A 2017 deployment of an Edgetech 2000-DSS combined side scan sonar and sub-bottom profiler, likely collecting high-resolution acoustic data. The instrument operated at frequencies of 100/400 kHz or 300/600 kHz for side scan and 2–16 kHz for sub-bottom profiling, capable of imaging in water depths up to 2000 meters. The data was collected by the Oceans & Atmosphere GSM team for research informing measurement, monitoring, and verification of carbon capture and storage projects in coastal waters.
Use Cases
- Analyze sub-surface geological structures based on high-resolution sub-bottom profiler data
- Map seabed features and morphology based on dual-frequency side scan sonar data
- Assess potential sites for carbon storage based on acoustic imaging of sediment layers
- Validate sonar instrument performance and settings for deep-water surveys
Strengths
- Instrument specifications are detailed, including dual-frequency configurations (100/400 kHz and 300/600 kHz) and a 2–16 kHz sub-bottom sonar
- System is capable of operating in water depths up to 2000 meters
- Data is associated with a specific research project focused on carbon capture and storage
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness should be verified; the last metadata update was 2026-05-05
