On the Effect of Dissipation on Seasonal Thermocline Models
Seasonal Thermocline Models dissipation
2009/2/11
This paper considers several parameterizations of dissipation in a Kraus-Turner (1967) seasonal mixed-layer model with no net annual surface buoyancy flux. By studying the behavior of the turbulent ki...
Measurements of Gulf Stream Meandering and Evidence of Seasonal Thermocline Development Using Long-Range Acoustic Transmissions
Gulf Stream Meandering Seasonal Thermocline Development Long-Range Acoustic Transmissions
2009/2/6
Phase-coded signals with 60 rms resolution were transmitted twice weekly for several months from acoustic sources at 2000 m depth in the Sargasso Sea to three bottom-mounted receives designed as West,...
Richardson Number Statistics in the Seasonal Thermocline
Richardson Number Statistics Seasonal Thermocline
2009/1/16
Statistics of Richardson number in the seasonal thermocline are determined for a simple model and from experiments over the continental shelf. The model consists of normally distributed and uncorrelat...
A dye dispersion experiment was performed in September, 1979, in the open ocean approximately 180 km off the east coast of Florida. An initially vertical sheet of dye extending from about 60 to 100 me...
Observations of Small-Scale Mixing Processes in the Seasonal Thermocline, Part II：Wave Breaking
Small-Scale Mixing Processes Seasonal Thermocline Wave Breaking
2009/1/8
Towed thermistor chain measurements are used to describe a large patch of ocean fine- and microstructure. In contrast to the relatively quiescent salt-fingering conditions of Part I, the 3-km long by ...
Observations of Small-Scale Mixing Processes in the Seasonal Thermocline. Part I：Salt Fingering
Small-Scale Mixing Processes Seasonal Thermocline Salt Fingering
2009/1/8
Towed conductivity microstructure measurements are examined for evidence of salt fingering in the seasonal thermocline of the Sargasso Sea. Patches of limited-amplitude, narrow-bandwidth signals occur...
A Synoptic Map of Isopycnic Potential Vorticity in the Seasonal Thermocline
isopycnic potential vorticity Seasonal Thermocline
2008/12/30
The distribution of isopycnic potential vorticity (IPV) has been mapped in the seasonal thermocline from a single ship using relative velocity measurements plus absolute ship motion, and density profi...
Horizontal Distribution and Characteristics of Shear Layers in the Seasonal Thermocline
Horizontal Distribution Seasonal Thermocline Shear Layers
2008/12/30
High-resolution velocity shear, CTD, and microstructure measurements were made simultaneously from the research submarine Dolphin in Monterey Bay in October 1984. During three consecutive dives, the D...
Mesoscale Upwelling and Density Finestructure in the Seasonal Thermocline—A Dynamical Model
Mesoscale turbulence Seasonal Thermocline—A Dynamical Model Mesoscale Upwelling
2008/12/23
Mesoscale turbulence is modeled in terms of an unstable potential vorticity front. The model integration starts from a purely zonal, 60-km-wide geostrophically balanced jet, on which is superimposed a...
Direct Estimation of Heat Flux in a Seasonal Thermocline
Heat Flux Seasonal Thermocline direct measurement
2008/12/17
This paper reports on a direct measurement of the turbulent heat flux. The sampling was from a submarine that used a conventional airfoil probe to measure the vertical component of turbulent velocity ...
