The Adaptive Sampling and Prediction (ASAP)

Program

A multi-disciplinary University research initiative sponsored by the United States Department of Defense.

ASAP Overall Goal

Learn how to deploy, direct, and utilize autonomous vehicles and other mobile sensor platforms most efficiently to sample the ocean, assimilate the data into numerical models in real or near-real time, and predict future conditions with minimal error.

The Players

• Princeton University– Control Theory, Adaptive Sampling

• Naval Postgraduate School– Manned and Unmanned Aircraft, Real-Time Bottom Moorings

• Harvard University– Numerical Modeling and Prediction

• Massachusetts Institute of Technology– Odyssey AUVs, Acoustic Data Assimilation (ADA)

• Woods Hole Oceanographic Institution– Shallow Water Gliders

• Scripps Institution of Oceanography– Deep Water Gliders

• California Institute of Technology– Lagrangian Coherent Structures

• National Research Council (Canada)– Vehicle Control, Adaptive Sampling

Adaptive Sampling Ingredients

Mobile sensor platforms (vehicles): • Underwater gliders (SIO=4, WHOI=5, Canada=?) • Propeller-driven AUVs (MIT=2, NPS=2, MBARI=1?, CalPoly=?)• Research aircraft (NPS)• Ships

Quantitative sampling metrics:

• Maximize broad-area coverage (minimize OA error) • Maximize sampling of significant dynamics (eg, via feature tracking)• Minimize model uncertainty

Combining the Ingredients: Strawman Allocation

Simple approach to heterogeneous fleet: • Associate each kind of vehicle with a metric (or possibly two).• Make association so that vehicle capabilities are good match with scales

addressed by metric.

1. Maximize broad-area coverage • Underwater gliders• Airplanes

2. Maximize sampling of significant dynamics• Propeller-driven vehicles• Ships

3. Minimize model uncertainty• Propeller-driven vehicles• Ships• Others?

Unifying Science Goal:

Construct a volume and heat budget for the three-dimensional upwelling center off Point Ano Nuevo during upwelling, relaxationand transition events.
