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.
