Google Earth

The global network of tide gauges that contribute data to the PSMSL can be viewed using Google Earth. It is useful to see the spread of stations and compare the number of them in some areas relative to others. To view the network of stations you will have to follow these instructions - [More].

Permanent Service for Mean Sea Level

Welcome to the Permanent Service for Mean Sea Level (PSMSL), hosted here at the Proudman Oceanographic Laboratory (POL). The PSMSL was established in 1933, and is the global data bank for long term sea level change information from tide gauges. The PSMSL collect data from several hundred gauges situated all over the globe.

Survey of the Tide Gauge Infrastructure in Europe

PSMSL members recently completed a report on the tide gauge infrastructure in Europe that includes the technical requirements for detecting tsunamis. The report was written as part of the Tsunami Risk ANd Strategies For the European Region (TRANSFER) project.

Updated Sea Level Reconstruction

Church and White recently updated their sea level reconstruction, which is based on tide gauge and altimeter data. Their time series now includes data to 2007. In addition, Jevrejeva, Moore, Grinsted and Woodworth have also contributed their sea level reconstruction since 1700. Both records can be found in the Author archive.

PSMSL 75th Anniversary

PSMSL organised three events in celebration of its 75th Anniversary. The highlight of the year was 'Liverpool, Home of Sea Level Science: Sea Level Rise and Climate Change', a session at the September 2008 meeting of the British Association Festival of Science in Liverpool. A number of distinguished speakers from the UK and abroad presented an overview of the measurements and causes of sea level change, as well as the history of this research at Liverpool.

In addition, PSMSL gathered scientific experts to discuss ongoing research into sea level. It planned a special Interdivision Session at the 2008 Assembly of the European Geophysical Union (abstract and contributed presentations.) Furthermore, it sponsored the Geological Society's William Smith Meeting 2008. The meeting was titled "Observations and Causes of Sea-Level Changes on Millennial to Decadal Timescales" and occurred 1-2 September 2008.

PSMSL commentaries

We have started a page in which 'commentaries' of records in the data set can be posted for the interest of other users of the data set - more information.

PSMSL and Africa

There are major gaps in the global sea-level network in Africa, which need filling. PSMSL and the Inter-governmental Oceanographic Commission (IOC) have co-operated in installing or refurbishing a dozen tide gauges as part of the GLOSS, ODINAFRICA and Indian Ocean Tsunami Warning System programmes. These stations are based on radar and pressure gauge technology.

The Global Sea Level Observing System (GLOSS)

GLOSS aims at the establishment of high quality global and regional sea level networks for application to climate, oceanographic and coastal sea level research.
