Sea level is generally used to refer to mean sea level (MSL). This is the average level for the surface of one or more of Earth's oceans. MSL is a type of standardised geodetic reference point. It is used, for example, as a geodetic datum in cartography and marine navigation.
Mean sea level is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.
