Estimating How Much Sea Level Changes when
... At times during the Quaternary Period (approximately the last 2 million years of Earth history), glaciers were much more extensive than they are now. The world’s ocean was the source of the glacial ice, and so sea level was significantly lower when the additional ice was present. As Earth still has ...

Physical oceanography
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanographies.
