The eustatic sea level is the distance from the center of the earth to the sea surface, the sea level change of the volume of Earth’s oceans, imagining a giant bathtube where whatever event -tectonics, continental rise or subsidence- can have a significant effect on eustatic level.   
 An increase of the eustatic sea level can be generated by.
a. Changes in the size of the ocean basin, e.g.  by tectonic seafloor spreading
b. Changes in total ocean water mass, e.g. by ice sheet runoff
c. Density changes of the water, e.g. by thermal expansion
