  2. DayCent - Wikipedia

    en.wikipedia.org/wiki/DAYCENT

    Model outputs include daily fluxes of various N-gas species (e.g., N 2 O, NO x, N 2); daily CO 2 flux from heterotrophic soil respiration; soil organic C and N; net primary productivity; daily water and nitrate (NO 3) leaching, and other ecosystem parameters. Daycent has been tested using data from various native and managed systems.

  5. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...

  7. Jelly-falls - Wikipedia

    en.wikipedia.org/wiki/Jelly-falls

    A mass deposition of Pyrosoma atlanticum carcasses were found along an oil pipeline in West Africa in 2006.. Jelly-falls are marine carbon cycling events whereby gelatinous zooplankton, primarily cnidarians, sink to the seafloor and enhance carbon and nitrogen fluxes via rapidly sinking particulate organic matter. [1]

  8. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    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.

  9. Nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_cycle

    The nitrogen cycle is of particular interest to ecologists because nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition. Human activities such as fossil fuel combustion, use of artificial nitrogen fertilizers, and release of nitrogen in wastewater have dramatically altered the ...
