In addition to the SPOT4 (Take5) dataset, we used several Landsat5, 7, 8 images to document the variations in suspended particulate matter (SPM) concentration in the turbid Gironde and Loire estuaries (France). Satellite-derived SPM concentration was validated using automated in situ turbidity measurements from two monitoring networks. The combination of a multi-temporal atmospheric correction method with a near-infrared to visible reflectance band ratio made it possible to quantify SPM surface concentration in moderately to extremely turbid waters (38\u20134320 g\u00b7m\u22123), at an accuracy sufficient to detect the maximum turbidity zone (MTZ) in both estuaries. Such a multi-sensor approach can be applied to high spatial resolution satellite archives and to the new ESA Sentinel-2 mission. It offers a promising framework to study the response of estuarine ecosystems to global changes at unprecedented spatio-temporal resolution.<\/jats:p>","DOI":"10.3390\/rs70809507","type":"journal-article","created":{"date-parts":[[2015,7,24]],"date-time":"2015-07-24T10:44:26Z","timestamp":1437734666000},"page":"9507-9528","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["Toward Sentinel-2 High Resolution Remote Sensing of Suspended Particulate Matter in Very Turbid Waters:  SPOT4 (Take5) Experiment in the Loire and Gironde Estuaries"],"prefix":"10.3390","volume":"7","author":[{"given":"Pierre","family":"Gernez","sequence":"first","affiliation":[{"name":"EA 2160 Mer Mol\u00e9cules Sant\u00e9 (MMS), Universit\u00e9 de Nantes, 2 chemin de la Houssini\u00e8re,  44322 Nantes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Virginie","family":"Lafon","sequence":"additional","affiliation":[{"name":"GEO-Transfert, UMR 5805 Environnements et Pal\u00e9o-environnements Oc\u00e9aniques et Continentaux (EPOC), Universit\u00e9 de Bordeaux, All\u00e9e Geoffroy Saint-Hilaire, 33615 Pessac, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Astrid","family":"Lerouxel","sequence":"additional","affiliation":[{"name":"EA 2160 Mer Mol\u00e9cules Sant\u00e9 (MMS), Universit\u00e9 de Nantes, 2 chemin de la Houssini\u00e8re,  44322 Nantes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C\u00e9cile","family":"Curti","sequence":"additional","affiliation":[{"name":"SEA, Bordeaux Technowest, 25 rue Marcel Issartier, 33700 M\u00e9rignac, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6924-882X","authenticated-orcid":false,"given":"Bertrand","family":"Lubac","sequence":"additional","affiliation":[{"name":"UMR 5805 Environnements et Pal\u00e9o-environnements Oc\u00e9aniques et Continentaux (EPOC), Universit\u00e9 de Bordeaux, All\u00e9e Geoffroy Saint-Hilaire, 33615 Pessac, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvain","family":"Cerisier","sequence":"additional","affiliation":[{"name":"Groupement d'int\u00e9r\u00eat public (GIP) Loire Estuaire, 22 rue de la Tour d'Auvergne, 44200 Nantes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurent","family":"Barill\u00e9","sequence":"additional","affiliation":[{"name":"EA 2160 Mer Mol\u00e9cules Sant\u00e9 (MMS), Universit\u00e9 de Nantes, 2 chemin de la Houssini\u00e8re,  44322 Nantes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1016\/0025-3227(81)90046-3","article-title":"Suspended-sediment transport in the Seine estuary, France: Effect of man-made modifications on estuary\u2014Shelf sedimentology","volume":"40","author":"Avoine","year":"1981","journal-title":"Mar.
