  2. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.

    The levelized cost of electricity (LCOE) is a measure of the average net present cost of electricity generation for a generator over its lifetime. It is used for investment planning and to compare different methods of electricity generation on a consistent basis.

  5. Trophic state index - Wikipedia

    en.wikipedia.org/wiki/Trophic_state_index

    The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. [1] Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1]

    Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .
