Abstract

This paper presents a behavior-based Adaptive Mission Planner (AMP) to trace a chemical plume to

its source and reliably declare the source location. The proposed AMP is implemented on a REMUS

Autonomous Underwater Vehicle (AUV) equipped with multiple types of sensors measuring:

chemical concentration, the flow velocity vector, and AUV position, depth, altitude, attitude and

speed. This article describes the methods and results from experiments conducted in November

2002 at San Clemente Island, California using a plume of Rhodamine dye developed in a turbulent

fluid flow (i.e., near shore ocean conditions). These experiments demonstrated chemical plume

tracing over 100 meters and source declaration accuracy relative to the nominal source location on

the order of tens of meters.
