Ask the Data

Ask the atlas a question

Answered strictly from this site's own structured data — destinations, sites, species, seasons, wrecks — with links to the pages behind every answer. If the atlas doesn't know, it says so.

Worked examples

These are real answers of the kind the assistant gives, rendered here so you can see the format before asking.

Example Where can I see whale sharks in February? The atlas cross-references whale-shark sightings marked reliable for February and returns those destinations with their likelihood labels and links — typically a handful of places, not a padded list.
Example How deep is the Thistlegorm? Structured wreck fields answer directly — depth to the deck, maximum depth on the seabed, and the recommended certification — with a link to the full wreck page.

Rate-limited per visitor. Never a substitute for training, briefings or medical advice — and it will tell you exactly that if you ask for any of those.
