Sea level sea level - Surging Seas: Sea level rise analysis by Climate Central

MSL is a type of standardised geodetic reference point. It is used, for example, as a chart datum in cartography and marine navigation . In aviation it is the standard sea level at which atmospheric pressure is measured. This is used to calibrate altitude , which influences aircraft flight levels . A common mean sea-level standard is the midpoint between a mean low and mean high tide at a particular place. [1]

body of water on the border between Israel and Jordan; the lowest point within land (400 meters, or 1,312 feet, below sea level).

Sea level is primarily measured using tide stations and satellite laser altimeters . Tide stations around the globe tell us what is happening at a local level—the height of the water as measured along the coast relative to a specific point on land. Satellite measurements provide us with the average height of the entire ocean. Taken together, these tools tell us how our ocean sea levels are changing over time.
