Particle Dynamics in the Bottom Boundary Layer at the Coastal Mixing and Optics Experiment Site

Abstract

My long-term goal is to generate measurements of particle concentration and settling velocities as function of particle sizes; these data are central to modeling sediment transport in the BBL. My objectives were to (a) measure the size-dependent particle concentration and settling velocities with the use of newly developed instruments funded through this program. These instruments, LISST- 100 and LISST-ST employ the principles of multi-angle light scattering and a mathematical inversion of these measurements for estimating the particle concentration in 32 log-spaced (equi-phi) intervals. The measurements were to be made from a tripod placed on the bottom; (b) the second objective was to examine the measurements in conjunction with bottom stress measurements made by the BASS velocimeter array placed nearby.
