The site serves as a global station monitoring service for real time sea level measuring stations that are part of IOC programs such as the Global Sea Level Observing System Core Network, 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).
The objective of this service is to provide information about the operational status of global and regional networks of real time sea level stations and to provide a display service for quick inspection of the raw data stream from individual stations.
