Total suspended matter (TSM) concentrations were derived from ocean colour imagery (MERIS data) in Minas Basin. Analysis of time series of TSM in 1-km2 pixel boxes throughout the Basin revealed an annual cycle in TSM in most parts of the Basin. Higher TSM of up to 85 g/m3 was observed in late-winter (February - March), and lower TSM of 5-10 g/m3 characterized late-summer (July - August). The largest annual variation occurred in the centre of Basin, and the smallest variation occurred in shallow areas. Satellite-derived TSM were compared to predictions using the Delft3D model. Increasing model erosion rate in winter relative to summer was necessary to improve agreement between model and satellite-derived TSM. In comparison with the satellite-derived estimates, the model underestimated TSM in shallow areas in summer and overestimated it in winter. This discrepancy is likely due to inaccurate satellite-derived TSM in shallow, high concentration areas of the Basin.
