This paper reports an investigation into the problem of rapid identification a channel that crosses body water using one or more Unmanned Surface Vehicles (USV). A new algorithm called Proposal Based Adaptive Channel Search (PBACS) is presented as potential solution improves upon current methods. The empirical performance PBACS compared to lawnmower surveying and Markov decision process (MDP) p...

Abstract Ocean monitoring is an expensive and time consuming endeavor, but it can be made more efficient through the use of teams autonomous robots. In this paper, we present a system for identification tracking ocean fronts by coordinating sampling efforts heterogeneous team surface vehicles (ASVs) underwater (AUVs). The primary contributions study are (1) our algorithm performing coordination...
