This data release contains time-series photographs taken of corals and coral habitats in the Florida Keys between 1959 and 2015 at Carysfort Reef and Grecian Rocks (a total of six sites). The original intent was to show coral reef recovery after Hurricane Donna devastated the area in 1960. Corals, especially elkhorn and staghorn coral, grew prolifically after the storm until the late 1970s, then began to decline, with the maximum period of decline centered around 1983 and 1984. These time-series photographs, showing the same individual coral colonies year after year, document the decline in coral health observed at these locations, mirroring patterns seen region-wide across the western Atlantic. A selection of the photographs was previously published (in low resolution) in Lidz and others (2006), wherein findings and conclusions related to these data were discussed. Lidz, B. H., Reich, C.
