Fig. 1: Diagenetic model of seawater Ca influence on CFA and P burial.
From: The role of calcium in regulating marine phosphorus burial and atmospheric oxygenation
PCFA represents burial concentration of CFA-associated phosphorus in marine sediments. a–b The effects of seawater dissolved calcium concentration ([Ca]SW) upon PCFA and P burial efficiency. Labeled fluxes indicate rates of organic matter loading at the sediment–seawater interface.
