HI1450 survey covers a 1239 square kilometer area in the Approaches to Cardigan Bay. The data was collected for the Maritime and Coastguard Agency's Civil Hydrography Programme from July to November 2014, adhering to IHO S44ed5 Order 1a standard. The British Geological Survey holds the samples and associated geological data.
Use Cases
- Analyze seafloor topography and depth variations across the 1239 sq km survey area for nautical charting.
- Validate bathymetric models against the IHO S44ed5 Order 1a standard for hydrographic quality control.
- Study geological sample data from the British Geological Survey to correlate with bathymetric features.
