Definitions, concepts, and\r\nprogress towards answering these questions using quantitative predictions and fundamental\r\nprinciples are presented. Results in reachability and path planning, adaptive sampling,\r\nmachine learning, and teaming machines with scientists are overviewed. The integrated\r\nuse of differential equations and theory from varied disciplines is emphasized. The results\r\nprovide an inference engine and knowledge base for expert autonomous observing systems.\r\nThey are showcased using a set of recent at-sea campaigns and realistic simulations.\r\nReal-time experiments with identical AUVs in the Buzzards Bay and Vineyard Sound region\r\nfirst show that our predicted time-optimal paths were faster than shortest distance\r\npaths. Deterministic and probabilistic reachability and path forecasts issued and validated\r\nfor gliders and floats in the northern Arabian Sea are then presented. Novel Bayesian adaptive\r\nsampling for hypothesis testing and optimal learning are finally shown to forecast the\r\nobservations most informative to estimate the accuracy of model formulations, the values\r\nof ecosystem parameters and dynamic fields, and the presence of Lagrangian Coherent\r\nStructures.","protected":false},"excerpt":{"rendered":"<p>Ocean scientists have dreamed and recently started to realize an ocean observing revolution with autonomous observing platforms and sensors.
