Adolphus Channel to Great North East Channel Bathymetry Survey, 2023-2024

Australian waters in the Adolphus Channel to Great North East Channel region were surveyed for bathymetry between 16 November 2023 and 8 February 2024. The survey was conducted for the Australian Hydrographic Office by PHS under the Hydroscheme Industry Partnership Program. Data was acquired using Kongsberg multibeam sonar and processed into a 30-meter resolution GeoTIFF grid.

Use Cases

• Modeling seabed topography based on the 30-meter resolution bathymetric grid.
• Analyzing underwater terrain features for marine research based on the sonar-acquired data.
• Supporting coastal and marine spatial planning based on the high-resolution survey data.

Strengths

• Survey conducted over a defined period from 16 Nov 2023 to 8 Feb 2024.
• Data processed to a specific 30-meter resolution grid.
• Acquired using named Kongsberg EM2040-07/Kongsberg 2040P MKII sonar systems.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes.
