Ch. 5 continued Global ocean salinity Pycnocline Water that increases in density by getting colder and more saline may begin to sink. This sinking is aided by o Radiational cooling o Evaporation (removes heat and increases salinity) o Ice formation Tend to produce deep water… during summer in Antarctica, and northern Atlantic in winter Water becomes dense because when water moves to higher lats.--> radiational cooling. Evaporation makes water more saline, uses a lot of heat and energy, cools water
