South-west Corner and Perth Canyon Marine Park Bathymetry Survey, 2022

Five GeoTIFF files, including one at 64m and four at 128m resolution, represent bathymetric data from the South-west Corner and Perth Canyon Marine Parks. The Minderoo-UWA Deep-Sea Research Centre acquired the data aboard the MV Pangaea Ocean Explorer from March 24 to April 5, 2022, using a Kongsberg EM304 multibeam sonar. Dr. Todd Bond led the survey, and Dr. Yakup Niyazi processed the data, which was published with permission from Geoscience Australia.

Use Cases

• Modeling seafloor terrain and slope based on the 64m and 128m resolution bathymetric grids.
• Analyzing submarine canyon morphology in the Perth Canyon based on the processed multibeam sonar data.
• Creating base maps for marine habitat studies within the South-west Corner and Perth Canyon Marine Parks.
• Conducting geological studies of the continental shelf and slope using the high-resolution depth data.

Strengths

• Data was collected during a dedicated 13-day research voyage in March-April 2022.
• Processed using QPS Qimera v.2.5 software, suggesting a standardized workflow.
• Includes both 64-meter and 128-meter resolution products, offering flexibility for analysis at different scales.

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.
• The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
