Grecian Rocks time series

At left: An image of Grecian Rocks in 1971 shows a star coral surrounded by staghorn corals. The staghorn grew at a rapid rate in the decade preceding this photograph. Center: Staghorn began dying at the reef site in 1979, and by 1988 most staghorn at Grecian Rocks was severely eroded or dead. At right: By 2001, staghorn had been replaced by sea fans and sea whips, while the star coral (same star coral shown in 1971 and 1988 photographs) had become misshapen.
