Alvin (DSV-2) is a manned deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel R/V Atlantis (AGOR-25), which is also owned by the U.S. Navy and operated by WHOI. The submersible has made over 4,400 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures and move about in total darkness. Research conducted by Alvin has been featured in nearly 2,000 scientific papers.
There is a small chance I can go diving with Alvin for my graduate research on hydrothermal vents. Fingers crossed!
