Sea level change that is the result of an increase or decrease in the height of the land. When the height of the land increases, the sea level falls and when the height of the land decreases the sea level rises

• Isostatic

• Steric

• Eustatic

Changes in sea level due to total ocean water mass, for instance, by ice sheet runoff. When an ice sheet such as Greenland begins to lose its ice mass due to melt, the liquid water is transported to the ocean

• Steric

• Isostatic

• Eustatic

Sea level change due to oceans warming, density decreases due to thermal expansion and thus even at constant mass the volume of the ocean increases.
