These processes affect the transport of water, heat, salinity, nutrients and carbon in the ocean, impacting on the climate system by modifying it's ability to absorb human - emitted carbon dioxide and excess heat resulting from increased carbon dioxide concentrations.

Density currents are also caused by differences in the amount of salt (salinity) on the ocean water.

The principal scientific objective is to make global SSS measurements over the ice - free oceans with 150 - km spatial resolution, and to achieve a measurement error less than 0.2 (PSS - 78 [practical salinity scale of 1978]-RRB- on a 30 - day time scale, taking into account all sensors and geophysical random errors and biases.Salinity is indeed a key indicator of the strength of the hydrologic cycle because it tracks the differences created by varying evaporation and precipitation, runoff, and ice processes.

Ocean water density depends on its temperature and its salinity.

Salinity changes within the ocean also have a significant impact on the local density and thus local sea level, but have little effect on global average sea level change.

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiOcean, having disastrous effects on marine life and fishing

The key to this model lies in the distribution of precipitation on Earth, with maxima in the tropics and in high latitudes, so that the Arctic receives an excess of precipitation over evaporation of about one third, which is associated with the permanent presence of the low salinity surface water mass of the Arctic Ocean, separated by a halocline from the saltier Atlantic water below.

It, too has significant transverse structure and is a global transporter of heat as complex currents move water around based on its temperature, salinity / density, wind direction at the surface, heat sources at depth, evaporation, the coriolis force, the shape of the ocean bottom, and freshwater contributions from e.g. rivers and melting ice.
