(13677) Alvin Main-belt Asteroid
Discovered on 2 July 1997 by Spacewatch at Kitt Peak.
Alvin is a deep-sea submersible with a depth range of 4000 meters. Built in 1964, it was used for some of the greatest undersea adventures of all, including the recovery of a lost nuclear device, the mapping of the Mid-Ocean Ridge and the discovery of “black smoker chimneys” and associated tube worms.Naming citation (20030614/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
