Sea Level Changes and Its Effect on Groundwater

Sea level fluctuates. It dates back to the Mesozoic era - precisely Triassic Period. However, there are factors responsible for this. The most common of them is the melting of ice sheets.

There are some instances that does not involve the melting of ice sheets because prior to formation of ice sheets, Sea levels had been increasing. This can be attributed to the Earth’s Revolution and tilting. Whenever the tilt is high, the rainfall will be high especially in the higher altitudes. This in turn increases the groundwater levels

It is a usual phenomenon that sea levels impacts directly to the groundwater level. Sea level has an indirect relationship to the groundwater level. Whenever sea level increases, groundwater level decreases and vice versa.

Also, the groundwater level has a direct relationship to the depth (and even size) of rivers and lakes. The depth of rivers and lakes to the surface in an area is usually a pointer to the water level in that area. When the groundwater level decreases, the rivers and lakes (if any) in that area will also decrease and vice versa.

It is important to note however, that Earth’s tilt plays a pivotal role in the temperature gradient usually experiences at the poles.
