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

Bathymetry data for an area off Kangaroo Island (South-East) 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 multibeam echosounders. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seafloor topography and slope based on the bathymetry grid.
• Analyzing underwater habitat suitability based on depth and terrain data.
• Supporting marine spatial planning and environmental impact assessments based on the high-resolution survey area.
• Calibrating or validating regional oceanographic models based on the detailed bathymetric measurements.

Strengths

• Data was acquired using Kongsberg EM2040 series multibeam echosounders, which are industry-standard instruments.
• The dataset provides a 30-meter resolution grid, offering a detailed view of the seafloor.
• The survey has a defined temporal coverage from 1 Dec 2022 to 31 May 2023.

Limitations

• The description explicitly states 'This dataset is not to be used for navigational purposes.', limiting its application.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
