My job then did not require diving. It was Woods Hole Oceanographic Institution; they were serious about diving, and required AAUS and considerable training to dive as part of one's work. Post certification, I did evolve some of my work to include diving.
Oh, you were at WHOI? Wow, that's great. I knew the DSO at WHOI in the 80's, Teri Rioux, very well and we dove at WHOI way back then. I think Teri retired long time ago.
I was trained as an instructor at the URI GSO and was staff in their instructor training programs and ran other training programs with them way back then, late 80's and all through the 90's.
