Analysis of coral growth patterns and populations in Bermuda reveals that living coral abundance on the reefs of Castle Harbor, a location where extensive dredging occurred during 1941- 1943, is much reduced in comparison to external North-South reefs. Dead corals, sampled in the harbor, have skeletal patterns of growth which are similar and which show a marked decline in growth for several years prior to death. For the brain coral genus Diploria, both D. strigosa and D. labyrinthiformis are fairly evenly represented on contemporary North-South reefs and in the assemblages of dead corals from Castle Harbor, while D. labyrinthiformis, …
