The deep-sea exploration vehicle Alvin has had a fascinating and storied history. Since its launch in 1964, the three-person research vessel has made more than 4,000 dives to the seafloor, to depths of almost three miles. Alvin has discovered strange organisms, sampled the hydrothermal vents where the earth's crust splits open and even documented the wreckage of the Titanic. Here are some highlights from Alvin's many adventures.
