Optics, Acoustics, and Stress in a Nearshore Bottom Nepheloid Layer
The approach is to obtain measurements that will permit comparisons of temporal evolution of bottom stress, suspended particle size, and optical and acoustical properties in the bottom boundary layer. The instrumentation is mounted on bottom tripods and an I-beam frame. The “OASIS” tripod includes a 9wavelength optical attenuation and absorption meter (WetLabs ac-9, with automated dissolved mea...

متن کاملBenthic storms: temporal variability in a deep-ocean nepheloid layer.
Time series measurements of light scattering were made for 2(1/2) months at 20 meters above the bottom in the western North Atlantic. The highest values recorded with the nephelometer exceeded all previous measurements worldwide. Rapid changes indicated a high degree of activity near the sea floor, and some increases may have been related to atmospheric storms.
متن کاملStratification Effects in a Bottom Ekman Layer
A stratified bottom Ekman layer over a nonsloping, rough surface is studied using a three-dimensional unsteady large eddy simulation to examine the effects of an outer layer stratification on the boundary layer structure. When the flow field is initialized with a linear temperature profile, a three-layer structure develops with a mixed layer near the wall separated from a uniformly stratified o...
متن کاملA traversing system to measure bottom boundary layer hydraulic properties
This study describes a new convenient and robust system developed to measure benthic boundary layer properties, with emphasis placed on the determination of bed shear stress and roughness height distribution within estuarine systems by using velocity measurements. This system consisted of a remotely operated motorised traverser that allowed a single ADV to collect data between 0 and 1 m above t...
