EAS 1600 Introduction to Environmental Science Class 12 - The Oceans: Composition, Structure, Salinity We now begin our investigation of the Ocean and its role in the Earth System. Earlier we found that the atmosphere and its circulation is unable to balance the energy inputs and outputs. Even with the general circulation and the hydrologic cycle, there is an excess of energy in the tropical regions and a deficit of energy in the mid-latitudes and polar regions. Let’s see if the oceans are able to make up the difference. But first, let’s review some basic facts about the ocean... The Oceans of the World Pacific (166,241,000 sq km) Atlantic (86,557,000 sq km) Indian (73,427,000 sq km) Arctic (9,485,000 sq km) The Major Seas South China (2,974,600 sq km); Caribbean (2,515,900 sq km); Mediterranean (2,510,000 sq km); Bering (2,261,100 sq km); Gulf of Mexico (1,507,600 sq km); Sea of Okhotsk (1,392,100 sq km); Sea of Japan or East Sea (1,012,900 sq km); Hudson Bay (730,100 sq km); East China (664,600 sq km); Andaman (564,900 sq km); Black (507,900 sq km); Red (453,000 sq km) The Ocean As A Basin
