Milestones

Meet Alvin

Alvin is the nation's only human-occupied deep-sea research submersible. It is owned by the U.S. Navy and operated by Woods Hole Oceanographic Institution for the national oceanographic community and was commissioned in 1964. Since then, Alvin has made more than 4,900 dives and has enabled dozens of new discoveries and countless insights into the way the ocean and our planet work.

Fun Facts

The excitement of seeing a small portion of the Earth never seen before, or possibly ever again, keeps me looking forward to my next day at the bottom of the sea.

— Dudley Foster, Alvin Pilot (1974-2006)
