Cape Range and Cloates Canyons Bathymetry Survey, 2020

High-resolution 64m and 16m bathymetry data from the Gascoyne Marine Park, collected aboard the RV Falkor from March to April 2020. The survey, led by Dr. Rachel Przeslawski of Geoscience Australia, mapped unexplored submarine canyons to support research on species diversity and marine park management. This dataset is a 32-bit geotiff produced from processed EM302 and EM710 multibeam sonar data.

Use Cases

• Modeling submarine canyon geometry and depth based on high-resolution bathymetry data
• Researching species diversity and habitat distribution in the Gascoyne Marine Park
• Supporting marine park management decisions with detailed seafloor maps
• Analyzing seabed features for geological and oceanographic studies

Strengths

• Data was collected using Kongsberg EM302 and EM710 multibeam sonar systems, suggesting high technical quality
• Survey was conducted by a team from Geoscience Australia, Curtin University, Western Australian Museum, and Scripps Institution of Oceanography
• Dataset provides two resolution levels (64m and 16m) for water depths shallower than 2560m

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
