Van Diemen Gulf Bathymetry Survey, 30m Resolution (2021)

Van Diemen Gulf (North-West Inshore Route), Northern Territory, Australia, is covered by this bathymetric survey. The data was acquired for the Australian Hydrographic Office by Guardian Geomatics between 26 June 2021 and 5 October 2021. It was processed using CARIS HIPS and SIPS software and exported as a 30-meter resolution GeoTIFF grid.

Use Cases

• Modeling seabed topography based on the 30-meter resolution bathymetric grid.
• Analyzing coastal and marine geomorphology in the Van Diemen Gulf region.
• Supporting marine spatial planning and environmental studies based on the survey area.
• Calibrating or validating other hydrographic or oceanographic models with the acquired data.

Strengths

• Survey conducted over a defined period from 26 Jun 2021 to 5 Oct 2021.
• Data processed to a specific 30-meter resolution using CARIS HIPS and SIPS software.
• Acquired using a Kongsberg EM2040-07 MKII multibeam echosounder.

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.
• Row count is unknown, which may limit suitability assessment.
