Extended Data Fig. 8: Distributions of exponent b values for the non-advective-diffusive carbon flux.
From: Biological carbon pump estimate based on multidecadal hydrographic data
a,b, The optimal b-value distributions based on SeaWiFS CbPM and CAFE products, respectively. c,d, The projected change in the b-value according to temperature prediction by a CESM-BGC model prediction under the RCP8.5 scenario in the year 2099 (ref. 51). Larger b-values implies that respiration occurs nearer the sea surface.
