Beagle Gulf Bathymetry Survey Data from 2021

A bathymetry survey was conducted in the North-East Beagle Gulf and Clarence Strait, Northern Territory, from 1 May 2021 to 13 Jul 2021. The data was acquired for the Australian Hydrographic Office using a Kongsberg EM2040 07 MK II multibeam sonar system onboard the MV Offshore Guardian. Processed data is available as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Model seabed topography based on high-resolution bathymetry data.
• Analyze underwater terrain for marine navigation planning.
• Integrate bathymetric data with other marine environmental datasets.
• Study sediment transport and deposition patterns in the Beagle Gulf.

Strengths

• Survey conducted over a defined period from 1 May 2021 to 13 Jul 2021.
• Data processed to a specific 30-meter resolution grid.
• Acquired using a named Kongsberg EM2040 07 MK II multibeam sonar system.

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.
