Abstract: This paper describes hardware and software modifications to a commercial incoherent acoustic Doppler current profiler that allow it to be used as a survey tool for measurement of turbulent velocity fields associated with ...

Abstract: Turbulence in the ocean results from many different processes operating over a wide range of space scales and timescales, with spatial and temporal variability particularly extreme in coastal oceans. If the origins and ...

Abstract: This work investigates the use of different vertical eddy diffusivity for salt (Ds) and for temperature (DT) in a coarse-resolution primitive equation ocean model. The diffusivity ratio d ≡ Ds/DT is taken from a range 0.5 ...

Abstract: The authors report direct measurements of density flux at a single depth in a turbulent tidal flow, made by towing a CTD beside the vertical beam of a modified acoustic Doppler current profiler. The direct flux estimates ...

Abstract: The potential for differential turbulent transport of oceanic temperature (T) and salinity (S) is explored using three-dimensional direct numerical simulations of decaying stratified turbulence. The simulations employ a ...

Abstract: The potential for differential turbulent transport of oceanic temperature (T) and salinity (?) is explored using three-dimensional direct numerical simulations of decaying stratified turbulence. The simulations employ a ...

Abstract: A global ocean model is described in which parameterizations of diapycnal mixing by double-diffusive fingering and layering are added to a stability-dependent background turbulent diffusivity. Model runs with and without ...

Abstract: A free-falling instrument has been built to measure temperature, salinity and turbulent shear from near surface to within 15 cm of the ocean bottom. A probe guard mounted at the lower end of the instrument protects sensitive ...
