Distribution of mapped Halimeda bioherms - Great Barrier Reef

Distribution of mapped Halimeda bioherms in A) the Northern Great Barrier Reef province, and B) the Swain Reefs complex in the southern Great Barrier Reef. Bioherms were identified and boundaries delineated from high resolution multibeam and lidar bathymetry datasets from Project 3D-GBR (Beaman, 2010; Geoscience Australia) using method described by McNeil et al., (2016).
