With 35 years of diving experience, Terrence N. Tysall is one of the underwater world’s most accomplished explorers. From the deep WWII wrecks of the South Pacific, to the submerged caves of Yucatan, Belize, and Bermuda, to the historic wreck of USS Monitor, to the lava tubes of the Canary Islands, Terrence has dived some of the planet’s most remote waters gathering data about what lies at the bottom and beyond.

Terrence has led multiple scientific/research expeditions around the world, including the first SCUBA exploratory dives on the SS Edmund Fitzgerald in Lake Superior, the USS Atlanta off of Guadalcanal in the Solomon Islands, and the first cave exploration and geologic sampling conducted at the bottom of the Great Blue Hole of Belize.

Terrence is currently completing his masters degree in subaquatic biospeleology from Texas A&M University-Galveston. Terrence has earned instructor trainer ratings from ANDI, IANTD, NAUI, NSSCDS, NACD, SSI, and TDI. In addition to these certifications, Terrence serves on a variety of technical advisory boards for NOAA and other scientific research agencies both in the United States and abroad.
