Domain-specific

• Biological Pump
  • The biological pump is the suite of biological and gravitational processes by which carbon fixed in the sunlit surface ocean is transferred downward into the deep ocean and ultimately into sediments, maintaining a vertical gradient in dissolved inorganic carbon (DIC) that keeps atmospheric CO₂ roughly 200 ppm lower than it would be in the pump's absence

    This sourceThe surface-to-deep DIC gradient the pump maintains and the magnitude of the atmospheric CO2 drawdown attributable to it.

• Carbonate Saturation State
  • In the vertical structure of the ocean this produces two depth surfaces — the aragonite saturation horizon, shallower, and the calcite compensation depth (CCD), deeper — below which each mineral dissolves, with the CCD typically sitting at 4–5 km in the modern Atlantic but shallower in the Pacific and in regions of high organic-matter respiration
• Upwelling
  • The replacement water, which has been sequestered from sunlight for months to years at depth, carries high concentrations of nitrate, phosphate, silicate, and dissolved CO₂ accumulated from the remineralization of sinking organic matter

    This sourceDeep-water enrichment in nitrate, phosphate, silicate and dissolved inorganic carbon produced by remineralization of sinking organic matter.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 3 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
