HI1522 survey data covers 193 square kilometers across eight focused areas in the Thames Estuary, including Black Deep and Buxey Sand. The survey was conducted by contractor EGS for the Maritime and Coastguard Agency from July to October 2016, adhering to IHO S44ed5 Order 1a standards. Data and geological samples are archived at the British Geological Survey.
Use Cases
- Analyze bathymetric changes in the Thames Estuary by comparing survey data from the eight named focused areas (e.g., TE10 Buxey Sand, TE8 Rough Shoals).
- Assess seabed composition and geological features using the associated geological samples held by the British Geological Survey.
- Validate hydrographic chart accuracy for navigation safety using the IHO S44ed5 Order 1a standard survey data.
- Map the spatial distribution of surveyed areas using the provided Area in SqKm measurements for each focused zone.
Strengths
- Survey conducted to a defined international hydrographic standard (IHO S44ed5 Order 1a).
- Covers a total of 193 square kilometers across eight distinct geographic areas in the Thames Estuary.
- Specific temporal coverage from 06/07/2016 to 29/10/2016 for the resurvey activities.
- Data and physical samples are curated by the authoritative British Geological Survey.
Limitations
- No columnar data structure, row count, or sample data is provided, limiting immediate analytical use.
- The dataset description is highly technical and assumes user knowledge of hydrographic survey codes and area designations.
- Data is from a single 2016 survey period, limiting temporal trend analysis without prior or subsequent surveys.
