The ocean covers 70% of the planet but is the least-recorded place on Earth. Scientists can't be on every reef. Divers are.

Most ocean records come from a few coasts. Log every dive, even quiet sites.
Full dive logs show when a species goes missing. Log every animal, not just the highlights.
Change only shows up over years. Keep logging your home reef.
Lookalike species trip up records. Tag animals and add a photo.
