Nautical Term: MSL
Definition of MSL
Mean Sea Level (MSL) refers to the average height of the sea surface, measured over a long period of time. This value is crucial for various marine activities, such as harbor and shipping operations, where accurate determination of the water level is essential.
For instance, in the context of harbor operations, knowing the Mean Sea Level is crucial for managing the flow of water and the movement of ships. By using precise data on Mean Sea Level, harbor authorities can ensure that the water depth remains suitable for navigation, thereby minimizing the risk of accidents and improving overall operational efficiency.
