Marine water body biological carbon pump

An oceanic pathway with illuminated surface water and sufficient depth for export below the euphotic zone, not a universal marine-waterbody structure. Buoyant particles and dark carbon fixation also contribute; this graph is not a complete carbon budget. Oxygen consumption is conditional on aerobic remineralization.

  4. ADD_CAUSAL_GRAPH 2026-09-04 · codex

    Added a marine-water-body biological carbon pump graph backed by PMID:16163345, PMID:18497287, DOI:10.1038/ngeo1921, PMID:23139690, PMID:21329211, and DOI:10.3354/meps010257.

  5. UPDATE_CAUSAL_GRAPH 2026-10-03 · codex

    Corrected unrelated citation and claim-level evidence under issue 1301, bounded the graph to an oceanic pathway, replaced unsupported selection sufficiency with particle-associated activity, and retained aerobic scope. Original graph/node/edge IDs and the earlier audit event are preserved.
