Seagrass Spotter is a free app, designed to encourage ocean enthusiasts around the world to become citizen scientists.

In just a few taps on a phone, users can help Project Seagrass better understand seagrass meadows in the local area so that their species type, distribution and health can be recorded and researched.

Seagrass Spotter was created by Project Seagrass, in association with Cardiff University and Swansea University.
