The goal of this project was to explore the design and deployment of a deep ocean delivery system to the seafloor. The overall system configuration included a cylindrical shell, a hemisphere nose cone, pressure tolerant batteries, and a pressure vessel to the house the electronics. As part of the design specifications, the system was to land within a 100 meter target radius directly below the location where the system entered the water. An approach was developed to determine the horizontal displacement for a given current profile and the system's interactions with the seafloor. The horizontal displacement was investigated for a variety of current profiles from the World Ocean Circulation Experiment. The influence of the center of gravity location, fins, and a drogue were examined by testing a small scale model in the UNH engineering tank and a large scale model in field experiments.
