25 files of processed multibeam data, side-scan mosaics from 15 boxes, and processed seismic data were collected during the 2001 SEA2 survey. The survey was carried out by the UK Department of Trade and Industry (now DECC) to identify potential offshore Special Areas of Conservation. Data covers three areas of the North Sea: Norfolk Coast, Dogger Bank, and Fladen Ground.
Use Cases
- Map seabed morphology and features like sandbanks based on multibeam and sidescan sonar data.
- Identify potential Special Areas of Conservation (SACs) based on features listed in the EU Habitats Directive.
- Guide sampling and photographic work for subsequent biological surveys using the acquired geophysical charts.
- Analyze sub-surface geological structures using the collected chirp seismic data.
Strengths
- Includes 25 files of processed multibeam data and side-scan mosaics from 15 boxes.
- Covers three distinct geographic areas of the North Sea for comparative analysis.
- Data collection was purpose-driven for a specific environmental assessment (SEA2).
Limitations
- Row count and column-level documentation are absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
- Data may reflect geographic and temporal bias inherent to the single 2001 survey campaign.
