Natural selection selects for individuals that compete less. Currents can be broken down into two forms of circulation. These cold patches are what remains of the subsurface "engine" of the La Nina, now starting to turn off slowly as warmer waters move in. Most of the sunlight absorbed by water on Earths surface gets stored in our oceans as heat, and heat from the atmosphere is also absorbed by the ocean, which increases the oceans temperature.

Thermohaline circulation occurs because winds move warm surface waters from the equator towards the poles, where the water cools and increases in density. The movement of air masses brings us our daily weather, and long-term patterns in circulation determine regional climate and ecosystems. Since 86% of global evaporation and 78% of global precipitation occur over the ocean, ocean surface salinity is the key variable for understanding how fresh water input and output affects ocean dynamics. While this model does not depict the ocean circulation patterns that results from atmospheric wind and density differences in water masses, it summarizes the key concepts involved in explaining this process. 0 & 1 & 2 b.
