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).

Research quality data

Provision of low frequency and high frequency research quality sea level data is not the aim of this service. Such data is available from the GLOSS designated data centers at the Permanent Service for Mean Sea Level (PSMSL), the British Oceanographic Data Center (BODC), the University of Hawaii Sea Level Center (UHSLC) or the data originators.
Additionally, you can click on the 'QC data' link on the station details page, to retrieve research quality data.
