The Australian Bathymetry and Topography (AusBathyTopo) Torres Strait dataset contains depth and elevation data compiled from all available data within the Torres Strait into a 30 m-resolution Digital Elevation Model (DEM). The Torres Strait lies at the northern end of the Great Barrier Reef (GBR), the largest coral reef ecosystem on Earth, and straddles the Arafura Sea to the west and the Coral Sea to the east. The Torres Strait area is bounded by Australia, Indonesia and Papua New Guinea. Bathymetry mapping of this extensive reef and shoal system is vital for the protection of the Torres Strait allowing for the safe navigation of shipping and improved environmental management. Over past ten years, deep-water multibeam surveys have revealed the highly complex continental slope canyons in deeper Coral Sea waters. Shallow-water multibeam surveys conducted by the US-funded Source-to-Sink program revealed the extensive Fly River delta deposits. Airborne LiDAR bathymetry acquired by the Australian Hydrographic Office cover most of the Torres Strait and GBR reefs, with coverage gaps supplemented by satellite derived bathymetry. The Geoscience Australia-developed National Intertidal DIgital Elevation Model (NIDEM) improves the source data gap along Australia’s vast intertidal zone. We acknowledge the use of the CSIRO Marine National Facility (https://ror.org/01mae9353 ) in undertaking this research.” The datasets used were collected by the Marine National Facility on 13 voyages (see Lineage for identification). All source bathymetry data were extensively edited as point clouds to remove noise, given a consistent WGS84 horizontal datum, and where possible, an approximate MSL vertical datum. The 30 m-resolution grid is a fundamental dataset to underpin marine habitat mapping, and can be used to accurately simulate water mixing within a whole-of-GBR scale hydrodynamic model. This dataset is not to be used for navigational purposes.

This dataset contains bathymetry (depth) products from the compilation of all available source bathymetry data within Northern Australia into a 30 m-resolution Digital Elevation Model (DEM). The Northern Australia region includes a broad continental shelf over 400 km wide extending out from Western Australia and the Northern Territory, and stretching over a distance of ~1500 km. This region encompasses numerous shallow coral reefs including the offshore Sahul Banks, sand cays, drowned ancient river valleys, broad inner-shelf banks and a rugged coastline. Bathymetry mapping of the seafloor is vital for the protection of Northern Australia, allowing for the safe navigation of shipping and improved environmental management. Shallow- and deep-water multibeam surveys have revealed the highly complex seafloor of the continental shelf and adjacent slope canyons draining into the Indian Ocean and Timor Sea. Airborne LiDAR bathymetry acquired by the Australian Hydrographic Office cover most of the Sahul Banks reefs, with some coverage gaps supplemented by satellite derived bathymetry. The Geoscience Australia-developed Intertidal Elevation Model DEM improves the source data gap along Northern Australia’s vast intertidal zone.

The Torres Strait Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) on 12 Dec 2021. This surface was created from a contracted national reference survey between Goods Island and Goods Island cardinal mark, and Tuesday Island and the Herald Patches QLD, collected for the purpose of calibrating multibeam echosounders. It was conducted for the Australian Hydrographic Office as part of the Hydroscheme Industry Partnership Program, acquired using Kongsberg EM2040D, and processed using QPS Qimera. Seperate grids in 0.5m resolution are provided for the two surveyed sites within this survey area in MSL, LAT and Ellipsoid vertical datum. The dataset was then exported as a 0.5m resolution, 32 bit floating point GeoTIFF grid of the survey area. This dataset is not to be used for navigational purposes.
