Where does the ocean’s nutrients come from?

The ocean is an important source of renewable natural resources. These materials are natural resources that are renewable even though they are used over and over again. As the ocean is the primary source and source of these resources. For this reason, even though they have been used since ancient times, it has not ended, nor does it create any imbalance in the nutrition, salts and environment, the most important reason of which is the natural biological and chemical factors that efficiency, causing the amount of nutrients separated from the seawater to be reabsorbed, resulting in a natural balance between them.

Due to the presence of renewable resources (some non-renewable resources are also present) in the ocean, they have been used over and over again since the beginning of time, as the ocean has the status of a storage structure, in which different types of Nutrients and salts exist in both soluble and insoluble forms, which was believed centuries ago to have been present in the oceans throughout the geological period, from the Perli-Casperian and Paleozoic to the present day. Aquatic resources and composition are completely unchanged, but this information was not clear in the early “Pearly Caspian” period, because 2500 million years ago oxygen and organic life were different, but between 1873-76 “Oceanography” When science came out, the fact came to light that despite the fact that the inclusion and separation of elements in the sea is at a high speed, the balance of nutrients and salts in the environment is still maintained, which is due to a strong supply system and Biochemical interactions are called homogeneity. The river is the most important source of supply system in the sea.

Which continues to deliver nutrients and salts to the ocean through various chemical and biological decomposition processes. Even through evaporation, pure water continues to be added back to the ocean along with dissolved ions. The total amount of nutrients and salts added from these sources is estimated at 20 million tons annually.

It is quite possible that in the past there was a decrease in the supply of nutrients and salts, but due to the growth of terrestrial vegetation and increased productivity, the amount of “humic acid” (humic acid) increased, which chemical elements. (especially since the Devonian period). During the Upper Cretaceous period, the sea level rose and expanded, causing the land areas to narrow and Because of this, nutrients and inclusions also decreased. This behavior reveals two aspects of inclusion. First, chemicals and nutrients are added to the water, then they dissolve in the water under chemical and biological interaction and become an integral part of the open sea water. The cells are formed, after which they are separated from the sea water.

For example, during “adsorption” (adsorption), when the effect of this chemical process takes place, its supply is in the sea water, when this mineral enters the sea water, the cause of “adsorption” or ion exchange. is converted into a fast electron. For example, cation (Cation) binding occurs with minerals.

In this situation, one mineral or element separates from another by “adsorption” or ion exchange, which depends mostly on the levels of “ion potential” and “hydration”. Is. Because sodium is highly “hydrated”. For this reason, it tends to be highly hydrated while potassium is highly “hydrated” and easily adsorbed with minerals and rapidly dissociates from seawater.

Organic matter is also an important mechanism for adding nutrients and salinity to the ocean. Microorganisms create their own internal chemical environment and use their energy to regulate auxiliaries that are not normally stable in seawater. Carbonate precipitates such as foraminifera, mossa mineral “aragonite” or lexate even when the water is cold and unsaturated with respect to these minerals.

Diatom (Diatom) is very suitable for silica grinding. While seawater near the “photozone” typically decreases rapidly relative to supply. The process of decay of organisms begins soon after their life cycle is completed and organic organisms are subjected to the “degradation” process. If the water is non-condensable, for example, diatoms dissolve 99.99 percent before reaching the deep parts of the ocean. That is, if those minerals are not present in saturated condition in the sea water, from which they are formed, the shells also dissolve in it.

Some of them are stored in sediments. Decomposing organisms found in surface water use carbon dioxide and produce organic matter with oxygen. It raises the pH. Therefore, carbonates remain stable or dissolve slowly in hot water. But as temperature decreases with depth, carbon dioxide is under pressure, which causes carbon dioxide solubility to increase with depth, but below the “photozone.” Oxygen is used.

while carbon dioxide and nutrients are released. The depth at which carbonate solubility increases relatively rapidly. It is called “Isocline”. Where the solution rate becomes higher than the carbonate precipitation rate, it is called the Carbonate Compensation Depth. This process of dissolution releases nutrients. Which come to the sea level through upwelling of water. Which usually contain nitrogen, phosphorus etc.

In this way, salts and nutrients are added to the sea water. Which is used again and again by the names. Annual biological productivity in the ocean from these sources is relatively many times higher than on land. Even a small fraction of the organic production stored in the sediments of marine reefs separates and provides nutrients, but more food and nutrients are added from land via rivers, which are of course abundant in quantity.

One thing to remember here is that nutrients cannot enter the ocean until the sediments are brought up from the water and subjected to the biological, chemical and physical interactions of erosion and weathering. The amount of inorganic product that settles in the sediment is calculated after dividing the production rate by the dissolution rate. Authegenic minerals also separate elements from seawater. The most important in this regard are zeolites, which develop where the sea contains high silicate or aluminum elements.

Especially igneous minerals (glass) but modern research has further clarified the fact that biological and chemical deposition alone is not sufficient to maintain the nutrient supply and balance in the ocean, but some terrestrial biological and chemical interactions with seamounts. (Spreading Ridges) have also been discovered, as the heat released from the basalt passes over the sea ridges. In this situation, the seawater interacts with the hot basalt. Since seawater contains sulfur, it causes the precipitation of metals that dissolve from the “basalt” in the form of sulfides. For example, iron sulfide and copper sulfide.
