Description:The decline in living coral since the 1970s has conspicuously slowed reef construction on a global scale, but the related process of reef erosion is less visible and not often quanti fied. Here, we present new data on the constructional and deconstructional sides of the carbonate-budget equation in the Florida Keys, U.S.A. We documented Orbicella spp. calcification rates at four offshore reefs and quanti fied decadal-scale rates of Orbicella -reef erosion at a mid-shore patch reef. Using Orbicella coral heads fitted with permanent markers in 1998, we measured reef-elevation loss at 28 stations over 17.3 yr to estimate a mean erosion rate of −5.5 (/C63.2, SD) mm yr−1. This loss equates to an erosion rate of
