The Global Sea Level Observing System (GLOSS) is an international sea level monitoring programme. Established in 1985 by the Intergovernmental Oceanographic Commission (IOC) of UNESCO, it currently has 90 member nations worldwide. It was created to produce high-quality in situ sea level observations and compile them into databases accessible to operational and research users. As this is a global undertaking it is necessary for this programme to be run by several agencies around the world to process all the data collected.
As part of a sea level monitoring station, tide gauges are equipped with sensors that continuously record the height of the water.
Tide gauge observations are used to collect data on:
- Sea level
GLOSS observations contribute to climate monitoring and operational services. Some examples of applications are:
- Monitoring sea level rise and decadal ocean variability
- Surface currents and upper ocean heat content
- Tidal processes
- Storm surges and tsunamis
