Great North East Channel Bathymetry Survey, Torres Strait 2022

A 30-meter resolution bathymetry grid of the Great North East Channel (South-West) in Torres Strait, Queensland. The survey was acquired for the Australian Hydrographic Office by EGS Survey Pty. Ltd. onboard the MV Sea Ranger and SMB Independence between 26 January 2022 and 13 April 2022. Data was collected using Kongsberg EM2040C and EM2040P multibeam sonar systems and processed with QPS Qimera software.

Use Cases

• Model seabed topography for marine navigation planning based on bathymetry data.
• Analyze underwater terrain changes in a dynamic channel environment based on the survey area.
• Integrate sonar-derived depth data into coastal zone management maps based on the GeoTIFF grid.

Strengths

• Specific survey period from 26 Jan 2022 to 13 Apr 2022.
• High-resolution 30-meter grid derived from Kongsberg EM2040C and EM2040P sonar.
• Clear provenance from the Australian Hydrographic Office and EGS Survey Pty. Ltd.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The dataset is explicitly not for navigational purposes, restricting its primary application.
