Lord Mayor Shoal to Pitt Shoals Bathymetry Survey, 30m Resolution (2023)

A 30-meter resolution bathymetric grid of the Lord Mayor Shoal to Pitt Shoals area in Australia, acquired between 1 October and 30 November 2023. The survey was conducted for the Australian Hydrographic Office using a Kongsberg EM2040 MKII multibeam echosounder and processed with CARIS HIPS and SIPS software. Data is provided as a 32-bit floating point GeoTIFF and is explicitly not for navigational purposes.

Use Cases

• Modeling seabed morphology and slope based on the high-resolution bathymetric grid.
• Analyzing underwater terrain features for marine habitat mapping based on the described survey area.
• Integrating bathymetric data with other oceanographic datasets for coastal zone management, leveraging the geospatial format.

Strengths

• Data acquisition used a specific, modern multibeam echosounder (Kongsberg EM2040 MKII).
• The dataset provides a defined 30-meter spatial resolution.
• The survey has a precise temporal coverage from 1 Oct 2023 to 30 Nov 2023.

Limitations

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