Van Diemen Gulf Bathymetry Survey at 30m Resolution, 2021

Bathymetry data for the Van Diemen Gulf (North-West Inshore Route) in the Northern Territory was acquired by Guardian Geomatics for the Australian Hydrographic Office. The survey was conducted from 26 June to 5 October 2021 using a Kongsberg EM2040-07 MKII multibeam sonar system. The processed data is provided as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seafloor topography based on high-resolution bathymetry data.
• Analyzing coastal and inshore underwater features for environmental studies.
• Supporting marine spatial planning based on detailed depth information.
• Calibrating or validating regional oceanographic models with precise depth data.

Strengths

• Data was acquired using a specific, modern multibeam sonar system (Kongsberg EM2040-07 MKII).
• The final product is a processed, georeferenced grid at a defined 30-meter resolution.
• Survey has a precise temporal coverage from 26 June to 5 October 2021.

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.
