The systematic survey of the UK’s coastal waters is administered by the Maritime and Coastguard Agency (MCA). 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 areas where the seabed itself is highly mobile. We analyse these surveys to identify changes that have occurred and apply updates to charts if necessary. We also assess whether the limits and survey frequency should be revised.
The UKHO has a moratorium of understanding to publish all re-surveys. Pre 2012 analysis reports can be viewed via the UKHO archive website
