Domain-specific¶
- Biological Pump
- Martin proposed that in "high-nutrient, low-chlorophyll" regions like the Southern Ocean, phytoplankton growth is limited not by nitrate or phosphate but by scarce iron, and that adding iron would stimulate a bloom that pumps carbon downward
This sourceMartin's iron hypothesis that Southern Ocean new production is iron-limited despite excess surface nitrate and phosphate, and that Fe enrichment could enhance growth and draw down atmospheric CO2.

“is limited by iron deficiency, and hence the phytoplankton are unable to take advantage of the excess surface nitrate/phosphate”

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. 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.
