Tide gauge networks and data

The NTSLF receives data from the UK National Tide Gauge Network, as well as from gauges in the South Atlantic, Antarctica, Gibraltar and British Overseas Territories.

The UK National Tide Gauge Network

The UK National Tide Gauge Network of sea level gauges was established after violent storms in the North Sea in 1953 resulted in serious flooding in the Thames Estuary. The network is run by the Tide Gauge Inspectorate, recording tidal elevations at 44 locations around the UK coast. – Read more →

Other networks

  • ACCLAIM
    The ACCLAIM (Antarctic Circumpolar Current Levels by Altimetry and Island Measurements) programme in the South Atlantic Ocean and Southern Ocean consists of measurements from coastal tide gauges and bottom pressure stations, together with an ongoing research programme in satellite altimetry – Read more →
  • Gibraltar sea level station
    Ocean currents flowing through the Strait of Gibraltar cause the level of the Mediterranean Sea to rise and fall, and ultimately affect the ecosystems of the region across a wide area; the Gibraltar station is part of the Global Sea Level Observing System – Read more →
  • Ocean Data and Information Network for Africa (ODINAFRICA)
    Our engineers participated in the ODINAFRICA project, funded by the IOC/UNESCO to set up an African tide gauge network – Read more →

Tide measurement devices

The Tide Gauge Inspectorate at the National Oceanography Centre Liverpool is responsible for modernising and maintaining the network to obtain high quality tidal information through telemetry. There are several types of tide gauge that have been developed over time with advancing technology. – Read more →

Tide gauge instrumentation (main NOC website)

Until the early 19th Century, sea-level measurements were made using tide poles or staffs. These still form part of modern-day tide gauge instrumentation, but have not been used as a primary source of sea-level information since the introduction of self-recording tide gauges. Tide gauge technology has advanced considerably over the last few decades. – Read more →
