Sydney Harbour Bathymetry: High-Resolution Seabed Surface from 2004 Survey

A high-resolution 32-bit floating point GeoTIFF bathymetry surface was derived from multibeam echosounder data collected in Sydney Harbour from October 5–8, 2004. Geoscience Australia and the Coastal Cooperative Research Centre conducted the survey onboard the DSTO Workboat 440 using a Reson SeaBat 8125 (455 kHz) system. The data was collected under the Coastal Water Habitat Mapping Project to support assessments of seabed habitat, sediment characteristics, and coastal geomorphology.

Use Cases

• Modeling coastal geomorphology based on high-resolution bathymetry data.
• Assessing seabed habitat suitability based on derived bathymetric surface.
• Analyzing sediment transport patterns based on seafloor topography.

Strengths

• High-resolution 32-bit floating point GeoTIFF surface derived from processed multibeam data.
• Data collected using a Reson SeaBat 8125 (455 kHz) multibeam echosounder, a standard hydrographic instrument.
• Survey conducted by authoritative organizations Geoscience Australia and the Coastal Cooperative Research Centre.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the single 2004 survey.
