Recognize the difference in ocean waves. Define fetch and Differentiate between sea ice and land ice.

Man is in a unique position with regard to Earths atmosphere and the oceans. He lives at the bottom of one and at the top of the other. The atmosphere is an ocean of air, and the seas, an ocean of water. In many respects, the atmosphere and the oceans are similar. For example, there are air currents and ocean currents, atmospheric waves (long and short) and ocean waves, and the land (terrain) beneath the sea is much like that beneath the atmosphere.

Since the oceans of air and water interface and each has a definite impact on the other, lets begin at the point of interface (the surface) and work down.

Learning Objective: Recognize the difference between wind waves, swell waves, combined waves, and rogue or freak waves, and define fetch and steady state.
