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.
