Content: The measurement of the mean sea level can give insight into the effects of climate change. The rise of the sea level has been an indication of the progress of global warming. The term “above sea level” is a common phrase used when measuring the altitude of an area. It refers to the above mean sea level. How Is Sea Level Measured? The determination of the mean sea level is a challenging task considering the several factors which affect sea level. The sea is always in constant movement, influenced by several factors including tides, temperatures, storm surges and wind. Before the invention of the satellite systems, mean sea levels were measured using the tide gauge device that measured the height of water about a fixed point on land. A change in the mean sea level can be influenced by real changes in the sea level or changes in the land on which the tide gauge is used. Tide gauge reflects a short-term influence of the factors affecting the sea level introducing a larger margin of error.
