	Sea level - Wikipedia, the free encyclopedia
		In a state of rest or absence of external forces, the mean sea level would coincide with this geoid surface, being an equipotential surface of the Earth's gravity field.
		The melting of glaciers at the end of ice ages is an example of eustatic sea level rise.
		The subsidence of land due to the withdrawal of groundwater is an isostatic cause of relative sea level rise.

	Above mean sea level - Wikipedia, the free encyclopedia
		The height above average terrain (HAAT) for a station is determined from topographic maps by averaging the elevation AMSL at points along several radials or radii.
		It should be noted that the concept of a "mean sea level" is in itself rather artificial, because it is not possible to determine a figure for mean sea level for the entire planet, and it varies quite a lot even on a much smaller scale.
		For example, the Ordnance Survey uses a height datum based on the mean sea level of a particular gauge at Newlyn, Cornwall for their maps of Great Britain, and this datum is actually some 80cm different from the mean sea level reading obtained on the other side of the country.

	Articles - Sea level rise (Site not responding. Last check: 2007-11-05)
		Local âMean sea levelâ (LMSL) is defined as the height of the sea with respect to a land benchmark, averaged over a period of time, such as a month or a year, long enough that fluctuations caused by waves and tides are largely removed.
		The estimated rate of sea level rise from anthropogenic climate change from 1910 to 1990 (from modelling studies of thermal expansion, glaciers and ice sheets) ranges from 0.3 to 0.8 mm/yr.
		A common perception is that the rate of sea level rise should have accelerated during the latter half of the 20th century.

	HA 730-N Hawaii Regional Summary text
		Kauai is about 5,200 feet above sea level in its central part, but from the base of the mountains shoreward, large areas of the island are less than 1,000 feet above sea level in the southern, eastern, and northern parts.
		The regional movement of fresh ground water is from interior areas toward the ocean, and all of the water discharges diffusely to the ocean or at springs near sea level.
		Ground-water levels generally are highest in the winter months because of greater rainfall and reduced demand for ground water, and decline during the summer months when demand for ground water is greatest.

	A Primer on glacio-eustatic sea levels
		The hydrologic cycle is the constant circulation of water from the sea through the atmosphere, to the land, and its eventual return to the sea.
		Because of glacial fluctuations true, or eustatic, sea level (which those of us who live along oceanic coasts may think of as a constant, ignoring waves, tides, and storms) varies across spans of observation ranging from decades to hundreds of thousands of years.
		This variation, in turn, is superimposed on sea level fluctuations across millions of years caused by changes in the volume of the ocean basins.

	PSMSL - Frequently Asked Questions
		The sea level itself can change (sea level is believed to have increased by between 10 and 20 cm during the last 100 years) and land levels can change due to geological reasons.
		Sea level is about 20 cm higher on the Pacific side than the Atlantic due to the water being less dense on average on the Pacific side and due to the prevailing weather and ocean conditions.
		Global-average sea level is believed to have risen by between 10-20 cm during the past century and best estimates are that it will rise by approximately 50 cm in the next 100 years (i.e.

		In fact, many laypersons and scientists have asked: "Is the sea level changing, or is it the land that is moving?" That is a difficult question to answer completely, and is the subject of much ongoing research.
		As sea level rise against a coast of tough, glacially smoothed rocks, erosion is very slow, and shoreline changes are primarily produced by gradual rising.
		Depending on the rate of input of carbon dioxide, predicted sea levels range from a low of 0.5 m (1.6 ft) to a high of 3.5 m (11.5 ft!) above present by the year 2100.

		Since atmospheric pressure was 1024 mb on the day I did it, thus depressing sea level by nearly 10 cm, I subtracted that 10 cm from the 40 cm visual height to arrive at a figure of 30 cm for the adjusted height.
		That means their sea level rise would have been swimming uphill against global cooling and rising land, a physical impossibility given the climatic circumstances and the available evidence.

	High Altitude Cooking
		At sea level, the atmosphere presses on a square inch of surface with a weight of 14.7 pounds, at 5,000 ft with 12.3 pounds, and at 10,000 feet with only 10.2 pounds- a decrease of about 1/2 pound per 1,000 feet.
		Above 5,000 feet, temperatures obtained with a double boiler are not high enough for maximum gelatinization of starch.
		Above that, decreased atmospheric pressure may result in excessive rising, which stretches the cell structure of the cake, making the texture coarse, or breaks the cells, causing the cake to fall.

	Sea Level Pressure (Site not responding. Last check: 2007-11-05)
		The pressure measured at each weather station is adjusted to the corresponding temperature at sea level in order to monitor properly horizontal changes in pressure.
		For any site above sea level, this adjustment is performed by assuming that a column of air, with a particular temperature profile, exists between the stations elevation and sea level.
		Using this temperature profile, the conversion to sea level pressure is calculated by increasing the station pressure by 10 millibars for every 100 m of elevation.

	Sea level
		Mean sea level (MSL) at a given point is the average of that level when one has taken into account such things as tides and wave action.
		Mean sea level at the Pacific end of the Panama Canal is 20cm higher than at the Atlantic end.
		Over an extended period mean sea level will be affected by global warming in at least two ways: the run-off from melting glaciers on land, and the increased volume reflecting the coefficient of expansion of water.

	Sea Level Change Resources
		Half of observed sea level rise in N. Sea is eustatic, and is result of melting ice (glacial eustatism), some is due to warming of water causing an increase in volume.
		Rising sea levels tend to lead to renewed erosion, and cliffs which had been rendered inactive by falling levels are attacked again.
		At the same time, global sea levels are rising and this rise is expected to accelerate significantly during this Century due to anthropogenic global warming.

	How high is Mauna Loa above sea level?
		Lieutenant James King, on Cook's 1779 voyage, first calculated the elevation as 16,020 feet (4883 m), based on vertical angles to its summit from sea level.
		Level lines from Hilo to Volcano House run in 1912 and 1921 showed that the entire summit of Kilauea had increased in elevation by as much as 3 m (10 feet).
		Uplift of Mauna Loa, determined by level surveys in its summit area from 1977 to 1981, was at least 13 cm (5 inches), and subsidence related to the 1984 eruption was at least 61 cm (2 feet).

		In many cases, the results are as sensitive to uncertainty regarding geological processes as to the rate of sea level rise.

		They were formed at sea level and, even though eustatic sea level has risen, they have risen far more from isostasy.
		The northern Baltic Sea is rising nearly one centimeter a year.
