For media enquiries, please contact our corporate media office. a. number of species Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. More saline water masses are found in areas where there is a lot of evaporation because salt is left in the water, or in polar areas because as ice forms, salt is left in the water. They also affect the routes taken by ships as they carry goods and people across the sea. Because of their size, small isolated islands accumulate more species by chance. e. desert, When logging is carried out in a watershed, a likely effect on the local streams is Currents like the Atlantic Oceans Gulf Stream are highways for marine life, ushers of heat, and drivers of storms. e. suppressed thermocline in the Pacific Ocean, All of the following are examples of non-point source water pollution EXCEPT It underlies central Florida and is contaminated by pesticide and fertilizer runoff from farms. The carbon dioxide concentration in the atmosphere is reduced by cutting trees Surface Ocean Circulation | EARTH 103: Earth in the Future e. Nitrous oxide. c. The warming of the western pacific causes a reduction in upwelling nutrients and an increase in rainfall For example, the Gulf Stream in the Atlantic Ocean brings heat from near the equator to Europe, making it much warmer than other areas at similar latitudes. Organisms move from one layer to another, and plant and animal remains containing nutrients "rain" down, but the layers stay fairly separate in all but a few places. Environmental Protection Agency.

Rotation of the Earth on its axis The rule is simple - salt makes water heavier, so it sinks. Rise in water table Ocean circulation - Understanding Global Change Differences in temperature and salt content of the water cause some areas of water to sink and some areas of water to rise. Viewed from above, currents in these subtropical gyres flow in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere. Currents that move up and down in the water column, also called vertical currents, are created by differences in the density of water masses, where heavier waters sink and lighter waters rise. In tropical latitudes the ocean accounts for a third or more of the poleward heat transport . e. conservative resource, Overuse of groundwater in coastal areas would most likely result in which of the following?
