The five beaches are (from north to south): Pensarn; Morfa Dinlle; Borth; Amroth; Leys Beach (Aberthaw). Particle size information was collected using digital grain size analysis. Both an excel file containing the particle size analysis, images of grain size histograms and the raw digital data are provided. The data was collected to enable assessment of suitable quarry sources of shingle for beach renourishment.
