This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included. Places where seawater and rainwater is pumped away are included.
This is a list of countries and territories by their average elevation above sea level based on the data published by Central Intelligence Agency, [1] unless another source is cited. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.
These island countries also have the smallest range between their lowest (sea level) and highest points, and are very sensitive to changes in sea level. The highest and lowest points in China constitute the greatest elevation range within any single country at 9,002 metres (29,534 ft).
In Hong Kong, "mPD" is a surveying term meaning "metres above Principal Datum" and refers to height of 0.146 m (5.7 in) above chart datum [8] and 1.304 m (4 ft 3.3 in) below the average sea level. In France, the Marégraphe in Marseilles measures continuously the sea level since 1883 and offers the longest collated data about the sea level.
With a temperature lapse rate of −6.5 °C (-11.7 °F) per km (roughly −2 °C (-3.6 °F) per 1,000 ft), the table interpolates to the standard mean sea level values of 15 °C (59 °F) temperature, 101,325 pascals (14.6959 psi) (1 atm) pressure, and a density of 1.2250 kilograms per cubic meter (0.07647 lb/cu ft).
A below-sea-level surface pressure record of 1,081.8 hPa (31.95 inHg) was set on 21 February 1961. ... 10.3 m is the maximum height to which water can be raised using ...
The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
Sea of Galilee water levels (January 2004 – February 2012) The water level is monitored and regulated. There are three levels at which the alarm is rung: The upper red line, 208.9 m (685 ft) below sea level (BSL), where facilities on the shore start being flooded. The lower red line, 213.2 m (699 ft) BSL, where pumping should stop.
