Suspended Solids in the Gulf of Urabá Colombia – Annual Average Estimation using MODIS MYD09Q1 Images

The paper presents the construction of an empirical model, applied to MODIS MYD09Q1 Images, based on in-situ samples of the Total Suspended Solids (TSS) found in the Gulf of Urabá (Colombia) in the period 2011 – 2015. The study highlights the usefulness of digital image processing when retrieving color data from the oceans, such as sedimentation. The resulting data proves to be relevant for the analyses of environmental care and ecological preservation in such coastal areas, which are known to be important due to their biodiversity but not as known regarding their associated sediment dynamics and concentration. Both spatial and temporal variability of sediments are analyzed in yearly scales. The results show significant season-driven differences in terms of concentration and direction of sediment plumes. It was found that annual average values exceed 100mg/L at El Rotico Bay due to the contributions from Atrato River at Boca del Roto within the Gulf of Urabá.
