About the National Tidal and Sea Level Facility

The National Tidal and Sea Level Facility (NTSLF) was established in 2002 to reflect the importance of national sea level monitoring to the public and government, as well as to the academic community.

The NTSLF comprises the UK National Tide Gauge Network, geodetic networks for monitoring vertical land movements, and gauges in the British Dependent Territories of the South Atlantic and Gibraltar.

NTSLF provides technical expertise to a wide community and supplies quality-controlled data with a range of practical and scientific applications including:

  • Tidal prediction
  • Flood warning
  • Navigation
  • Determination of extreme sea levels for coastal engineering design
  • Studies into climate change

The UK sea level science community is a major contributor to the work of the Intergovernmental Panel on Climate Change.

UK National Tide Gauge Network
Sea-levels are monitored by the UK National Tide Gauge Network which has sites all around the UK coastline.

Global sea-level monitoring
Tide gauge sites all around the World provide data and information about global sea-level changes. The Permanent Service for Mean Sea Level, based at the National Oceanography Centre Liverpool collects and analysis sea-level change on a global scale.


NTSLF partners

The UK National Tidal Gauge Network is owned and funded by the Environment Agency. Associated scientific research is funded by the National Environment Research Council (NERC) and the Department for Environment, Food & Rural Affairs (Defra).

Additional partners include the National Oceanography Centre (NOC) in Liverpool, British Oceanographic Data Centre (BODC) and British Isles GPS archive Facility (BIGF)
