PSMSL
The permanent service for mean sea level : PSMSL
The PSMSL (Permanent Service for Mean Sea Level) is an international service which, since 1933, has been providing monthly and annual data on mean sea level from tide gauges from all over the world, past or present. For more details see the PSMSL pages.
Note: For tide gauges situated outside of France and co-located with GPS stations, SONEL provides a link with the PSMSL data in the station files in order to gather all of the relevant data concerning a given station in a single portal (tide gauge, GPS, levelling, benchmarks), and thus facilitate their analysis and interpretation.
