Background

The objective of this service is
  • to provide information about the operational status of global and regional networks of real time sea level stations
  • to provide a display service for quick inspection of the raw data stream from individual stations.

This web-site initially focused on operational monitoring of sea level measuring stations in Africa and was developed from collaboration between Flanders Marine Institute (VLIZ) and the ODINAFRICA project of IODE. The site has since been expanded to a global station monitoring service for real time sea level measuring stations that are part of IOC programmes i.e. (i) the Global Sea Level Observing System Core Network; and (ii) the networks under the regional tsunami warning systems in the Indian Ocean (IOTWS), North East Atlantic & Mediterranean (NEAMTWS), Pacific (PTWS) and the Caribbean (CARIBE-EWS).

Long-term mean sea level (MSL) data

This GLOSS data center focusses on collecting and redistributing high frequency, relative sea level data in real-time.
Most stations provide values every minute and are updated each 5 minutes.
The GLOSS data centers at the Permanent Service for Mean Sea Level (PSMSL), the British Oceanographic Data Center (BODC) and the University of Hawaii Sea Level Center (UHSLC) perform the additional processing steps needed to calculate long-term mean sea level (MSL) data at hourly, daily, monthly and yearly averages.
Where available, the station detail page links to these mean sea level data series
