The new young tyke meets the old man of the sea, as Sentry meets Alvin during testing off Bermuda.

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.
Caption from Oceanus magazine, Vol. 45, No. 2, Pg. 7:
OLD MAN OF THE SEA MEETS YOUNG TYKE—Sporting a freshly painted red sail, the submersible Alvin returned this spring after six months of routine maintenance for the last series of missions in its 42-year career. It is scheduled to be replaced by a new deeper-diving sub in 2009. Off Bermuda, researchers from the WHOI Deep Submergence Laboratory also tested the newest member of WHOI’s deep-sea fleet, Sentry, for the first time in deep water. Sentry is a faster, more maneuverable, easier-to-operate “offspring” of WHOI’s pioneering deep-sea robotic vehicle, ABE (the Autonomous Benthic Explorer). In June, ABE became the first autonomous underwater vehicle appointed to the WHOI operated National Deep Submergence Facility, which provides deep-sea exploration vehicles for the national scientific community.
