High-Resolution Bathymetric Maps of Cape Range and Cloates Canyons

March to April 2020 bathymetry data from the RV Falkor research vessel, mapping unexplored submarine canyons in the Gascoyne Marine Park. The dataset contains 64m and 16m resolution 32-bit GeoTIFFs of the Cape Range and Cloates Canyons area, produced from processed EM302 and EM710 multibeam sonar data. The survey was led by Dr. Rachel Przeslawski of Geoscience Australia with a team from Curtin University, Western Australian Museum, and Scripps Institution of Oceanography.

Use Cases

• Analyze seafloor geometry and depth from the 32-bit GeoTIFF raster to model submarine canyon habitat complexity.
• Use the 16m resolution bathymetry layer for detailed geomorphological feature extraction in water depths shallower than 2560m.
• Correlate high-resolution bathymetric features with biological survey data to understand species distribution in the canyons.
• Integrate the 64m resolution layer for regional-scale seabed terrain analysis and marine park zoning.

Strengths

• High-resolution 16m and 64m bathymetric grids derived from Kongsberg EM302 and EM710 multibeam systems.
• Data collected during a dedicated 32-day research cruise (8 March - 8 April 2020) targeting unexplored areas.
• Processed and published by Geoscience Australia, a national geoscience agency.

Limitations

• Spatial coverage is limited to the specific Cape Range and Cloates Canyons area within the Gascoyne Marine Park.
• Data is not intended for navigational purposes, indicating it may not meet real-time charting standards.
• The dataset's utility for time-series analysis is limited to a single survey period in 2020.
