A High-resolution depth model for the North West Shelf and Outer Browse Basin (20210025C)

This resource contains a bathymetry compilation prepared by the University of Western Australia for the North West Shelf of Australia, between the Cape Range and the Dampier Peninsula.


The compilation includes, by decreasing resolution:

- Publicly available MBES datasets, made available by Geoscience Australia by December 2019.

- Satellite derived bathymetry produced using 1000+ images acquired between January 2017 and December 2019.

- Seismic derived bathymetry extracted from 100+ surveys acquired between 1981 and 2015.

- SRTM topography, reprocessed by Galant et al, 2011: https://pid.geoscience.gov.au/dataset/ga/72759

- 2009 Australian Bathymetry and Topography grid: https://pid.geoscience.gov.au/dataset/ga/67703


The Seismic and Satellite derived bathymetry grids are also available as individual layers.


The vertical and spatial accuracy of the datasets have been thoroughly assessed using high-resolution datasets including publicly available MBES and LADS surveys. The assessment indicates that the seismic derived bathymetry has a depth accuracy better than 1 m + 2% of the absolute water depths while the satellites derived bathymetry has a depth accuracy better than 1 m + 5% of the absolute water depths.


A detailed methodology is provided in: Lebrec et al, 2021. Towards a regional high-resolution bathymetry of the North West Shelf of Australia based on Sentinel-2 satellite images, 3D seismic surveys and historical datasets. (in prep.)
