Description
The North Wollongong (Bellambi Point to Stanwell Park), NSW Bathymetry Acquisition (20170028S) dataset contains 5m resolution bathymetry and backscatter data for the seabed. The NSW Department of Planning and Environment acquired the data using a multibeam sonar onboard the RV Bombora between August 13, 2017, and March 4, 2022. This baseline dataset was created to map the spatial distribution of seabed types as part of the SeabedNSW program.
Use Cases
Modeling seabed morphology and slope based on high-resolution bathymetry data.
Classifying seabed types and habitats based on backscatter intensity data.
Establishing a baseline for coastal erosion or sediment transport studies based on the survey's temporal coverage.
Integrating with other marine datasets for spatial planning based on the geospatial format.
Strengths
Data was collected over a nearly five-year period from August 2017 to March 2022, providing temporal depth.
High 5-meter spatial resolution for both bathymetry and backscatter layers.
Processing methodology and standard operating procedures are documented via a provided link.
Data is derived from a specific multibeam sonar system (R2Sonic 2022) and processed with industry-standard software.
Limitations
Description metadata is limited; actual data quality requires manual inspection after download.
Column-level documentation is absent; field semantics must be inferred after download.
The dataset is explicitly not to be used for navigational purposes, limiting its application scope.
