scientists are making exciting discoveries about the ocean
floor, thanks to deep-sea submersibles such as Alvin. Operated
by the Woods Hole Oceanographic Institution in Woods Hole,
Massachusetts, this three-person sub made its first dive
in 1964. Since then, Alvin has made more than 4,000
dives to an average depth of 2,079 meters
conducted a wide variety of research missions, from discovering
giant tubeworms on the Pacific Ocean floor near the Galápagos
Islands, to exploring the wreck of HMS Titanic in
the Atlantic Ocean.
met some amazing life on its travels, but so far it has not
encountered one of the deep sea's most mysterious inhabitants the
elusive giant squid. However, Alvin once was attacked
by a swordfish, which became trapped between two pieces of
the sub's fiberglass skin. The fish was brought back to the
surface and cooked for dinner!
Plans now are under way for a new Alvin. The new sub, slated for completion in 2008, will reach more
than 99% of the seafloor, diving to depths of 6,500 meters
