The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air.The measurement of turbidity is a key test of both water clarity and water quality.
The calcification and dissolution of their shells causes changes both in the surface seawater carbonate chemistry, and in deep-water chemistry. [25] These organisms are excellent paleo-proxies as they record ambient water chemistry during shell formation and are well-preserved in the sedimentary fossil record.
Ocean turbidity is a measure of the amount of cloudiness or haziness in sea water caused by individual particles that are too small to be seen without magnification. Highly turbid ocean waters are those with many scattering particulates in them. In both highly absorbing and highly scattering waters, visibility into
It constitutes around 38,000 Pg C [18] and includes dissolved carbon dioxide (CO 2), bicarbonate (HCO − 3), carbonate (CO 2− 3), and carbonic acid (H 2 C O 3). The equilibrium between carbonic acid and carbonate determines the pH of the seawater. Carbon dioxide dissolves easily in water and its solubility is inversely related to temperature.
Marine primary production is the chemical synthesis in the ocean of organic compounds from atmospheric or dissolved carbon dioxide. It principally occurs through the process of photosynthesis , which uses light as its source of energy, but it also occurs through chemosynthesis , which uses the oxidation or reduction of inorganic chemical ...
Carbon dioxide is removed from the atmosphere when it dissolves in seawater and turns into carbonic acid. The acid then weathers rocks, creating bicarbonate and other ions. Calcium carbonate is a precipitate from calcium and the bicarbonate ions, while the carbon is precipitates as limestone. [1]
In the deep ocean, marine snow (also known as "ocean dandruff") is a continuous shower of mostly organic detritus falling from the upper layers of the water column.It is a significant means of exporting energy from the light-rich photic zone to the aphotic zone below, which is referred to as the biological pump.
