Extended Data Table 1.

Most probable model parameter values with their uncertainties (±1σ)

The definitions of the parameters are presented in Methods. M1 and M2 are models parameterized according to SeaWiFS CbPM and CAFE, respectively. The shaded column represents the results reported in the main text.

^*κ_dX = κ_XθQ₁₀^(T−30)/10, semi-labile DOP or DOC remineralization e-folding time.

^†b(X) = b_XθT + b_X, Martin curve exponent, in which T is the average surface ocean temperature (upper approximately 100 m), X represents C or P.

^‡Reciprocals of e-folding remineralization time of refractory DOC in the upper (κ_ru) and deep (κ_rd) oceans.

^§Length scale of PIC dissolution.

^||R_RR = r_Si[SiO₄⁴⁻] + r_RR, function of PIC to POC production ratio.

^¶Ratio of P:C: r_P:C = cc[DIP] + dd.
