Assessment of Coastal Water Quality by Testing a Linear Model Using Landsat8 sst Data:ExploratoryStudy

The Mediterranean Basin, off the coast of Tangier, Morocco, is one of the most valuable seas, because of the diversity of its ecosys-tem. However, pollution has become a growing issue along this coast recently. For this reason, we tested a linear model developed for the Atlantic western coastal waters of Tangier using sea surface temperature (sst) estimated from Landsat 8 images and Escherichia coli concentration (E. coli) in-situ measurement to deter-mine the Mediterranean northern coastal waters quality of Tang-ierin15SelectedSites(ss1 to ss15)alongthecoastfromTangier to Ksar-Sghir. In addition, descriptive statistics, and geographic information systems (gis) were employed to explore the spatial association of the data. The results indicate that the sst and E. coli distributions have the highest values in the ss4–ss13 and ss15 due to the Souani and Mghogha rivers and Tangier Med Port, reflecting poor quality and a very high level of dangerous contam-ination inthis area.The ss1, ss2, ...
