Van Diemen Gulf Bathymetry Survey: 30m Resolution Grid (2021)

Van Diemen Gulf, Northern Territory, Australia, was surveyed for bathymetry data between 26 June and 5 October 2021. The survey was conducted for the Australian Hydrographic Office by Guardian Geomatics under the Hydroscheme Industry Partnership Program. Data was acquired using a Kongsberg EM2040-07 MKII multibeam echosounder and processed into a 30-meter resolution GeoTIFF grid.

Use Cases

• Modeling seafloor topography based on high-resolution bathymetric data.
• Analyzing underwater terrain features for marine research based on the 30m resolution grid.
• Studying coastal and inshore marine geography in Northern Australia based on the defined survey area.

Strengths

• Data was acquired using a specific, high-grade instrument (Kongsberg EM2040-07 MKII).
• The final product is a 32-bit floating point GeoTIFF with a defined 30-meter resolution.
• The survey has a precise temporal coverage from 26 Jun 2021 to 5 Oct 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, limiting its application scope.
