Short summary
A coastal ridge on Anegada was surveyed in 2013 and 2015 to document short-term changes in morphology and weathering. Minor storms changed the ridge morphology and added new clasts to the lower parts. Observations imply that the ridge was initially emplaced during a more severe event; minor storms are only able to modify preexisting ridges. Second, bioweathering is a rapid process in tropical settings, as proven by the fact that white coral clasts in 2013 already depicted a grey patina in 2015.
