About us

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 (IPCC).

UK Tide Gauge Network
Sea-levels are monitored by the UK 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 glodal sea-level changes. The Permanent Service for Mean Sea Level, based at POL collects and analysis sea-level change on a global scale.
