Underwater view of macroalgae surrounding a reef-building coral (Platygyra, center), 3 m depth, east of Marbat, site 32 (Fig. 7), 6 October 1982. were present including species from the genera Acropora (40 cm diameter tables), Astreopora (80 cm diameter), Pontes (35 cm high massive colonies), Favites (50-60 cm, longest dimension), and Turbinaria (75 cm diameter). Stylophora pistillata was common, but Pocillopora was rarely seen. The water conditions and shallow marine community composition near Sadh (sites 35-39) were similar to those at Marbat. Quantitative sampling of the epibenthos to 11 m depth (sites 35 and 39) revealed primarily macroalgal communities. At site 35, Ulva was the predominant alga with occasional Sargassum plants also present. Both crustose and articulate coralline algae were often present under the macroalgal canopy. Corals (Acropora and Stylophora) occurred only between 8 and 11m depth. Sargassum spp. were the most abundant macroalgae at site 39. Corals were more common below 5 m with Acropora, Favites and Cyphastrea present to 11 m Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smithsonian Institution.
