Branches of Oceanography or Marine Science

physical oceanography collect and study data on the ocean’s tides, currents, and waves. physical oceanography uses a variety of special instruments and devices that measure the earth’s magnetic and gravitational fields, the speed of sound traveling through water, the ocean’s depths, and the flow of heat from the earth’s interior. geological oceanography study of the […]

What is Oceanography?

Oceanography is the systematic study of the ocean environment on all scales and from biology to physics. It includes descriptive, quantitative, predictive, interdisciplinary science. Geological oceanography Branch of marine science that studies seafloor formations, sediments, and coastal formations Biological oceanography the study of the lifeforms in the ocean and their relationships to one another Chemical […]
