Microstructure Sensors Dedicated to Dr. Robert W. Stewart, one of the fathers of modern observations of ocean turbulence.

Direct Estimation of the Reynolds Stress Vertical Structure in the Nearshore
Publisher: American Meteorological Society
Abstract: Measurements of the vertical Reynolds stress components in the wave-dominated nearshore are required to diagnose momentum and turbulence dynamics. Removing wave bias from Reynolds stress estimates is critical to a successful ...
Vertical Heat-Flux Measurements from a Neutrally Buoyant Float
Publisher: American Meteorological Society
Abstract: A neutrally buoyant float instrumented to measure 1?5 m shear and stratification was deployed for ten days in a near-inertial critical layer at the base of a warm-core ring. Vertical velocity and temperature data, from ...
Vertical Structure of Dissipation in the Nearshore
Publisher: American Meteorological Society
Abstract: The vertical structure of the dissipation of turbulence kinetic energy was observed in the nearshore region (3.2-m mean water depth) with a tripod of three acoustic Doppler current meters off a sandy ocean beach. Surface ...
Comparison of BASS and VACM Current Measurements during STRESS
Publisher: American Meteorological Society
Abstract: Current measurements from a vector-averaging current meter (VACM) on a subsurface mooring and a benthic acoustic stress sensor (BASS) on a bottom tripod are compared to assess their relative accuracy. The instruments were ...
A Composite Spectrum of Vertical Shear in the Upper Ocean
Publisher: American Meteorological Society
Abstract: Results from three separate velocity profilers operated nearly simultaneously in the northwest Atlantic in 1975 are used to form a composite shear spectrum over vertical wavelengths from 100 m down to a few centimeters. ...
Near-Bottom Turbulence Measurements in a Partially Mixed Estuary: Turbulent Energy Balance, Velocity Structure, and Along-Channel Momentum Balance
Publisher: American Meteorological Society
Abstract: A set of moored, bottom-mounted and shipboard measurements, obtained in a straight section of the lower Hudson estuary during late summer and early fall of 1995, determine velocity, density, and along-channel pressure ...
Estimates of Kinetic Energy Dissipation under Breaking Waves
Publisher: American Meteorological Society
Abstract: The dissipation of kinetic energy at the surface of natural water bodies has important consequences for many Physical and biochemical processes including wave dynamics, gas transfer, mixing of nutrients and pollutants, and ...
