Abbot Point to Hydrographers Passage Bathymetry Survey, 2020-2021

Bathymetry data for a section of the Two-Way Route from Abbot Point through Hydrographers Passage, Queensland. The survey was acquired for the Australian Hydrographic Office by iXblue Pty Ltd onboard the RV Escape between 6 October 2020 and 16 March 2021. The processed dataset is a 30-meter resolution, 32-bit floating point GeoTIFF grid.

Use Cases

• Modeling seabed topography based on the 30-meter resolution bathymetry grid.
• Analyzing changes in coastal shipping channels based on the surveyed Two-Way Route section.
• Supporting marine habitat mapping based on the high-resolution depth data.
• Validating hydrodynamic models using the precise bathymetric measurements.

Strengths

• Data was acquired using a Kongsberg EM 2040 multibeam echosounder, a high-precision instrument.
• The dataset provides a specific 30-meter resolution grid for the defined survey area.
• The survey has a precise temporal coverage from 6 Oct 2020 to 16 Mar 2021.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The description explicitly states the dataset is not to be used for navigational purposes.
