Adolphus Channel Bathymetry Survey: 30m Resolution Grid, 2023-2024

Australian waters from Adolphus Channel to Great North East Channel were surveyed for bathymetry between 16 November 2023 and 8 February 2024. The Australian Hydrographic Office contracted the survey via the Hydroscheme Industry Partnership Program, using Kongsberg multibeam sonar systems. Data was processed with CARIS software and exported as a 32-bit floating point GeoTIFF grid at 30-meter resolution.

Use Cases

• Modeling seabed terrain and slope based on the 30-meter resolution bathymetric grid.
• Analyzing underwater feature changes over time based on the 2023-2024 survey period.
• Integrating bathymetric data with other marine datasets for habitat mapping based on the geospatial format.
• Conducting coastal and marine spatial planning based on high-resolution depth data.

Strengths

• Data was acquired with specific, professional-grade equipment (Kongsberg EM2040-07/Kongsberg 2040P MKII).
• The final product has a defined, high-resolution grid specification (30-meter, 32-bit floating point GeoTIFF).
• Survey has a precise temporal coverage (16 Nov 2023 – 8 Feb 2024).

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.
