Adaptive Oceanographic Sampling with Mobile Assets

Stephanie Petillo


Currently, most oceanographic sampling requires costly trips to sea to collect data sets using a variety of deployable instruments and/ or underwater vehicles.  Where an oceanographer chooses to look for certain hydrographic features is based on the oceanographer's personal knowledge of the structure and general location of said features in time and space.  This challenges ocean engineers to develop autonomy aboard AUVs such that adaptive environmental feature tracking and 
detection may occur in the dynamic ocean without an oceanographer's guidance.  This talk presents a number of tools and methods that are currently in use to begin the development of autonomous quantitative detection and tracking of hydrographic features onboard AUVs.  Results are presented for a basic thermocline tracking mission that has been evaluated both in simulation and in the water.
