Shellharbour Seabed Landforms Derived from Multibeam Echosounder Data 2022

Multibeam echosounder bathymetry data collected offshore of Shellharbour, NSW in 2017, covering depths from 10 to 64 meters. This dataset classifies seabed landforms into reefs, peaks, plains, scarps, depressions, and channels using a toolset developed by the NSW Coastal and Marine Unit. It provides baseline information for marine environment managers and users.

Use Cases

• Map the distribution of submerged reefs based on the classified landform features.
• Analyze seabed morphology for coastal engineering projects based on classified scarps and depressions.
• Model marine habitat suitability based on the delineated areas of reefs and plains.
• Support marine spatial planning and conservation efforts based on the classified seabed features.

Strengths

• Bathymetry data coverage extends from Port Kembla to Bass Point.
• Classification uses a publicly available toolset (Seabed Landforms Classification Toolset) with a cited 2023 publication.
• Data contributes toward understanding submerged reef distribution along the NSW coast.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
