To understand coastal change and anticipate what our future coast will look like, scientists carry out regular field surveys in the form of beach profiles and digital elevation models (DEMs). Until now, accessible data has remained scarce, particularly for the shoreface (the subtidal extension of the beach), where it is more difficult to collect data. With a relatively sheltered position, Porsmilin beach in Brittany (France) has been the scene of numerous topo-bathymetric surveys, and the dataset has recently been made available.
