Eustatic sea level

The eustatic sea level (from Greek εὖ eû, "good" and στάσις stásis, "standing") is the distance from the center of the Earth to the sea surface.^[1][2] An increase of the eustatic sea level can be generated by decreasing glaciation, increasing spreading rates of the mid-ocean ridges or increasing the number of mid-oceanic ridges. Conversely, increasing glaciation, decreasing spreading rates or fewer mid-ocean ridges can lead to a fall in the eustatic sea level.

Changes in the eustatic sea level lead to changes in accommodation and therefore affect the deposition of sediments in marine environments.
