"Reef growth and carbonate sedimentation at the southernmost Pacific re" by Colin D. Woodroffe, Michelle Linklater et al.
Lord Howe Island and Balls Pyramid are located at the latitudinal limit of coral reef formation in the Tasman Sea, with the fringing reef on the western margin of Lord Howe Island considered to be the southernmost coral reef in the Pacific. An extensive submerged fossil reef occurs on the shelf around Lord Howe Island. Mapping of the shelf surrounding Balls Pyramid, 24 km south of Lord Howe Island, has revealed a comparable submerged mesophotic reef system in 30–50 m water depth supporting scattered live coral colonies. Radiocarbon dating of coral extracted from limestone cores on the fossil...
