Full description

Sediment derived from the decomposition of Halimeda algae is a major contributor to the tropical back-reef carbonate depositions. Halimeda bioherms occur extensively on the northern Great Barrier Reef (GBR), Australia. This dataset represents the most complete, high-resolution spatial mapping of the extent of northern GBR Halimeda bioherms, based on airborne lidar and multibeam echosounder bathymetry data. Three distinct morphological sub-types are described: reticulate, annulate, and undulate. The northern GBR bioherms cover an area of 6095 km2, three times larger than previous estimates.

Lineage

Statement: To accurately map the total areal extent and redefine the geomorphology of the GBR bioherms, this study synthesised a range of information derived from new airborne lidar and multibeam bathymetry datasets, seismic profiling data, and combining these with existing sediment sampling surveys, seismic profiles, and vibracores taken from the published literature. Comparisons were made between the previously reported Halimeda bioherm spatial extent, distribution, and morphology descriptions, and our analysis of the new and existing data. See https://doi.org/10.1007/s00338-016-1492-2 for full methodology.
