mixing in the Brazil Basin
Publisher: American Meteorological Society
Abstract: One of the major objectives of the Deep Basin Experiment, a component of the World Ocean Circulation Experiment, was to quantify the intensity and spatial distribution of deep vertical mixing within the Brazil Basin. In ...
Moored Turbulence Measurements Using Pulse-Coherent Doppler Sonar
Publisher: American Meteorological Society
Global Patterns of Diapycnal Mixing from Measurements of the Turbulent Dissipation Rate
Publisher: American Meteorological Society
Abstract: he 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 ...
Climate Process Team on Internal-Wave Driven Ocean Mixing
Publisher: American Meteorological Society
Abstract: cent advances in our understanding of internal-wave driven turbulent mixing in the ocean interior are summarized. New parameterizations for global climate ocean models, and their climate impacts, are introduced.
