Sentry in the Gulf

Sentry on Patrol

In June 2010, aboard R/V Endeavor, WHOI engineers Al Duester (right) and Andy Billings (center)  helped recover the autonomous underwater vehicle (AUV) Sentry after a dive in the Gulf of Mexico. WHOI investigators, supported by the National Science Foundation, traveled to the Gulf to search for subsurface plumes of hydrocarbon-rich waters resulting from the Deepwater Horizon oil spill. Sentry, equipped with an instrument that measured chemicals in the water, was programmed to cross back and forth across the plume to map it.
