Eustatic sea level changes are global sea level changes related to changes in the volume of water in the ocean. These can be due to changes in the volume of glacial ice on land, thermal expansion of the water, or to changes in the shape of the seafloor caused by plate tectonic processes.

What are the causes of eustatic sea level change?

Factors that affect eustatic sea level are large scale events: tectonic activity shrinking or growing the area of world oceans, a rise in temperatures causing thermal expansion of water, or large ice sheets melting and adding water to the oceans are the three most commonly discussed.
