Quick Summary

The submersible ALVIN descends underwater, surrounded by deep blue ocean, with a diver visible in the background. — Alvin The research submarine Alvin.

The Alvin is a deep-submergence research vehicle, also known as a submersible. It can carry a pilot and two scientific observers to depths of up to 4,000 meters. The Alvin's maneuverability has been crucial in discovering mineral deposits at mid-ocean seafloor spreading centers and previously unknown biological communities in those locations.1

The Alvin is operated by the Woods Hole Oceanographic Institution (WHOI), which is an independent international research and educational organization founded in 1930. WHOI supports hundreds of research projects, including studies of marine life, ocean chemistry, climate change, and seafloor geology. The institution has developed various exploration devices, including the Alvin, the remotely operated vehicle Jason, and the robotic submersible ABE.2

Robert Ballard
…early 1970s Ballard helped develop Alvin, a three-person submersible equipped with a mechanical arm. In 1973–75 he dived 9,000 feet (2,750 metres) in Alvin and in a French submersible to explore the Mid-Atlantic Ridge, an underwater mountain chain in the Atlantic Ocean. In 1977 and 1979 he was part of…
