  2. Marine biogenic calcification - Wikipedia

    en.wikipedia.org/wiki/Marine_biogenic_calcification

    This series of reactions governs the pH levels in the ocean and also dictates the saturation state of seawater, indicating how saturated or unsaturated the seawater is with carbonate ions. Consequently, the saturation state significantly influences the balance between the dissolution and calcification processes in marine biogenic calcifiers.

  3. Saturation mutagenesis - Wikipedia

    en.wikipedia.org/wiki/Saturation_mutagenesis

    Saturation mutagenesis is commonly achieved by site-directed mutagenesis PCR with a randomised codon in the primers (e.g. SeSaM) [2] or by artificial gene synthesis, with a mixture of synthesis nucleotides used at the codons to be randomised. [3] Different degenerate codons can be used to encode sets of amino acids. [1]

  4. Oxygen minimum zone - Wikipedia

    en.wikipedia.org/wiki/Oxygen_minimum_zone

    In OMZs oxygen concentration drops to levels <10 nM at the base of the oxycline and can remain anoxic for over 700 m depth. [7] This lack of oxygen can be reinforced or increased due to physical processes changing oxygen supply such as eddy-driven advection, [7] sluggish ventilation, [8] increases in ocean stratification, and increases in ocean temperature which reduces oxygen solubility.

  5. Lysocline - Wikipedia

    en.wikipedia.org/wiki/Lysocline

    The lysocline is the depth in the ocean dependent upon the carbonate compensation depth (CCD), usually around 5 km, below which the rate of dissolution of calcite increases dramatically because of a pressure effect. While the lysocline is the upper bound of this transition zone of calcite saturation, the CCD is the lower bound of this zone. [1]

  6. Saturation diving - Wikipedia

    en.wikipedia.org/wiki/Saturation_diving

    The "saturation system", "saturation complex" or "saturation spread" typically comprises either an underwater habitat or a surface complex which includesof a living chamber, transfer chamber and submersible decompression chamber, [45] which is commonly referred to in commercial diving and military diving as the diving bell, [46] personnel ...

  7. Biological oceanography - Wikipedia

    en.wikipedia.org/wiki/Biological_oceanography

    Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system.Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.

  8. Library (biology) - Wikipedia

    en.wikipedia.org/wiki/Library_(biology)

    Site saturation substitutes each of the 20 possible amino acids (or some subset of them) at a single position, one-by-one. In molecular biology, a library is a collection of genetic material fragments that are stored and propagated in a population of microbes through the process of molecular cloning.

  9. Underwater habitat - Wikipedia

    en.wikipedia.org/wiki/Underwater_habitat

    The deep cabin was also an early effort in saturation diving, in which the aquanauts' body tissues were allowed to become totally saturated by the helium in the breathing mixture, a result of breathing the gases under pressure. The necessary decompression from saturation was accelerated by using oxygen enriched breathing gases.
