We are all familiar with the irregular profiles from modern, high resolution conductivity-temperature-depth profilers (commonly called CTDs) freely falling vertical profilers, and towed thermistor cha...
Vertical Microstructure Measurements in the Central Worth Pacific
Vertical Microstructure Measurements Central Worth Pacific
2009/4/2
Temperature profiles were made, during a period of calm weather in early autumn, in the center of the subtropical gyre in the North Pacific with free-fall microstructure instruments as well as with co...
Measurements of the vertical component of the temperature gradient in Powell Lake show phenomena similar to those observed in the ocean. The gradient is an irregular function of depth, with temperatur...
A free-fall oceanographic instrument capable of producing direct estimates of the local rate of energy dissipation has been developed. The velocity sensor in an adaptation of the two-component airfoil...
Horizontal Coherence of Temperature Microstructure
Horizontal Coherence Temperature Microstructure
2009/3/24
Temperature gradient records from vertical lowerings of an array of four thermometers are used to trace microstructure features horizontally over a distance of 46 cm. Identifiable features are found t...
Microstructure and Intrusions in the California Current
Microstructure Intrusions California Current
2009/3/24
Two microstructure records taken at shallow depths off Cabo San Lucas, at the southern tip of Baja California, are compared. One is similar to records previously taken in the mid-gyre, and has an “irr...
Finestructure and Microstructure Observations During the Passage of a Mild Storm
Mild Storm microstructure observations Finestructure
2009/3/7
Finestructure and microstructure observations of temperature and salinity were made over a two-week period in late winter at a site in the central North Pacific, during which time a mild storm, maximu...
Repeated Profiling of Microstructure Lenses with a Midwater Float
Microstructure Lenses Midwater Float
2009/3/7
A freely drifting, midwater float equipped with a buoyancy controller has been developed and used to obtain 20 m profiles of temperature gradient (0.02 m resolution) and temperature (0.5 m resolution)...
Profiles of temperature microstructure have been found to exhibit strong intermittence in the distribution of χ, the rate of diffusive smoothing of temperature fluctuations. Records from the main ther...
Temperature Microstructure in the Equatorial Atlantic
Temperature Microstructure Equatorial Atlantic
2009/2/16
Vertical profiles of temperature microstructure were collected at seven sites in the equatorial Atlantic between 24°W and 33°W, 2°N and 1°20′S. The use of three identical temperature microstructure pr...
Alternative Interpretations for Microstructure Patches in the Thermocline
Microstructure Patches Thermocline
2009/2/7
Two interpretations of microstructure patches measured in the main thermocline of the North Pacific by Gregg (1980) are questioned. He concludes that the observed microstructure is not fossil-temperat...
Determination of the Rate of Dissipation of Turbulent Energy from Simultaneous Temperature and Velocity Shear Microstructure Measurements
Turbulent Energy Simultaneous Temperature Velocity Shear
2009/2/7
Spectra of turbulence have been examined for both temperature gradient and velocity shear. The data for this comparison are 10–15 m segments of vertical microstructure profiles (at depths of 5–100 m) ...
Fine and Microstructure Observations on a Hydrographic Section from the Azores to the Flemish Cap
conductivity-temperature-depth Flemish Cap Hydrographic Section
2009/2/5
Continuous conductivity-temperature-depth-dissolved-oxygen (CTD) data are used to investigate the spatial distribution of fine and microstructure between the Azores and Flemish Cap. The CTD data are u...
