Hay Point to Hydrographers Passage Bathymetry Survey, 2022

A 30-meter resolution bathymetric grid covers the seafloor from Hay Point to Hydrographers Passage in Queensland. The survey was acquired for the Australian Hydrographic Office onboard the MV Sea Ranger and MV Brynda between August and November 2022. Data was processed from Kongsberg EM2040D and EM2040C systems and exported as a 32-bit floating point GeoTIFF.

Use Cases

• Modeling seabed morphology based on high-resolution bathymetry data
• Analyzing underwater terrain for marine habitat studies based on depth data
• Supporting coastal infrastructure planning based on detailed seafloor mapping
• Creating nautical charts for scientific reference based on processed survey data

Strengths

• Survey conducted with Kongsberg EM2040D and EM2040C multibeam echosounder systems
• Data processed and exported as a 30-meter resolution, 32-bit floating point GeoTIFF

Limitations

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