Jervis Bay Benthic Habitat Mapping with Co-Located Physical and Biological Data

A series of short field surveys collected high-resolution multibeam acoustic data and underwater video footage of soft-sediment habitats in Jervis Bay, New South Wales. Geoscience Australia staff conducted this work as part of the CERF Marine Biodiversity Hub's Surrogates Program to research physical parameters as biodiversity surrogates. The outputs include mapped video characterisations, co-located sediment and infauna samples, and seabed current data from a trial acoustic doppler current profiler.

Use Cases

• Train models to predict benthic biodiversity patterns based on high-resolution multibeam acoustic data.
• Characterize soft-sediment habitat types (e.g., polychaete mounds, sand flats) using co-located sediment and biotic samples.
• Validate the use of physical variables as surrogates for biological patterns in shallow marine environments.
• Map seabed relief and bedform types from processed underwater video transects and associated GIS layers.

Strengths

• Includes high-resolution multibeam acoustic datasets for priority coastal areas.
• Provides co-located physical and biological data, including sediment samples for multiple analyses (geochemical, biogeochemical, sedimentological).
• Contains high-quality underwater video footage with real-time habitat characterisations processed into GIS map layers.

Limitations

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