19 square kilometers of seabed in Holm Channel were surveyed from May 12 to 24, 2004 under the Civil Hydrography Programme. The bathymetric data was collected by the Maritime and Coastguard Agency to IHO S44ed4 Order 1 standards and is curated by the British Geological Survey.
Use Cases
- Analyze bathymetric depth and seabed composition data from the 19 sq km survey area for nautical chart updates.
- Model seafloor topography using survey data collected to IHO S44ed4 Order 1 hydrographic standards.
- Assess geological sample data associated with the survey for coastal or marine research.
Strengths
- Data collection adheres to the defined IHO S44ed4 Order 1 hydrographic standard.
- Survey covers a specific 19 square kilometer area with a precise two-week collection period in May 2004.
- Dataset is managed and held by the authoritative British Geological Survey.
Limitations
- The dataset's specific structure, column definitions, and sample data are unavailable for review.
- Data is from a single, short survey in 2004 and may not reflect current seabed conditions.
- The total volume of data points (rows) and available file formats are unknown.
