That's about three years continuous recording. Though I assume it's
probably more like lots of sites for shorter periods.

Presumably just certain factors of the sound. Do you know if he's trying
for species recognition?
At least it's not preserved samples in bottles like it can be in
Oceanography. The ships are expensive to run, so must be continuously
used, so the sampling never stops. Those bottles require someone to sit
with a microscope and tweezers counting what's found.
