Great North East Channel Bathymetry Survey, Torres Strait 2022

Geoscience Australia Data provides a bathymetry grid from a survey conducted for the Australian Hydrographic Office between 26 Jan 2022 and 13 Apr 2022. The data was acquired using Kongsberg EM2040C and EM2040P multibeam echosounders and processed into a 30-meter resolution GeoTIFF grid. This dataset covers an area in the Torres Strait, Queensland, and is not for navigational use.

Use Cases

• Modeling seabed morphology based on high-resolution bathymetric data.
• Analyzing underwater terrain features in the Torres Strait region.
• Supporting marine habitat mapping and environmental studies using depth information.
• Providing a base layer for oceanographic and hydrodynamic modeling.

Strengths

• Data was acquired using high-precision Kongsberg EM2040C and EM2040P multibeam echosounders.
• The final product is a 30-meter resolution, 32-bit floating point GeoTIFF grid.
• Survey was conducted under the Hydroscheme Industry Partnership Program for the Australian Hydrographic Office.

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.
