There was one odd detail in David Lewis' book that I never completely understood. The biolumenescence from surf makes sense, but he spoke about another biolumenescence that occurred far out to sea. The Polynesian term for it was "ti lapa", and roughly translates to "underwater lightning", where on overcast nights, they observed flashes underwater that pointed to islands quite distant. I never understood what phenomenon this might be. I even spoke with a guy who specialized in fast-time response bioluminescent chemicals and he didn't have any good idea.
David interviewed enough people to convince me it was a real effect, but I confess that I don't know its origin and can't explain it.

Welcome John,
What I find most interesting about Polynesian navigation was how
they observed the directional bioluminescent pulses of pounding island
surf as a homing beacon. This is quite a clever way to use nature to
advantage.
