Physical Oceanography Physical oceanography requires a basic understanding of the mechanics of fluids. Oceans are influenced by many physical features, such as waves, currents, and tides. Waves are produced by wind, sea craft, earth movements, and exhibit physical features such as height, wave length, crest and troughs.
Currents exist as surface currents and vertical currents.
Surface currents are produced by wind and can be either cold such as the Labrador current or warm like the gulf stream. Vertical currents are produced by water density difference, but both types influence our climate. Neap Tides are produced. When aligned with earth, produce Spring Tides.
