Abstract: 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 probe to the oceanic ...

Abstract: 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 and a thermistor probe ...

Abstract: Doubly diffusive convection and turbulence were measured from a submarine in a region where the mean gradients do not support doubly diffusive processes but intrusions provide favorable sites. The stability of the ...

Abstract: A towed body suitable for measuring oceanic velocity and temperature microstructure is described. The development was motivated by i) a requirement for long times series to produce statistically reliable estimates of ...

Abstract: Measurements of small-scale velocity and temperature fluctuations have been made from the research submarine Dolphin in the open ocean off San Diego, California. The important contribution of the submarine is that it ...

Abstract: The dissipation rate of kinetic energy, ?, was estimated from adjacent and simultaneous measurements with a submarine and a vertical profiler. The submarine cycled up and down through the water column measuring both a ...

Abstract: The effect of finite spatial resolution on the measured energy spectrum is examined via a parametric study using in situ particle image velocimetry (PIV) measurements performed in the bottom boundary layer on the Atlantic ...

Abstract: This paper introduces an oceanic particle image velocimetry (PIV) system that has been under development at The Johns Hopkins University over the past three years. PIV maps two components of the instantaneous velocity ...

Abstract: Thirteen profiles of the rate of viscous dissipation of turbulent kinetic energy &epsi? were made over the continental slope off Vancouver Island between 12 and 14 May 1980 in conjunction with CTD and moored current-meter ...
