The science of autonomy is the systematic development of funda­mental knowledge about autonomous decision making and task completing in the form of testable autonomous methods, models, and systems. Marine autonomy applications are rapidly growing, both in numbers and in complexity. For systematic advances, we integrate varied disciplines and provide fundamental results in minimum-time path planning, energy-optimal path planning, and optimal adaptive sampling based on mutual information fields, all in complex dynamic flows. The aim is to set a theoretical basis for a large number of vehicles forming heterogeneous and collabora­tive underwater swarms that are smart, i.e. knowledgeable about the predicted environment and their uncertainties, and about the predicted effects of autonomous sensing on future operations. Results are thus extended to coordinated groups of vehicles that maintain swarm formations and avoid dynamic obstacles, and to three-dimensional paths, anisotropic motion constraints, onboard adaptive routing, and path planning under uncertainty. Examples are provided for varied nonlinear fluid and ocean conditions. We also highlight some of our recent related results, including: Bayes­ian nonlinear data assimilation and inference of model equations; multiresolution high-order modeling; multiscale ocean dynamics; and, stochastic Lagrangian Coherent Structures.

Recent results from the MSEAS group on the multiscale interactions of internal tides in the Middle Atlantic Bight and Shelfbreak front regions were featured on MIT front page on Sept 28, 2016. The article is entitled “Researchers find explanation for interacting giant, hidden ocean waves” and can be accessed here. The relevant papers “Internal-tide Interactions with the Gulf Stream and Middle Atlantic Bight Shelfbreak Front” published in JGR Oceans can be accessed here and the paper “A Coupled-mode Shallow Water model for tidal analysis: Internal-tide reflection and refraction by the Gulf Stream” published in JPO can be accessed here.
