Primary Products Introduction Overview Map—Depth to Pleistocene Bedrock Surface Overview Map—Reef and Sediment Thickness Overview Map—Benthic Ecosystems and Environments Overview Map—Sedimentary Grains in 1989 Overview Map—Summary Illustration Index Map Evolution Overview—Coral Ages and Shelf-Edge Models Introduction Seven Coral Reef Ecosystems Two Coral Reef Architectures Introduction: The excellent seismic data and abundance of radiometric dates on corals allowed construction of detailed cross-sectional models of four areas of the shelf margin. The models are discussed in Tile 1, Tile 6, and Tile 7/8 in the tile-by-tile analysis. In essence, the models show seven successive replications of two main coral reef architectures. continue to: Seven Coral Reef Ecosystems
