It's a bit of an inside joke. I was diving with Chris Newbert one day and he did a dive briefing and started to use the word crepuscular. Ofcourse we were all 'no way thats a real word', but he was right

And it sortof stuck

Oh, come on guys!! Obviously you all aren't jazz fans or you would have known Thelonious Monk's well-known piece, "Crepuscule With Nellie"; written in the late 1940s for his wife.
I also heard Lisa (formerly of Dive Makai) use the term "crepuscular dive", so maybe Chris got it from Lisa or Lisa from Chris, or both of them from way-cool Thelonious!!
