SI 1005 Torres Strait Under Keel Clearance Bathymetry Survey (2021-2022)

December 2021 to January 2022 bathymetry survey acquired for the Australian Hydrographic Office by EGS Survey Pty. Ltd. Data was collected onboard the MV Sea Ranger and SMB White Shark in the Torres Strait, Queensland, using Kongsberg EM2040D and EM 2040C multibeam echosounders. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seafloor topography for maritime safety based on high-resolution bathymetry data.
• Analyzing underwater terrain features based on the 30-meter resolution grid.
• Supporting hydrographic charting and nautical publications based on survey data from the Australian Hydrographic Office.

Strengths

• Survey conducted over a defined period from 1 Dec 2021 to 24 Jan 2022.
• Data processed into a 30-meter resolution, 32-bit floating point GeoTIFF grid.
• Acquired using specific Kongsberg EM2040D and EM 2040C multibeam echosounders.

Limitations

• Dataset explicitly states it is not to be used for navigational purposes.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
