Global Sea Level Observing System
Encyclopedia
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. The project is currently upgrading the over 290 stations it currently runs, so that they can send realtime data via satellite to newly set up national tsunami
centres. They are also fitting the stations with solar panel
s so they can continue to operate even if the mains power supply is interrupted by severe weather. The Global Sea Level Observing System does not compete with Deep-ocean Assessment and Reporting of Tsunamis

Intergovernmental Oceanographic Commission
The Intergovernmental Oceanographic Commission was established by resolution 2.31 adopted by the General Conference of UNESCO. It first met in Paris at Unesco Headquarters from 19 to 27 October 1961. Initially, 40 States became members of the Commission.The IOC is composed of its Member States ,...

2004 Indian Ocean earthquake
The 2004 Indian Ocean earthquake was an undersea megathrust earthquake that occurred at 00:58:53 UTC on Sunday, December 26, 2004, with an epicentre off the west coast of Sumatra, Indonesia. The quake itself is known by the scientific community as the Sumatra-Andaman earthquake...

Transducer
A transducer is a device that converts one type of energy to another. Energy types include electrical, mechanical, electromagnetic , chemical, acoustic or thermal energy. While the term transducer commonly implies the use of a sensor/detector, any device which converts energy can be considered a...
