A high spatial and temporal resolution monitoring program has been conducted in Sisal beach starting on Spring 2015. Weekly to bi-weekly beach profiles are conducted along 20 transects located between the east jetty of the Sisal Port and the Sisal Pier. This data set is used to investigate seasonal changes. The goal is to continue such program in order to generate a novel dataset that will allow us to investigate interannual variability in this region. The morphological changes can be correlated with the different forcing variables obtained in the Coastal Observatory to understand long-term beach morphology evolution.
