【 摘 要 】

Heights on land as well as depths in the sea are measured with reference to the surface of the sea or sea level. But the level of the sea is constantly changing under the influence of the rise and fall of the tide and of varying meteorological conditions. For that reason use is made of an average level called mean sea level, this datum being derived from tide observations.
