Insights into the bioavailability of oceanic dissolved Fe from phytoplankton uptake kinetics
We evaluated dFe bioavailability in 12 water samples from different locations and depths (Table 1; Supplementary Table S1) by conducting ~85 short-term Fe uptake experiments with Fe-limited cultures of 7 different phytoplankton strains varying in size, taxa, and isolation site (Table 2). From these measured Fe uptake rates, we calculated the dFe uptake rate constant for each experiment, […] More
