SI 1046 Howard Channel Bathymetry Survey, 30m Resolution (2023)

A bathymetry survey of the Howard Channel in Australia, acquired between 9 August 2023 and 13 September 2023. The dataset was collected for the Australian Hydrographic Office by EGS Australia using a Kongsberg EM2040C multibeam echosounder. Processed data is provided as a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seabed topography and depth based on the 30m resolution bathymetric grid.
• Analyzing underwater channel morphology based on high-resolution survey data.
• Supporting marine spatial planning and environmental studies based on the defined survey area.
• Integrating bathymetric data with other marine datasets based on the geospatial format.

Strengths

• Survey conducted with a specific high-resolution instrument (Kongsberg EM2040C).
• Data processed using industry-standard software (CARIS HIPS and SIPS, QIMERA).
• Explicit temporal coverage from 9 Aug 2023 to 13 Sep 2023.
• Dataset provides a specific spatial data resolution (30 meters).

Limitations

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