Here we present S2Shores (Satellite to Shores), the first sub-kilometer global atlas of coastal bathymetry based on depth inversion from wave kinematics captured by the Sentinel-2 constellation. The methodology reveals coastal seafloors up to a hundred meters in depth which allows covering most continental shelves and represents 4.9 million km2 along the world coastline. Although the vertical accuracy (RMSE 6\u20139 m) is currently coarser than that of traditional surveying techniques, S2Shores is of particular interest to countries that do not have the means to carry out in situ surveys and to unexplored regions such as polar areas. S2Shores is a major step forward in mitigating the effects of global changes on coastal communities and ecosystems by providing scientists, engineers, and policy makers with new science-based decision tools.<\/jats:p>","DOI":"10.3390\/rs13224628","type":"journal-article","created":{"date-parts":[[2021,11,17]],"date-time":"2021-11-17T09:16:11Z","timestamp":1637140571000},"page":"4628","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Global Satellite-Based Coastal Bathymetry from Waves"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5842-658X","authenticated-orcid":false,"given":"Rafael","family":"Almar","sequence":"first","affiliation":[{"name":"Laboratoire d\u2019Etudes en G\u00e9ophysique et Oc\u00e9anographie Spatiales (LEGOS), Universit\u00e9 de Toulouse\/CNRS\/CNES\/IRD, 31400 Toulouse, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7638-1108","authenticated-orcid":false,"given":"Erwin W.
