A Beach Probing System (BPS) for Determining Surf Zone Bathymetry, Currents, and Wave Heights from Measurements Offshore: Phase I - The Prototype Development and Capability Demonstration

Abstract

The six months reported herein have focused on finalizing the instrument and software design and field deployment strategy, and further developing and testing the inverse model for extracting depth profile estimates from infragravity wave measurements. A few of the more significant instrument design decisions are: We have chosen to use Sontek's Acoustic Doppler Velocimeter (ADV Ocean) as opposed to the Marsh-McBirney electro-magnetic current meter (EMCM); The ADV will mount on a pressure case that contains a pressure sensor, flash memory, Tattletale CPU, oven-controlled oscillator, compass/inclinometer, and batteries; There is an auxiliary port for the powering and collection of externally mounted instruments such as a conductivity/temperature sensor; The sensor package will be deployed mounted on the anchor pipe without the ability for in-situ adjustments of the package on the pipe.
