Seawater
The ways in which dissolved components are added and removed from seawater
The seas are the largest water reservoirs in the world. Most of the sea waters are salty. The most obvious source of these salts is the rivers. When it rains, the rain water flows on earth surfaces that may contain weathered rock material of different origins and varied mineral contents most of which are salts in nature.
These salty substances are carried down stream in to the sea.
The seas rarely have outlets that are large enough to drain the salts away. Also the evaporation rate in the sea is very high thus making the majority of the salts remain in high concentrations at the sea. Therefore, sea water will be salty for ever. Sea water may not just be compared with concentrated river water after evaporation because the river water flows constantly while the sea water is stagnant in most of the time. The concentration of different types of minerals differs with different levels of disposition of certain salt components in the sea. For example the sodium ions may be enter the sea water at a high rate of 7.9 10 12 moles within a year thus the sea has a lot of sodium with time (Swenson, n.d).
At the same time, other minerals like calcium and potassium also enter the sea at different rates that could be even higher that the sodium. At the end, the sea water holds quite a large amount of minerals than a river can hold. When sea water is evaporated, it leaves a residue evaporate comprising of complex mix of the salts. The salinity level is usually high. Some of the most common dissolved in sea water potassium, calcium, sodium, magnesium, chlorine, hydrocarbons, and sulphurous substances among others.
Nature can take its role in the replenishment of the salt level in the sea. There chemical processes that play a role in the concentration of sea water for example the hydrothermal processes found in hot springs thus affecting the chemical composition of basalt rock minerals.
Biological processes are not to be ignored since some phytoplankton that dwell in the sea play an active role in the removal of calcium to form shell that may later on be buried under the seabed. This is one way in which sea water salts are removed from the ocean. The bodies of these organisms are fed on by other sea animals. Carbon ion removal process involves biogeochemical processes result to the basic fuel formation from the sea (Fuhrman, Bell, 1995). Evaporation is also a good process through which salt material is removed from the sea since the residue deposits may form gypsum, sylvite, and salt rocks that solidify and can be taken away from the sea by mining processes.
The ocean chemistry can be affected by the interaction of pore water. The pore water material can be used up by microbes in found in the intergrain space through biological processes thus reducing sediment salts from the water. In this case many of these organisms run short of oxygen and are therefore forced to use mineral components found in the sea water for metabolism thus the overall result is reduced salt levels (Swenson, n.d).
In conclusion, researchers need to carry out more research on the processes that are involved in the addition of salt water and advice more on whether the sea water can at one time in research be salt less like some fresh water lakes of the world.
