Sea level is generally used to refer to mean sea level (MSL), an average level for the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datum – a standardised geodetic reference point – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location.
Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, and sea level rise has been widely quoted as evidence of ongoing global warming.
The term above sea level generally refers to above mean sea level (AMSL).

Dr Matthew Wadey, University of Southampton speaks about how we measure sea level.
The global mean level of the oceans is one of the most important indicators of climate change. It incorporates the reactions from severaldifferent components of the climate system. Precise monitoring of changes in the mean level of the oceans, particularly through the use of altimetry satellites, is vitally important, for understanding not just the climate but also the socioeconomic consequences of any rise in sea level. http://www.aviso.altimetry.fr/msl
This video introduces an MSL/Geoid selection issue in GPS Pathfinder Office and demonstrates how to resolve it.
The animation shows the global mean sea level variations between 1993 and 2013 with a trend of +2.8 mm/year. Sea level anomalies from multi-mission satellite altimetry were used for the estimation of the regional mean sea level.

The Sea Level Datum of 1929 was the vertical control datum established for vertical control surveying in the United States of America by the General Adjustment of 1929. The datum was used to measure elevation above, and depression below, mean sea level. Mean sea level was measured at 26 tide gauges: 21 in the United States and 5 in Canada. The datum was defined by the observed heights of mean sea level at the 26 tide gauges and by the set of elevations of all bench marks resulting from the adjustment. The adjustment required a total of 66,315 miles of leveling with 246 closed circuits and 25 circuits at sea level. This video is targeted to blind users.

Miami, New Orleans and New York City completely under water it's a very real possibility if sea levels continue to rise. In Earth Under Water we'll see these events unfold as leading experts forecast how mankind will be impacted if global warming continues. They'll break down the science behind these predictions and explore ways humanity could adapt, including engineering vast dams near San Francisco, or building floating cities outside of New York.

Original air date: Aug. 26 at 9:30 a.m. PT (12:30 p.m. ET, 1630 UTC) NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will rise. The panelists for this briefing were: -- Michael Freilich, director of NASA's Earth Science Division at the agency's headquarters in Washington -- Steve Nerem, lead for NASA's Sea Level Change Team at the University of Colorado at Boulder -- Josh Willis, oceanographer at NASA's Jet Propulsion Laboratory in Pasadena, California -- Eric Rignot, glaciologist at the University of California, Irvine and JPL
Hangout Discussion de-convoluting horizon curvature vs curvature witnessed in these videos: - https://youtu.be/kmX8mkxX5Ic?t=4h35m Electric transmission pylons trace out the curve of the Earth as they cross Lake Pontchartrain. The tall tower (GPS: 30°17'37.59"N, 90°18'38.64”W) is listed in FAA Obstacle data under the reference number ORS# 22-001038 which provides the height of the tower at 210ft (above ground level) and 211ft (above mean sea level). The tower is ~15.9 miles from the observer. A rough, but pretty good estimate of the observer height is around 30-50ft. Given this information we'd expect to see 170 - 190ft of the tower above the horizon, which is consistent with these observations. Based on the shadows of the short towers compared to the shadows of the tall tower in google...
