The major disciplines of oceanography are geological oceanography, physical oceanography and chemical oceanography. Oceanographers and others involved in these disciplines often work together to unravel the mysteries and unknowns of ocean science. In reading about each of these sub-fields, keep in mind that some of the most important
Physical oceanography is a sub-discipline of oceanography that involves the study of waves, tides, and currents; the ocean-atmosphere relationship that influences weather and climate; and the transmission of light and sound in the oceans. The scales of these processes range through spatial scales from centimeters to global and time scales from seconds to centuries.
