| Abstract |
GLOSS is a project linking an international network of sea level measuring stations, co-ordinated by the IOC. Some 300 stations world-wide contibute to GLOSS. These provide standardized information on the level of seas locally, regionally and globally. Such information is important as sea level is considered a good indicator of ocean heat, which directly affects the global climate.
GLOSS operates a set of tide gauges as part of its monitoring activities. These will be connected as a network and to the global geodetic reference system, established by the International Earth Rotation Service (IERS). The development of new geodetic techniques, based on Very Long Baseline Interferometry (VLBI) , the Global Positioning System (GPS) and absolute gravity measurements have created the opportunity to link these tidal gauges to a highly accurate global reference system.
