Cape Range and Cloates Canyons Bathymetry Survey, March-April 2020

A bathymetry survey from March 8 to April 8, 2020, led by Dr. Rachel Przeslawski of Geoscience Australia aboard the RV Falkor. The dataset contains 64m and 16m resolution geotiffs of submarine canyons in the Gascoyne Marine Park, produced from processed EM302 and EM710 multibeam sonar data. This high-resolution seafloor mapping data is intended to support scientific research and marine park management.

Use Cases

• Map seafloor geometry and depth for habitat modeling based on high-resolution bathymetry.
• Analyze submarine canyon morphology for geological research based on the described survey objectives.
• Support marine park zoning and management decisions based on detailed seafloor data.
• Study species diversity and distribution in relation to canyon features based on the described link between bathymetry and biota.

Strengths

• High-resolution data with 64m and 16m resolution geotiffs for depths shallower than 2560m.
• Data collected during a dedicated scientific survey from March 8 to April 8, 2020, using Kongsberg EM302 and EM710 multibeam sonar systems.
• Produced by a collaborative team from Geoscience Australia, Curtin University, Western Australian Museum, and Scripps Institution of Oceanography.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
