  1. Sea level - Wikipedia

    Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to the average sea level datum.It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (MSL) (contrast with flight level), and in the atmospheric sciences, and land surveying.

  3. Sea Level (band) - Wikipedia

    Sea Level was an American jazz fusion band from Macon, Georgia that mixed jazz, blues and rock and existed between 1976 and 1981. Initially it was an offshoot of The Allman Brothers Band, but as tensions grew between the loss of two of its founding members and personal grievances between Gregg Allman and other bandmates and associates, Sea Level took on a life of its own as an independent band.

  4. Sea level rise - Wikipedia

    The average global sea level rise began around the start of the 20th century. Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century.

  5. 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. In aviation it is the standard sea level at which atmospheric ...

    • Geological influences

    Global or eustatic sea level has fluctuated significantly over Earth's history. The main factors affecting sea level are the amount and volume of available water and the shape and volume of the ocean basins. The primary influences on water volume are the temperature of the seawater, which affects density, and the amounts of water retained in other reservoirs like rivers, aquifers, lakes, glaciers, polar ice caps and sea ice. Over geological timescales, changes in the shape of the oceanic basins

    Each year about 8 mm of water from the entire surface of the oceans falls onto the Antarctica and Greenland ice sheets as snowfall. If no ice returned to the oceans, sea level would drop 8 mm every year. To a first approximation, the same amount of water appeared to return to the ocean in icebergs and from ice melting at the edges. Scientists previously had estimated which is greater, ice going in or coming out, called the mass balance, important because it causes changes in global sea level. Hi

    Sea level has changed over geologic time. As the graph shows, sea level today is very near the lowest level ever attained. During the most recent ice age the world's sea level was about 130 m lower than today, due to the large amount of sea water that had evaporated and been depo

  7. Sea - Wikipedia

    At the last glacial maximum, some 20,000 years ago, the sea level was 120 metres (390 ft) below its present-day level. For at least the last 100 years, sea level has been rising at an average rate of about 1.8 millimetres (0.071 in) per year.

  9. Sea-level curve - Wikipedia

    Their sea-level curve was based on seismic and biostratigraphic data accumulated during petroleum exploration. [1] The Vail curve (and the monograph itself) was the subject of debate among geologists, because it was based on undisclosed commercially confidential stratigraphic data, and hence not independently verifiable.

  11. Atmospheric pressure - Wikipedia

    This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea-level for locations above or below sea-level. The average pressure at mean sea-level in the International Standard Atmosphere is 1013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
