Young Tyke Meets the Old Man of the Sea

January 15, 2007

The new Sentry autonomous underwater vehicle meets the submersible Alvin during a testing expedition off Bermuda in April 2006. Sentry is a robotic underwater vehicle used 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.  Sentry is slated to join the National Deep Submergence Facility in 2008.
