Sea level - Wikipedia
WEBMean sea level (MSL, often shortened to 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.
Sea level - Simple English Wikipedia, the free encyclopedia
WEBSea 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 …
Past sea level - Wikipedia
WEBDuring the glacial-interglacial cycles over the past few million years, the mean sea level has varied by somewhat more than a hundred metres. This is primarily due to the growth and decay of ice sheets (mostly in the northern hemisphere) …
What Is The Mean Sea Level And What Is Its Significance?
WEBMay 3, 2018 · The mean sea level is a scientific term that is used to describe the average height of the oceans around the world. This average is determined by using the measurements of less active water, otherwise known as still or calm water, to avoid any possible increases due to waves or wind.
Height above mean sea level - Wikipedia
WEBHeight above mean sea level is a measure of a location's vertical distance ( height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height.
Overview | Global Sea Level – NASA Sea Level Change Portal
WEBGlobal mean sea level provides an integrative measure of the state of the climate system, encompassing both the ocean and cryosphere (ice covered portions of Earth), and it can be viewed as an important indicator of what is happening to the climate in the present and what may happen in the future.
Key Indicators: Global Mean Sea Level
WEBGlobal mean sea level is an important climate indicator, providing information on how the ocean is warming and how much land ice is melting. Global sea levels have been rising for decades in response to a warming climate.

Sea Level - National Geographic Society
WEBOct 19, 2023 · Vocabulary. Sea level is the base level for measuring elevation and depth on Earth. Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, currents, river discharges, and variations in gravity and temperature prevent the sea surface from being truly level.
Climate Change: Global Sea Level | NOAA Climate.gov
WEBApr 19, 2022 · Global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880. The rising water level is mostly due to a combination of melt water from glaciers and ice sheets and thermal expansion of seawater as it warms.
