Figure 121. Well site D/E-1 (from Dustan et al., 1991). (A) Submerged cement bags. Note fish, including large red grouper, encrusting stinging coral (Millepora spp.), and large anemone in foreground. Golf ball-size pea gravel under cement bags is visible in right foreground. (B) Closeup of cement bags shows encrusting Millepora spp. (to left) and colony of coral Oculina diffusa (center). Small fish are predominantly wrasses and juvenile grunts. (C) Fleshy macroalgae (Laurencia spp.) cover pea gravel surrounding cement bags. Pre-1983 sea urchin (Diadema antillarum) die-off photos showed area then was relatively barren of algae. Ten-cm-long handle near center is for scale. (D) Syringodium spp. and Thalassia spp. seagrass community as seen along radial-transect line away from cement-bag pile. Substratum was mostly natural sediment with an admixture of pea gravel. Community distribution is shown in Figure 120A.
