Citizen science

Turn every dive into ocean science

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

What scientists need, and how you help

  • More places

    Most ocean records come from a few coasts. Log every dive, even quiet sites.

  • What wasn't there

    Full dive logs show when a species goes missing. Log every animal, not just the highlights.

  • Same reefs, every year

    Change only shows up over years. Keep logging your home reef.

  • Names they can trust

    Lookalike species trip up records. Tag animals and add a photo.
