Hay Point to Hydrographers Passage Bathymetry Survey, 2022

A bathymetry survey of the seafloor from Hay Point to Hydrographers Passage in Queensland, Australia. The data was acquired for the Australian Hydrographic Office by EGS between 13 August and 09 November 2022, using Kongsberg EM2040D and EM 2040C systems. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seabed topography based on the 30-meter resolution bathymetric grid.
• Analyzing coastal and marine geomorphology based on the survey area from Hay Point to Hydrographers Passage.
• Supporting marine spatial planning and environmental studies based on high-resolution bathymetric data.
• Calibrating or validating other bathymetric or oceanographic models based on the 2022 survey data.

Strengths

• Data was acquired using specific, high-end equipment: Kongsberg EM2040D and EM 2040C systems.
• The final product is a processed 30-meter resolution, 32-bit floating point GeoTIFF grid.
• The survey has a defined temporal coverage from 13 August to 09 November 2022.
• The survey was conducted under a formal program: the Hydroscheme Industry Partnership Program (HIPP).

Limitations

• The dataset is explicitly not to be used for navigational purposes, limiting its application.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
