Domain-specific¶
- Biological Pump
- The carbonate pump runs in parallel: calcifying organisms — coccolithophores, foraminifera, pteropods — build calcium-carbonate (CaCO₃) shells that sink and dissolve at or below the carbonate compensation depth, releasing DIC at depth; because carbonate production at the surface consumes alkalinity and releases CO₂, the carbonate pump actually has a partial warming effect on atmospheric CO₂, partially offsetting the soft-tissue pump

“An ocean carbon pump is defined as a process that depletes the ocean surface of σCO2 relative to the deep-water σCO2. Three pumps are recognized: a carbonate pump, a soft-tissue pump, and a solubility pump.”

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
