How do they measure tide height
WebJun 17, 2013 · A tide gauge is a piece of equipment used for measuring the changes in sea level with respect to a height reference surface. Although tide gauges have not been used as a primary source of sea-level data for several years, they play a key role in the instrumentation at modern-day tide gauge locations to verify water level. Sensors continuously record the height of the water level with respect to a height reference surface close to the geoid. Water enters the device by the bottom pipe (far end of the tube, see picture), and electronic sensors measure its height and send the data to a tiny computer. Historical data are available for about 1,450 stations worldwide, of which about 950 have provided updates to the global data center since January 2010. At some places records cover centuries, f…
