This study investigated the impact of mineral turbidity on line-height algorithms using MCI as a primary example. Inherent optical properties from two turbid eutrophic lakes were used to simulate reflectance spectra. The simulated results: (1) confirmed a non-linear relationship between Chl-a and MCI; (2) suggested optimal use of the MCI at Chl-a &lt; ~100 mg\/m3 and saturation of the index at Chl-a ~300 mg\/m3; (3) suggested significant variability in the MCI:Chl-a relationship due to mineral scattering, resulting in an RMSE in predicted Chl-a of ~23 mg\/m3; and (4) revealed elevated Chl a retrievals and potential false positive algal bloom reports for sediment concentrations &gt; 20 g\/m3. A novel approach combining both MCI and its baseline slope, MCIslope reduced the RMSE to ~5 mg\/m3. A quality flag based on MCIslope was proposed to mask erroneously high Chl-a retrievals and reduce the risk of false positive bloom reports in highly turbid waters. Observations suggest the approach may be valuable for all line-height-based Chl-a algorithms.<\/jats:p>","DOI":"10.3390\/rs11192306","type":"journal-article","created":{"date-parts":[[2019,10,4]],"date-time":"2019-10-04T04:12:52Z","timestamp":1570162372000},"page":"2306","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["The Effect of Mineral Sediments on Satellite Chlorophyll-a Retrievals from Line-Height Algorithms Using Red and Near-Infrared Bands"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0198-5617","authenticated-orcid":false,"given":"Chuiqing","family":"Zeng","sequence":"first","affiliation":[{"name":"Water Science and Technology Directorate, Environment and Climate Change Canada, 867 Lakeshore Rd, Burlington, ON L7S 1A1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caren","family":"Binding","sequence":"additional","affiliation":[{"name":"Water Science and Technology Directorate, Environment and Climate Change Canada, 867 Lakeshore Rd, Burlington, ON L7S 1A1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1016\/j.jglr.2018.04.001","article-title":"An analysis of satellite-derived chlorophyll and algal bloom indices on Lake Winnipeg","volume":"44","author":"Binding","year":"2018","journal-title":"J.
