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).
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.
Data Policy
The data and products available through this web-site are made available in accordance with the
IOC Oceanographic Data Exchange Policy as adopted by the 22nd session of IOC Assembly in Resolution 6.
Data and products available on this web-site may not be used for any commercial purposes. Commercial users should contact the relevant data originators.
Disclaimer
The data presented under this service has not undergone any quality control and data is provided as received.
The main objective is to provide a fast status assessment of station availability and performance.
IOC, VLIZ and data suppliers accept no liability for any errors and/or delays in data or for interpretations, transactions, or any other use carried out on the basis thereof.
IOC and VLIZ do not guarantee that this web-site is available 24 hours/7 days a week.
Please note that the sampling frequency and data transmission frequency varies for the stations.
