January 7, 2008Engineer Rod Catanach steadies the Sentry autonomous underwater vehicle as it is lowered for tests off the WHOI dock in November 2007. Sentry is a robot built for exploring the deep ocean; it will often be used to complement Alvin by surveying large swaths of ocean floor to determine the best spots for close-up exploration. The AUV is slated to join the National Deep Submergence Facility in 2008. (Photo by Tom Kleindinst, Woods Hole Oceanographic Institution)
