The Permanent Service for Mean Sea Level (PSMSL) is the global data bank for long-term sea-level change information from tide gauges and bottom pressure recorders. It is responsible for the collection, publication, analysis, and interpretation of sea-level data from the global network of tide gauges. PSMSL provides services and advice to the international sea level community, including a range of derived-products. The main activities include: • Providing users with the mean sea level and delayed-mode datasets via the web, together with ancillary information and derived products, for example trends and anomalies (see: for further information). • Developing training information, and organising training courses, for operators of tide gauges and users of their datasets. • Responding to requests for information from national tide gauge agencies, decision makers (local councils, Parliamentary enquiries), the media and general public.
