||P.519 right column bottom paragraph: "The baseline for studies of the elemental stoichiometry of marine microorganisms was established more
than 60 years ago by Alfred Redfield, who estimated that marine plankton (and organic marine detritus) have a carbon/nitrogen/phosphorus (C/N/P) ratio of 106/16/1 (primary source 14). The Redfield ratio remains the foundation for studies of the elemental composition of marine microorganisms and organic matter, particularly in the deep oceans [refs 4,15]."
