North-East Beagle Gulf and Clarence Strait Bathymetry Survey, 2021

The North-East Beagle Gulf and Clarence Strait bathymetry survey was acquired for the Australian Hydrographic Office onboard the MV Offshore Guardian from 1 May 2021 to 13 July 2021. This dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid processed from data collected with a Kongsberg EM2040 07 MK II multibeam sonar. The survey was conducted by Guardian Geomatics as part of the Hydroscheme Industry Partnership Program.

Use Cases

• Modeling seafloor topography and slope based on the 30-meter resolution bathymetry grid.
• Analyzing underwater features in the North-East Beagle Gulf and Clarence Strait based on the high-resolution sonar data.
• Integrating bathymetric data with other marine datasets for coastal zone management based on the geospatial format.
• Conducting baseline studies for marine infrastructure planning based on the survey's geographic coverage.

Strengths

• Data was collected with a specific, high-resolution instrument (Kongsberg EM2040 07 MK II).
• The final product is a processed 30-meter resolution grid, providing a consistent spatial scale.
• Survey has a defined temporal coverage from 1 May 2021 to 13 July 2021.
• Dataset originates from a contracted survey for the authoritative Australian Hydrographic Office.

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.
• The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
