Van Diemen Gulf Bathymetry Survey, Northern Territory, Australia

Australian Hydrographic Office contracted Guardian Geomatics to acquire bathymetry data for the Van Diemen Gulf (North-West Inshore Route) in the Northern Territory. The survey was conducted from the MV Offshore Guardian and MV Special Order between 26 June 2021 and 5 October 2021. Data was processed using CARIS HIPS and SIPS software and exported as a 30-meter resolution GeoTIFF grid.

Use Cases

• Model seabed topography for coastal engineering projects based on the 30-meter resolution bathymetry grid.
• Analyze underwater terrain features for marine habitat mapping based on the detailed survey data.
• Support maritime safety and planning studies based on the high-resolution hydrographic data.
• Integrate bathymetric data with other marine datasets for environmental research based on the geospatial format.

Strengths

• Data acquired using a Kongsberg EM2040-07 MKII multibeam echosounder, suggesting high-resolution seabed mapping.
• Survey conducted over a defined period from 26 Jun 2021 to 5 Oct 2021, providing temporal specificity.
• Processed and gridded data is available as a 30-meter resolution, 32-bit floating point GeoTIFF.

Limitations

• Dataset explicitly states it is 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.
