Power Distribution and Data Acquisition for a Free-falling Oceanographic Profiling System
Abstract
The long-term goal of our research group is quantification of the interactions between small-scale biological and physical processes within the upper ocean. This project has addressed that goal by expanding our technical capabilities for vertical profiling of sub-1m scale bio-optical and physical properties. The success of high-resolution profiling observations rests on the ability to conduct routine time and/or spatial series of profiles with multi-instrument systems that possess excellent time and depth resolution of all parameters. There are three primary components to this: 1) clean power to all instruments, 2) accurately time-resolved measurements, and 3) a routinely dependable deployment and recovery system. Our on-going ONR-supported research has permitted us to make advances in the timeresolution area, but we have serious needs in the two other areas. Our DURIP objectives are to: * purchase a Power Distribution System that can replace the obsolete MODAPS+ unit that we have been using since 1997. The objective is to provide clean power to multiple instruments (see below). * accurately measure the horizontal velocity field in front of the sinking profiler. We will meet that objective through the integration of a 600 kHz ADCP onto our profiling system. * enhance our fiber optic winch and cable system for deployment and recovery system.
