Kangaroo Island (South-East) Bathymetry Survey, 30m Resolution (2022-2023)

Kangaroo Island (South-East) bathymetry data was acquired for the Australian Hydrographic Office between 1 Dec 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 a 30-meter resolution, 32-bit floating point GeoTIFF grid of the survey area.

Use Cases

• Modeling seafloor topography and habitat based on high-resolution bathymetry data.
• Analyzing coastal geomorphology and sediment transport patterns based on the 30m resolution grid.
• Supporting marine spatial planning and environmental impact assessments based on the defined survey area.
• Calibrating and validating oceanographic models using the sonar-derived depth measurements.

Strengths

• Data was acquired using specific, high-precision sonar systems (Kongsberg EM2040-07, EM2040-P, and EM2040-P SV MKII).
• Processed to a defined 30-meter resolution, 32-bit floating point GeoTIFF format.
• Survey has a specific temporal coverage from 1 December 2022 to 31 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.
