The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Internal Wave Strain Fine-Structure Vertical Spectra
2009/4/2
Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The f...
Observations of Near-Surface Oceanic Velocity Strain-Rate Variability during and after Storm Events
Near-Surface Oceanic Velocity Strain-Rate Variability Storm Events
2009/2/10
During August of 1977, a series of repeated profiles of the upper ocean were made at Ocean Station Papa (145°W, 50°N) with a velocity/temperature microstructure profiler. A strong correlation of wind-...
Anticyclonic Lenses in Large-Scale Strain and Shear
Anticyclonic Lenses Large-Scale Strain shearing flow
2009/1/7
A three-layer model is used to study the effects of pure strain flow and simple shearing flow on isolated, anticyclonic, baroclinic vortices such as Mediterranean salt lenses. Exact steady solutions a...
Strain：Observations of the Vertical Gradient of Isopycnal Vertical Displacement

2008/12/23
In this work a profiling CTD, operated from the research platform FLIP, is used to monitor the fine-scale density field as a function of both depth and time. A sequence of 10 000 CTD profiles from the...
Estimates of the Vertical Wavenumber–Frequency Spectra of Vertical Shear and Strain
Garrett–Munk Vertical Wavenumber–Frequency Spectra Vertical Shear
2008/12/23
Measurements of vertical shear and strain were acquired from the research platform FLIP during the PATCHEX experiment in October, 1986 (34°N, 127°W). Vertical sheer was shear from two separate Doppler...
Toward a Statistical Description of Finescale Strain in the Thermocline
Statistical Description Finescale Strain Thermocline
2008/12/22
The statistical properties of the oceanic finescale strain field are investigated. Strain information is derived from a set of 9000 CTD profiles from the surface to 560-m depth, obtained from the Rese...
Shear, Strain, and Richardson Number Variations in the Thermocline. Part II: Modeling Mixing
Richardson Number Variations Thermocline Modeling Mixing
2008/11/12
Gregg has provided observational evidence that averaged estimates of dissipation, , vary approximately as the square of the internal wave field energy level E2. He notes that the finding is consiste...

Surface Waves Processes Experiment isopycnal-following frames Thermocline
2008/11/12
Quasi-continuous depth–time observations of shear (5.5-m, 6-min resolution) and strain, (η/z, (2-m, 2.1- min resolution) obtained from the R/P FLIP are applied to a study of Richardson number (Ri) sta...
