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 andor 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.
