The UK tide gauge and sea level catalogue holds metadata for tide gauges currently operating in the UK. Tide and sea level data described in this catalogue have been collected and quality controlled to different standards to suit the purposes of the specific collection programmes. The highest quality controlled data available, such as the network operated by the National Tide and Sea Level Facility (NTSLF), can be used to evaluate long term sea level changes, and can be used in combination with information from advanced geodetic techniques to study the contributions to those changes from vertical land movements and changes in ocean volume. Users should refer to the data providers for exact location and details. If you identify any errors or would like to add your own tide and sea level metadata please email webmaster@oceannet.org
