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.
The eustatic (global) sea level is the volume of Earth's oceans.
[4] Eustatic sea level is not relative to local surfaces, because relative sea level depends on many factors – including tectonics, continental rise and subsidence.
Differences in eustatic sea level over time stem from three main factors:
