Alvin (DSV-2) is a 16 tonnes, manned deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI). The craft was built by General Mills, in Minneapolis, Minnesota. Named both for the famous cartoon chipmunk and the its proponent Allyn Vine , the Alvin was commissioned June 5, 1964 and retired from active operation in 2004 after 40 years of worldwide oceanographic research. The submersible is launched from the deep submergence support vessel Atlantis, which is also owned by the Navy and operated by WHOI. Alvin was designed as a replacement for bathyscaphes and other less maneuverable oceanographic vehicles. The three-person vessel allows for two scientists and one pilot to dive for up to eight hours at 4500 meters. The submersible features two robotic arms and can be fitted with mission-specific sampling and experimental gear.
Over the years, the Alvin has undergone many overhauls to improve its equipment and extend its lifetime. The most recent overhaul was during 2001; in which, among other equipment, motor controllers and computer systems were added.
On August 6, 2004, the National Science Foundation announced the creation of a new Human Occupied Vehicle (HOV) to replace the aging Alvin. The new vehicle is designed to dive deeper and use new scientific equipment. The fate of the Alvin when this new submersible arrives is unknown. Many say it will be either placed in a museum or be used to explore relatively shallow waters.
