This picture is from Cromer. My eye was caught by the patterns of the rusty girders and the gently lapping water.
I wasn’t really expecting it to be used by the British Library in work for children about the sense of sound.
This recording was taken by Peter Toll beneath the surface at Norfolk’s Cromer pier. At a depth of six metres, the hydrophone picks up stones being dragged onto the beach by waves, as well as the metallic sounds from the creaking pier.
