<ul><li><p>Ocean Water Chemistry and Currents</p></li><li><p>Ocean Water ChemistrySalinity: the amount of salt dissolved in ocean water1kg of ocean water contains 35g of salt.Ocean contains many different kinds of salts</p></li><li><p>Differences in SalinityLower salinity near the surface because of rain, rivers, etc.Hot climates cause evaporation which makes water saltier (ex. Red Sea)Saltier near the poles (salt is left behind when water freezes)</p></li><li><p>Temperature of Ocean WaterTemperatures vary with locationTemperature is warmer near the surface**Temperature drops and pressure increases as you go deeper underwater!!Cold WaterWarm WaterCold WaterWarm WaterCold Water</p></li><li><p>CurrentsCurrents are a river of water within the oceanThere are two types of currents:Surface Currents 2. Deep Currents</p></li><li><p>Surface CurrentsEx. Gulf streamSeveral hundred meters deepWarm surface currents can effect climate by warming or cooling the air above it.Influenced by the coriolus effectMove clockwise in the northern hemisphereMove counter clockwise in the southern hemisphere.Surface Currents move horizontally!! </p></li><li><p>Surface Currents</p></li><li><p>Deep CurrentsCaused by differences in densityCold water rises as it is heated, warm water sinks as it coolsSalty water sinks, less salty water risesWarm Water and Less Salty WaterCold Water and More Salty WaterDeep currents move vertically!!</p></li><li><p>El NinoOccurs every 2-7 yearsWinds form over the western PacificWarm water moves east.</p></li></ul>
