The program started in the late 1960's when Dr. Larry Harris arrived from the West Coast to spread his joy of the underwater world by taking his students on dives with him. In 1969 Ocean Engineering researcher Dr. Godfrey Savage became involved with Underwater 'Habitat' programs. As part of a UNH ocean projects course students and professors built a 'Habitat-Edalhab' to be used by scientists for underwater research.
The 70's saw a great deal of development in ocean exploration, and UNH kept pace by expanding its program to become a part of this exploration. In 1970 Al Waterfield became a NAUI Instructor and started teaching courses on campus. The first "Dive Safety Manual" was written in 1974 by Paul Lavoie, the first UNH Diving Safety Officer.
By the mid 1980's Paul oversaw the construction and use of a hyperbaric chamber, used as a DAN (Diving Alert Network) treatment facility as well as to enhance educational and research experiences. This chamber became a valuable tool for many years until its retirement to the Yucatan Peninsula.
In the 1990's UNH joined forces with other educational institutions involved in scientific diving and became an organizational member of the American Academy of Underwater Sciences (AAUS).
