Kangaroo Island South-East Bathymetry Survey 2022-2023

Kangaroo Island (South-East) bathymetry data was acquired for the Australian Hydrographic Office between 1 December 2022 and 31 May 2023. The survey was conducted by Precision Hydrographic Services under the Hydroscheme Industry Partnership Program using Kongsberg EM2040 multibeam sonar systems. The processed dataset is provided as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seabed terrain based on high-resolution bathymetric data.
• Analyzing underwater features for marine habitat mapping based on the survey area.
• Supporting hydrographic chart updates based on the processed sonar data.

Strengths

• Data acquired using Kongsberg EM2040 series multibeam sonar systems.
• Processed and exported as a 30-meter resolution GeoTIFF grid.
• Survey conducted over a defined six-month period from December 2022 to May 2023.

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.
