The public are being asked to record the sounds of the British seaside to help create a "sound map" of the country's coastline.
The scheme, organised by the National Trust, National Trust for Scotland and the British Library, allows people to upload up to five minutes of sound onto the online map, which they hope will capture sound from across the UK's 10,800-mile coastline.
The recordings will be used to create a new piece of music inspired by the coastline by Martyn Ware of Human League and Heaven 17.
Cheryl Tipp, curator of wildlife and environment sounds at the British Library, said:
Ms Tipp said the British Library already has a good collection coastal recordings, but "there are gaps" which the project hopes to identify and fill.
