This page summarizes a few of the outcomes of the ONR and DARPA supporter Chemical Plume Tracing (CPT) project. This project successfully demonstrated an autonomous underwater vehicle, operating in the Atlantic ocean in the near-shore environment off Duck, NC, tracking a chemical plume for 975 m from a first point-of-contact to its source and declaring the source location with an accuracy of 13 meters.

======= Plume simulation resulting from this project =================================
The EFM article above presents a dynamic model suitable for generating realistic chemical sensor readings for an AUV traveling in the vicinity of a chemical plume generated by release of a chemical in a turbulent flow field. The windows source and executable are contained in a zip file downloadable via the following link.

Zipped Simulation.
