Adolphus Channel Bathymetry Survey at 30m Resolution, 2023-2024

A bathymetry survey grid covering the Adolphus Channel to Great North East Channel area in Australia. The data was acquired for the Australian Hydrographic Office between 16 November 2023 and 8 February 2024 using Kongsberg multibeam sonar systems. The processed dataset is provided as a 30-meter resolution, 32-bit floating point GeoTIFF.

Use Cases

• Modeling seabed morphology and underwater terrain based on the bathymetric grid.
• Analyzing depth gradients and slope stability in the channel area.
• Supporting marine habitat mapping and environmental studies using the high-resolution depth data.
• Integrating with other marine datasets for coastal zone management planning.

Strengths

• Data was acquired using specific, professional-grade Kongsberg EM2040-07 and Kongsberg 2040P MKII sonar systems.
• The survey has a defined temporal coverage from 16 Nov 2023 to 8 Feb 2024.
• Processed output is a standardized 30-meter resolution, 32-bit floating point GeoTIFF grid.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
