Something on land can be measured as below sea level when its elevation is lower than the average level of the world's oceans. This can be determined using a reference point, such as sea level, to calculate the vertical distance below it. Topographic maps and GPS technology are commonly used to measure elevations above and below sea level.
A region at or below sea level is called a "low-lying area" or a "depression."
This type of map is called a bathymetric map. It measures the different levels below the sea level. It is like a topographic map but below sea level.
New Orleans in Louisiana, USA is a city that sits below sea level.
40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.
The Dead Sea is at an altitude of 423m below sea level.add The Salton Sea in US is 69m below seal level.
if the land surrounding the sea is below sea level
If you are talking about dry land that is below sea level, then these are a few examples... The Netherlands (formerly called Holland) Southern Louisiana If you are talking about seas or oceans, then it's just about all if not all of them. Sea level is basically the top of the water, like where the water level meets the shore. Anything below that is below sea level. If it is a lake or a pond, then it may vary. Because the level of the land may also be above or below sea level depending on the location.
Yes, that is correct. Altitude above sea level, for example, is negative or positive - if you are below sea level, a negative number will be used.
The height above or below sea level is "elevation". Altitude is used only for distance above sea level.
above sea level
14.7 psi = sea level. 15.2 psi = 1671 ft below sea level
