South-west Corner and Perth Canyon Marine Park Bathymetry Survey

March 24 to April 5, 2022, the Minderoo-UWA Deep-Sea Research Centre collected bathymetric data in the South-west Corner and Perth Canyon Marine Parks using a Kongsberg EM304 multibeam sonar aboard the MV Pangaea Ocean Explorer. The processed data comprises 64m-resolution and 128m-resolution 32-bit floating point GeoTIFF files, created with QPS Qimera software. This dataset is published with permission from Geoscience Australia and is not intended for navigational use.

Use Cases

• Map underwater topography based on processed bathymetry data
• Analyze seabed features for marine park management based on high-resolution sonar surveys
• Model ocean floor terrain for geological studies based on the derived GeoTIFF files
• Integrate bathymetric layers into broader marine spatial planning based on the defined study area

Strengths

• Data was collected using a Kongsberg EM304 multibeam sonar, a specific high-precision instrument
• Includes a 64m-resolution and four 128m-resolution GeoTIFF files, providing multiple scales of analysis
• Processing was performed with QPS Qimera v.2.5 software, indicating a standardized workflow

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is explicitly not for navigational purposes, restricting its application scope
