Based on the Levenberg-Marquardt multivariate optimization procedure, the algorithm is developed for retrieving major water colour producing agents: chlorophyll-a, suspended minerals and dissolved organics. Two assurance units incorporated by the algorithm are intended to flag pixels with inaccurate atmospheric correction and specific hydro-optical properties not covered by the applied hydro-optical model. The hydro-optical model is a set of spectral cross-sections of absorption and backscattering of the colour producing agents. The combination of the optimization procedure and a replaceable hydro-optical model makes the developed algorithm not specific to a particular satellite sensor or a water body. The algorithm performance efficiency is amply illustrated for SeaWiFS, MODIS and MERIS images over a variety of water bodies.<\/jats:p>","DOI":"10.3390\/a2010470","type":"journal-article","created":{"date-parts":[[2009,3,10]],"date-time":"2009-03-10T15:26:00Z","timestamp":1236698760000},"page":"470-497","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Semi-empirical Algorithm for the Retrieval of Ecology-Relevant Water Constituents in Various Aquatic Environments"],"prefix":"10.3390","volume":"2","author":[{"given":"Anton  A.","family":"Korosov","sequence":"first","affiliation":[{"name":"Nansen International Environmental and Remote Sensing Centre \/ 14th line 7, St. Petersburg, Russia"},{"name":"Nansen Environmental and Remote Sensing Centre \/ Thormohlensgt. 47, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dmitry  V.","family":"Pozdnyakov","sequence":"additional","affiliation":[{"name":"Nansen International Environmental and Remote Sensing Centre \/ 14th line 7, St. Petersburg, Russia"},{"name":"Nansen Environmental and Remote Sensing Centre \/ Thormohlensgt. 47, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Are","family":"Folkestad","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Water Research \/ Gaustadalleen 21Oslo, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lasse  H.","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Nansen Environmental and Remote Sensing Centre \/ Thormohlensgt. 47, Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"S\u00f8rensen","sequence":"additional","affiliation":[{"name":"Norwegian Institute for Water Research \/ Gaustadalleen 21Oslo, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Shuchman","sequence":"additional","affiliation":[{"name":"Michigan Tech Research Institute \/ 3600 Green Court, Suite 100, Ann Arbor, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"709","DOI":"10.4319\/lo.1977.22.4.0709","article-title":"Analysis of variations in ocean colour","volume":"22","author":"Morel","year":"1977","journal-title":"Limnol.
