These screen captures are from the new high-resolution 3D bathymetry model for the Great Barrier Reef and Coral Sea. Called Project 3DGBR, the digital elevation model (DEM) has a grid pixel size of 100 metres and the geographic area ranges from the tip of Cape York to northen New South Wales, then offshore almost to New Caledonia. Much of the source depth data for the project are provided by the Australian Hydrographic Service (AHS) using Royal Australian Navy (RAN) hydrographic survey data collected over many years. Other important source bathymetry data were obtained from Geoscience Australia (GA). The project partners gratefully acknowledge the assistance of the AHS, RAN and GA staff to the project.
