We map what the sunlight never reaches.

A small vessel, a small footprint, on purpose.

Fathom began in 2017 with one converted trawler and a conviction that deep-sea research didn't need a navy-scale budget to be rigorous. We still run a single vessel.

Every dive is logged publicly — depth, findings, and the ones that came back with nothing. Null results are still results, and we don't bury them to keep a clean record.

• Single research vessel, rotating six-person watch crew
• Every finding — including null results — published within 90 days
• No commercial sponsor holds rights to any discovery
