| Aviation charts are divided into boxes and the maximum terrain altitude from MSL in each box is clearly indicated. |
| Since the terrain elevation is also referenced to MSL, the pilot can estimate height above ground by subtracting the terrain altitude from the altimeter reading. |
| The careful measurement of variations in MSL can offer insights into ongoing climate change, and sea level rise has been widely quoted as evidence of ongoing global warming. |
| Other solar-system exploration programs, such as the next mission to the outer planets, are being slashed to pay for msl. |
| Prior to 1921, the datum was MSL at the Victoria Dock, Liverpool. |
| Generally, the pressure used to set the altimeter is the barometric pressure that would exist at MSL in the region being flown over. |
