The Irish Sea between Ireland, the Isle of Man, and north Wales was surveyed as part of the UK's Strategic Environmental Assessment SEA6. The dataset includes processed multibeam and sidescan sonar files, raw seismic data, and cruise reports collected from the SV Meridian vessel.
Use Cases
- Map seabed topography and bathymetry based on the processed multibeam data.
- Analyze seabed texture and object identification based on the sidescan sonar mosaics.
- Investigate sub-surface sediment layers based on the chirp seismic data.
- Contextualize survey findings and methodology based on the available cruise reports.
Strengths
- Includes 11 processed gridded multibeam files and 11 sidescan mosaic files.
- Provides raw data for multibeam, sidescan sonar, and seismic sources, allowing for custom processing.
- Contains supporting documentation in the form of cruise reports.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
- Row count and dataset size are unknown, which may limit suitability assessment.
