This chapter explores Oceans and their atmospheric interactions. Ocean currents are the continuous, predictable and directional movement of seawater driven by gravity, wind and water density. There are two basic types of currents- surface and deep-water currents that help define the character and flow of ocean water across Earth. The chapter explains the effects of ocean current and technical terms like the specific heat capacity or the amount of heat energy required to raise the temperature of a substance per unit of mass.

El Nino and La Nina that translates to ‘The Little Boy’ and ‘The Little Girl’ in Spanish are the climate patterns in the Pacific Ocean that can affect weather worldwide. While the management of the impact of El Nino and La Nina has been very difficult in the past, there are now sensors across the Pacific Ocean that predict the effects of these events in advance. The chapter then discusses hurricanes and tropical cyclone formations, and the impact of hurricanes on the weather and economy. A case study of Typhoon Haiyan is provided to link concepts to real life events around us. Finally there is an introduction about ocean acidification, its causes and how humans can stop ocean acidification.
