Maritime and Coastguard Agency (MCA) bathymetric survey HI1459 covers multiple areas of the Thames Estuary, with surveyed areas ranging from 3 to 69 square kilometers. The data was collected by contractor EGS during a resurvey from June 16 to July 16, 2014, and is held by the British Geological Survey.
Use Cases
- Analyze seabed depth variations across surveyed areas like TE6 Black Deep and TE5a Long Sand for nautical chart updates.
- Model sediment distribution or geological features using the associated geological data from the Thames Estuary.
- Assess survey coverage and density by comparing the Area in SqKm metrics for different zones such as TE3a Sunk and TE3 South Ship Head.
Strengths
- Data collection followed the IHO S44ed5 Order 1a hydrographic survey standard.
- Survey covers seven distinct Thames Estuary areas with quantified sizes, including a 69 sq km zone.
Limitations
- Specific data structure (rows, columns, file formats) is unknown, complicating direct analytical use.
- Data is from a single month in 2014 and may not reflect current seabed conditions.
