An app and a camera phone are all that’s needed at more than 200 spots to help researchers monitor coastal areas

The CoastSnap project started in Australia in 2017 and has spread to beaches worldwide. You may have spotted the setup while out walking along the coast: a cradle to rest your phone on while taking a picture and a sign explaining where to send the snap.
