DSV Alvin
RV "Atlantis II" is a research vessel formerly operated by Woods Hole Oceanographic Institution. The ship was built in 1962. She was used as the support vessel for the "Alvin" submersible for many years, and retired from Woods Hole service in 1996. After a period of inactivity in New Orleans she was transferred to the travel adventure company Outlander Expeditions in 2006. In 1986 she was used by Dr. Robert Ballard as mother-ship to "DSV Alvin" when Ballard and team surveyed the RMS Titanic wreck for the first time. The Titanic expedition was sponsored by National Geographic.
