Van Diemen Gulf Bathymetry Survey at 30m Resolution, 2021

A 30-meter resolution bathymetric grid of Van Diemen Gulf, Northern Territory, was acquired for the Australian Hydrographic Office between 26 June and 5 October 2021. Data was collected using a Kongsberg EM2040-07 MKII multibeam echosounder from the vessels MV Offshore Guardian and MV Special Order. The processed dataset is provided as a 32-bit floating point GeoTIFF.

Use Cases

• Modeling seafloor topography and slope based on the 30-meter resolution bathymetric grid.
• Analyzing coastal erosion or sediment transport patterns in the Van Diemen Gulf region.
• Supporting marine habitat mapping and environmental studies using detailed depth data.
• Creating base maps for maritime research and planning, excluding navigational use as specified.

Strengths

• Data was acquired using a specific, high-resolution Kongsberg EM2040-07 MKII multibeam system.
• The final product is a 30-meter resolution grid, providing a consistent level of detail across the survey area.
• Survey has a defined temporal scope from 26 June 2021 to 5 October 2021.

Limitations

• The dataset explicitly states it is not to be used for navigational purposes, limiting its primary application.
• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• The total spatial extent (area in square kilometers) and data volume are not specified.
