An ambitious international project to map the seabed is calling on boaties with echo technology and GPS to help out.
A target was set to map the entire seabed by 2030 at a UN ocean conference in 2017.
Five years on and project Seabed 2030 is gathering pace, but needs volunteers.
Twenty-five percent of the ocean floor has been mapped so far - about the size of Europe.
To fully understand ocean currents and their effect on climate change, an adequate map is required.
Seabed 2030 aims to collate bathymetric data to produce a definitive map of our ocean floor by 2030, and make it available to anyone who's interested.
To help with the remaining many millions of square kilometers of seabed - about 270 million - calls are out for mariners to turn ocean mappers and become citizen scientists. Kathryn speaks with Jamie McMichael-Phillips from Seabed 2030.
