Human Occupied Vehicle (HOV) Alvin (a.k.a. DSV-2) — Woods Hole Oceanographic Institution (WHOI). On November 25, 2018, Alvin had completed 5,000 dives. Commissioned on June 5, 1964, it is owned by the U.S. Navy and operated by the Woods Hole Oceanographic Institution. Alvin is manned by a three-person crew of one pilot and two scientific observers. It is launched from the U.S. Navy deep submergence support vessel RV Atlantis (AGOR-25) and it has a maximum operating depth of 4,500 m (14,770 ft) for dives lasting up to 10 hours. Alvin’s most famous exploits include locating a hydrogen bomb in the Mediterranean Sea (1966), exploring deep-sea hydrothermal vents (1980s), and it conducted the first submersible dive on the wreck of the Titanic in 1986. Research conducted by scientists working aboard Alvin has been featured in approximately 2,000 science papers. Alvin was named to honour its main proponent, M. Allyn Vine.
