Since then, DSV Alvin has been repeatedly overhauled and upgraded, keeping pace with current technology in countless dives and endless missions carrying humans into the deep blue sea.AdvertisementTop image: Even octopus love Alvin. Or is that murderous rage? 2008.Forging the original Alvin sphere in 1964.AdvertisementIn 1962, the Woods Hole Oceanographic Institute (WHOI) contracted with General Mills, makers of Cheerios, to build a research submarine. For $498,500, General Mills built a submersible capable of diving to 1,829 feet while keeping its humans alive. Soon, the submersible earned its name: Alvin, in honour of Allyn Vine, a WHOI scientist who got the idea started at a conference in 1956. Alvin was officially commissioned on June 5th, 1964, and made a test dive in the Woods Hole Harbor weeks later on June 26th. The following year, Alvin and the improvised catamaran Lulu continued testing, ranging the Bahamas, inspecting a listening array in the Tongue of the Ocean, and diving deeper and deeper in longer and longer dives to obtain Navy certification. Ever since then, it's been on one series of adventures after another.
