Apollo Marine Park Seabed Mapping with Multibeam Sonar, 2020

Seabed mapping data for Apollo Marine Park collected in 2020 using a Kongsberg 2040C multibeam sonar system aboard the MV Yolla. The survey covers 114 square kilometres and includes bathymetry at 2-metre resolution, backscatter at 1-metre resolution, water column data, and preliminary hard bottom classification. The data was collected by Deakin University in partnership with iXblue for Parks Australia and is aggregated by the Australian Ocean Data Network.

Use Cases

• Modeling seabed topography and habitat based on high-resolution bathymetry data.
• Analyzing seabed composition and texture based on backscatter intensity data.
• Identifying potential hard bottom features for ecological assessment based on the preliminary classification layer.
• Integrating water column data for studies on pelagic interactions with the seabed.

Strengths

• Provides continuous seabed mapping coverage over 114 square kilometres.
• Includes high-resolution data layers: 2-metre bathymetry and 1-metre backscatter.
• Data was collected using a specific, named instrument (Kongsberg 2040C) and vessel (MV Yolla).

Limitations

• This record was superseded on 11/11/2022; users should verify they have the latest version (eCat 147191).
• Column-level documentation is absent; field semantics must be inferred after download.
• The preliminary nature of the hard bottom classification suggests it may require validation.
