Abstract

The ocean is a dynamic and complex system. Understanding it through observation is critical to predicting and adapting to it. This thesis details a new approach to making vertical profiles at a fixed geographic location. It describes the design of a novel autonomous moored underwater profiler to characterize the water column of the continental shelf. The theory supporting the design is detailed, and the results of laboratory and field tests are presented. The rationale for the system, sub-system, and component design and selection is supported through calculations, and/or validated through bench testing. The resulting prototype is a hybrid of a wire follower type profiler. The profiler is attached to a subsea mooring and it is capable of profiling the entire water column. Using a buoyancy engine and compound pulley system, the unique propulsion system only requires power for the ascent. Performance analysis of the prototype during open water field trials indicated a high potential for the profiler to operate as intended.
