dc.description.abstractTURBIDITY IS A KEY INDICATOR OF WATER QUALITY. IT HAS BIOTIC EFFECTS DUE TO LOW PENETRATION OF LIGHT INTO THE WATER SUCH AS PHOTOSYNTHESIS REDUCTION. THE SEASONAL AND INTERANNUAL VARIABILITY OF TURBIDITY IN THE EASTERN TROPICAL PACIFIC COAST OF MEXICO WERE ANALYZED USING OCEAN COLOR DATA. THE REGION HAS AN EXTENDED CONTINENTAL SHELF, WITH SEVERAL RIVER DISCHARGES AND MARKED SEASONAL PATTERNS OF WIND. REMOTE SENSING DATA (1998 TO 2017) OF REFLECTANCE, WIND, RAINFALL, AND RIVER DISCHARGES WERE ANALYZED THROUGH HOVMÖLLER DIAGRAMS AND EMPIRICAL ORTHOGONAL FUNCTIONS. THE RESULTS INDICATED THAT WIND STRESS EXPLAINED 76% OF THE TURBIDITY VARIANCE, WHILE 8% WAS EXPLAINED BY RIVER DISCHARGES AND RAINFALL. IN WINTER, TURBIDITY IS INTENSIFIED BY RESUSPENSION MECHANISMS IN FRONT OF THE SOUTHERN RIVER MOUTHS. IN SPRING, TURBIDITY INCREASES DUE TO PHYTOPLANKTON PARTICULATE CONCENTRATIONS ENHANCED BY COASTAL UPWELLING. DURING SUMMER AND AUTUMN, WIND STRESS IS WEAKER AND RIVER DISCHARGES INCREASE, THUS TURBIDITY INCREASES IN FRONT OF NORTHERN RIVER MOUTHS. EL NIÑO-SOUTHERN OSCILLATION GENERATES TURBIDITY ANOMALIES BY ALTERATION OF RAINFALL AND WIND STRESS. DESPITE THE PROXIMITY OF THE RIVER MOUTHS, THE COASTAL WATER TURBIDITY IS EXPLAINED BY DIFFERENT PROCESSES, WHICH NEED TO BE ASSESSED IN COASTAL MANAGEMENT.
