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 time-resolution area, but we have serious needs in the two other areas.
