Short summary
Ocean carbon flux, seafloor respiration, and seafloor carbon burial are calculated from plankton respiration. Based on this respiration, a new parameter, the heterotrophic energy production - the rate of ATP generated in seawater, is calculated, and a new concept, the nutrient retention efficiency (NRE), and its ocean variability, is developed and demonstrated. Finally, the curvature of the respiration profile is discovered to be the control - key for NRE and carbon flux.
