Sea level, an Uncommon card

The card carries these facts from its Wikipedia article.

• The global MSL is a type of vertical datum – a standardised geodetic datum – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels.
• A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location.
• The term above sea level generally refers to the height above mean sea level.
