  2. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    The six aforementioned elements are used by organisms in a variety of ways. Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins.

  3. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    Hydrogen and oxygen are found in water and organic molecules, both of which are essential to life. Carbon is found in all organic molecules, whereas nitrogen is an important component of nucleic acids and proteins. Phosphorus is used to make nucleic acids and the phospholipids that comprise biological membranes. Sulfur is critical to the three ...

  4. Carbon-based life - Wikipedia

    en.wikipedia.org/wiki/Carbon-based_life

    Liquid water is essential for carbon-based life. Chemical bonding of carbon molecules requires liquid water. [30] Water has the chemical property to make compound-solvent pairing. [31] Water provides the reversible hydration of carbon dioxide. Hydration of carbon dioxide is needed in carbon-based life. All life on Earth uses the same ...

  5. Biological pump - Wikipedia

    en.wikipedia.org/wiki/Biological_pump

    The biological pump depends on the fraction of primary produced organic matter that survives degradation in the euphotic zone and that is exported from surface water to the ocean interior, where it is mineralized to inorganic carbon, with the result that carbon is transported against the gradient of dissolved inorganic carbon (DIC) from the ...

  6. Oceanic carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Oceanic_carbon_cycle

    The total carbon transport of rivers represents approximately 0.02% of the total carbon in the atmosphere. [41] Though it seems small, over long time scales (1000 to 10,000 years) the carbon that enters rivers (and therefore does not enter the atmosphere) serves as a stabilizing feedback for greenhouse warming. [42]

  7. Marine life - Wikipedia

    en.wikipedia.org/wiki/Marine_life

    Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...

  8. Total inorganic carbon - Wikipedia

    en.wikipedia.org/wiki/Total_inorganic_carbon

    The aquatic inorganic carbon system is composed of the various ionic, dissolved, solid, and/or gaseous forms of carbon dioxide in water. These species include dissolved carbon dioxide, carbonic acid, bicarbonate anion, carbonate anion, calcium carbonate, magnesium carbonate, and others. The relative amounts of each species in a body of water ...

  9. Marine reservoir effect - Wikipedia

    en.wikipedia.org/wiki/Marine_reservoir_effect

    After making the clay vessel fish was prepared in the vessel over a fire. The archaeologists made sure some of the fish stuck to the pot. The pot and some of the burnt crust at the bottom were tested which showed a Carbon-14 14 C age of 700 years old. Felix Riede estimated at the time the use of the Carbon-14 method maybe off by 2,000 years. [4]
