Additionally, he was a crewmember on the NEEMO (NASA Extreme Environment Mission Operations) One, and Commander of the NEEMO eight multi-day underwater missions. He also served as a submersible pilot on the Pavilion Lake Expedition focused on exploring a deep water lake in western Canada where unusual life forms called microbiolites have very recently been discovered.
