Cape Range and Cloates Canyons Bathymetry Survey Data

High-resolution bathymetry data from the Coral Sea was collected aboard RV Falkor from March to April 2020. Dr. Rachel Przeslawski led a team from Geoscience Australia and other institutions to map unexplored submarine canyons in the Gascoyne Marine Park. The dataset includes 64m and 16m resolution 32-bit geotiffs for water depths shallower than 2560m.

Use Cases

• Model submarine canyon geometry based on high-resolution bathymetry data
• Support marine park management decisions based on mapped canyon features
• Analyze species diversity correlations with canyon depth and shape
• Conduct scientific research on Australia's marine estate using sonar-derived maps

Strengths

• Data collected using Kongsberg EM302 and EM710 multibeam sonar systems
• Includes two resolution levels (64m and 16m) for depths shallower than 2560m
• Survey conducted by a multi-institutional team including Geoscience Australia and Scripps Institution of Oceanography

Limitations

• Dataset is not to be used for navigational purposes
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
