Sea level

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.Mean sea level is the average height of the ocean''s surface used as a standard in reckoning land elevation. To an operator of a tide gauge, MSL means the "still water level" the level of the sea with motions such as wind waves averaged out averaged over a period of time such that changes in sea level, e.g., due to the tides, also get averaged out. One measures the values of MSL in respect to the land. Hence a change in MSL can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates.

Klappentext

Mean sea level is the average height of the ocean's surface used as a standard in reckoning land elevation. To an operator of a tide gauge, MSL means the "still water level"-the level of the sea with motions such as wind waves averaged out-averaged over a period of time such that changes in sea level, e.g., due to the tides, also get averaged out. One measures the values of MSL in respect to the land. Hence a change in MSL can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates.
