abstract:The Global Sea Level Observing System (GLOSS) is an Intergovernmental Oceanographic Commission program whose purpose is to measure sea level globally for long-term climate change studies. The program's purpose has changed since the 2004 Indian Ocean earthquake and the program now collects realtime measurements of sea level.
These include the international seismic monitoring network, the international array of sealevel measuring stations (the GlobalSeaLevelObservingSystem, the Global Telecommunication System of the World Meteorological Organization and associated public geostationary satellites) and the internet.
