In this study, we used remotely sensed reflectances in the red and blue-green portions of the visible spectrum retrieved from Medium Resolution Imaging Spectrometer (MERIS) and the International Space Station (ISS) Hyperspectral Imager for the Coastal Ocean (HICO) images to create a model to estimate CDOM absorption. CDOM absorption results were then used to develop an algorithm to predict the surface salinities of coastal bays and estuaries in New England, Middle Atlantic, and Gulf of Mexico regions. Algorithm-derived CDOM absorptions and salinities were successfully validated using laboratory measured absorption values over magnitudes of ~0.1 to 7.0 m\u22121 and field collected CTD data from oligohaline to polyhaline (S less than 5 to 18\u201330) environments in Narragansett Bay (Rhode Island); the Neuse River Estuary (North Carolina); Pensacola Bay (Florida); Choctawhatchee Bay (Florida); St. Andrews Bay (Florida); St. Joseph Bay (Florida); and inner continental shelf waters of the Gulf of Mexico.<\/jats:p>","DOI":"10.3390\/rs8040283","type":"journal-article","created":{"date-parts":[[2016,3,29]],"date-time":"2016-03-29T16:00:28Z","timestamp":1459267228000},"page":"283","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Optical Models for Remote Sensing of Colored Dissolved Organic Matter Absorption and Salinity in New England, Middle Atlantic and Gulf Coast Estuaries USA"],"prefix":"10.3390","volume":"8","author":[{"given":"Darryl","family":"Keith","sequence":"first","affiliation":[{"name":"National Health and Environmental Effects Research Laboratory, Office of Research and Development, U.S. Environmental Protection Agency, Atlantic Ecology Division, Narragansett, RI 02882, USA"}]},{"given":"Ross","family":"Lunetta","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, Office of Research and Development, U.S. Environmental Protection Agency, Environmental Measurements and Methods Division, Research Triangle Park, Durham, NC 27709, USA"}]},{"given":"Blake","family":"Schaeffer","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, Office of Research and Development, U.S. Environmental Protection Agency, Environmental Measurements and Methods Division, Research Triangle Park, Durham, NC 27709, USA"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5110","DOI":"10.1016\/j.watres.2011.07.014","article-title":"Characterizing chromophoric dissolved organic matter in Lake Tianmuhu and its catchment basin using excitation-emission matrix fluorescence and parallel factor analysis","volume":"45","author":"Zhang","year":"2011","journal-title":"Water Res."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"75","DOI":"10.1016\/j.marchem.2004.03.011","article-title":"Mercury and methylmercury in Hudson River sediment: Impact of tidal resuspension and methylation","volume":"90","author":"Heyes","year":"2004","journal-title":"Mar.
