Systematic surveying of the UK’s coastal waters is administered by the Maritime and Coastguard Agency (MCA) under a Civil Hydrography Programme. Under the programme, the MCA has issued a number of long-term commercial contracts to ensure accurate hydrographic information is gathered for updating the nation’s nautical charts and publications.
Routine re-surveys are undertaken in selected areas where the seabed is highly mobile. We analyse these surveys to identify changes that have occurred and assess whether the limits and survey frequency should be revised.
Pre 2012 analysis reports can be viewed via the UKHO archive website.
