Torres Strait Bathymetry Survey at 30m Resolution, 2021-2022

A bathymetry survey conducted from 1 December 2021 to 24 January 2022 for the Australian Hydrographic Office. The data was acquired by EGS Survey Pty. Ltd. using Kongsberg multibeam sonar systems and processed into a 30-meter resolution GeoTIFF grid covering an area in the Torres Strait, Queensland.

Use Cases

• Modeling seafloor terrain based on the 30-meter resolution bathymetry grid.
• Analyzing underwater features in the Torres Strait based on the high-resolution survey data.
• Supporting marine spatial planning based on the detailed depth information.
• Calibrating or validating other oceanographic models based on the sonar-acquired data.

Strengths

• Data was acquired using specific, high-grade equipment (Kongsberg EM2040D and EM 2040C multibeam sonar).
• Processed output is a 30-meter resolution grid, providing a defined level of detail.
• Survey has a precise temporal coverage from 1 Dec 2021 to 24 Jan 2022.

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.
