Microstructure and Intrusions in the California Current
Publisher: American Meteorological Society
Abstract: 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 ?irregularly steppy? ...
Variations in the Intensity of Small-Scale Mixing in the Main Thermocline
Publisher: American Meteorological Society
Abstract: Three cruises to the same site in the central North Pacific (28°N, 155°W) found naked differences in the levels of small-scale turbulent activity as indicated by spectra of temperature profiles. Considering the data from ...
Microstructure Patches in the Thermocline
Publisher: American Meteorological Society
Abstract: Profiles of temperature microstructure have been found to exhibit strong intermittence in the distribution of ?, the rate of diffusive smoothing of temperature fluctuations. Records from the main thermocline in the subtropical ...
The Effects of Bias Error and System Noise on Parameters Computed from C, T, P and V Profiles
Publisher: American Meteorological Society
Abstract: The development of high-resolution profiling instruments has made possible the computation of quantities such as the stability parameter N2 and the Richardson number Ri over scales of less than a meter. Quality control of ...
A Comparison of Finestructure Spectra from the Main Thermocline
Publisher: American Meteorological Society
Abstract: Large numbers of STD casts taken during five cruises to the same location in the central North Pacific permitted the separation of the temperature profile into mean T? (z) and fluctuating T?(z) components. Spectra of the ...
Uncertainties and Limitations in Measuring ϵ and χT
Publisher: American Meteorological Society
Abstract: Extending the range of microstructure measurements from the upper thermocline of the open ocean to shallow waters near shore and to the abyss has greatly increased in the range of turbulent intensities being observed. As ...
Finestructure and Microstructure Observations During the Passage of a Mild Storm
Publisher: American Meteorological Society
Abstract: 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, maximum winds of 18 kt, ...
Entropy Generation In the Ocean by Small-Scale Mixing
Publisher: American Meteorological Society
Abstract: An expression that includes salt diffusion was developed and evaluated for the rate of entropy production σ in the ocean. The evaluation was done for mixing events produced by turbulent overturns and double diffusion. ...
Reversible and Irreversible Finestructure
Publisher: American Meteorological Society
Abstract: Various statistics of temperature profiles are examined in an attempt to distinguish irreversible structures due to mixing from reversible distortions induced by internal wave straining. Even if all the low gradient regions ...
Signatures of Mixing from the Bermuda Slope, the Sargasso Sea and the Gulf Stream
Publisher: American Meteorological Society
Abstract: Nearly simultaneous profiles of temperature microstructure and velocity shear were made adjacent to the island of Bermuda. Profiles with elevated microstructure levels were found in close association with regions of ...
