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 Sonteks 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, compassinclinometer, and batteries There is an auxiliary port for the powering and collection of externally mounted instruments such as a conductivitytemperature 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.
