Investigator: John P. Crimaldi

Sponsor: Office of Naval Resarch

Program: Chemical Plume Tracing Progarm (Dr. Keith Ward)

Funding Dates: June, 2000 - May 2002

Objective: Analyze odor plume data to determine how spatial and temporal plume structure varies throughout a plume and across different flow conditions. This knowledge will aid in the development of efficient artificial sensors and search algorithms for autonomous plume-tracking robots.
