A 78-square-kilometer reconnaissance bathymetric survey conducted for the UK Maritime and Coastguard Agency. The dataset includes focused surveys of Middle and South Cross Sand, covering 4 and 3 square kilometers respectively, performed to IHO S44ed4 Order 1 standard from May 23 to June 3, 2008. Data samples and associated geological information are curated by the British Geological Survey.
Use Cases
- Analyze bathymetric data from the 78-square-kilometer reconnaissance area for seabed mapping applications.
- Process focused survey data from the 4-square-kilometer Middle Cross Sand region for high-resolution depth modeling.
- Integrate geological data associated with the 3-square-kilometer South Cross Sand focus area for sediment studies.
- Validate survey standards by comparing collected data against the specified IHO S44ed4 Order 1 requirements.
Strengths
- Survey conducted to a defined international hydrographic standard (IHO S44ed4 Order 1).
- Covers a substantial 78-square-kilometer reconnaissance area with two focused sub-areas of 4 and 3 square kilometers.
- Provides a specific temporal snapshot from May 23 to June 3, 2008.
Limitations
- Specific data structure (rows, columns, file formats) and sample size are unknown.
- Data is over 15 years old and may not reflect current seabed conditions.
- Lacks details on data density, resolution, or measurement accuracy within the surveyed areas.
