| Abstract: | Two transects were drilled across the major ecologic zones of the c. 750 by 200 m reef, whose accumulation was controlled by a local Pleistocene topographic feature. The Reef is composed of 5 major ecologic zones: 1) a deep seaward rubble zone, 6-8 m depth; 2) a poorly developed spur and groove zone composed of massive head corals and Millepora (4-6 m water depth); 3) a characteristic high-energy oriented Acropora palmata zone extending from the surface down to 4 m; 4) a distinct broad reef flat composed of in situ A. palmata and coral rubble, followed by 5) a narrow low- energy back-reef zone of unoriented A. palmata, thickets of A. cervicornis, and various massive head corals in water 0-3 m deep. An extensive grass-covered carbonate sand flat 3-4 m deep extends in a landward direction from zone 5. - from Author |
