[edit] Summary

This diagram shows the origins of the terms new and regenerated production. New production is that derived from nitrate (NO₃^-), while regenerated production is derived from ammonium (NH₄⁺). Since nitrate is believed to only be produced at depth (via nitrification), knowing the ratio between new and regenerated production (the so-called f-ratio) allows one to infer the flux of organic nitrogen from the photic zone to the aphotic zone.
