Edgetech 2000-DSS sonar data was collected in 2017 to support measurement, monitoring, and verification for carbon capture and storage projects in Australian coastal waters. The instrument combines side-scan sonar with a high-resolution sub-bottom profiler capable of imaging in water depths up to 2000 meters. This dataset is managed by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Characterizing sub-seafloor geology for potential CO2 storage site assessment based on sub-bottom profiler data.
- Analyzing seafloor morphology and features using combined side-scan sonar frequencies mentioned in the description.
- Developing baseline models for environmental monitoring and verification (MMV) of carbon storage projects in coastal waters.
- Calibrating sonar imaging techniques for high-resolution profiling in water depths up to 2000 meters.
Strengths
- Instrument specifications are detailed, including dual-frequency side-scan sonar (100/400 kHz and 300/600 kHz) and a 2–16 kHz sub-bottom profiler.
- Data is associated with a specific research vessel (MV Bluefin) and year (2017), providing clear context.
- The dataset is hosted by the authoritative Australian Ocean Data Network.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- The specific geographic coverage of the survey is not detailed in the provided metadata.
