MEAN SEA LEVELS Meaning and
Definition
-
Mean sea level refers to the average height of the ocean's surface at a given location over a specific period of time. It is a measurement that seeks to determine a consistent and reliable reference point to assess changes in sea levels. This value is calculated by taking numerous tidal and atmospheric conditions into account to establish a long-term average, typically over several years.
Mean sea level serves as an essential tool for various purposes, particularly in coastal engineering, climate research, and navigation. By establishing a median level of the sea surface, it allows scientists and researchers to study and monitor the changes in the earth's climate, including the effects of global warming and sea-level rise. These measurements help to identify potential risks and determine the impacts on coastal areas, providing valuable data for developing climate change adaptation and mitigation strategies.
Determining mean sea level involves the use of tidal gauges and satellite altimetry, among other technologies. Tidal gauges record the water levels at specific coastal stations, while satellite altimetry measures the distance between the satellite and the ocean's surface. These records are then combined, taking into account factors such as tides, currents, and atmospheric pressure variations, to calculate an accurate average sea level.
Mean sea level serves as a crucial benchmark for understanding the dynamics of our planet's oceans, including their connection to climate change. It allows researchers to detect long-term trends and variations in global sea levels, playing a vital role in addressing the challenges posed by rising oceans in the modern world.
