Dissolved iron and Fe(II) in an iron induced Southern Ocean phytoplankton bloom measured during TANGAROA cruise SOIREE, supplement to: Croot, Peter L; Bowie, Andrew R; Frew, Russell; Maldonado, Maria T; Hall, Julie A; Safi, Karl A; La Roche, Julie; Boyd, Philip W; Law, Cliff S (2001): Retention of dissolved iron and Fe II in an iron induced Southern Ocean phytoplankton bloom. Geophysical Research Letters, 28(18), 3425-3428
During the 13 day Southern Ocean Iron RE-lease Experiment (SOIREE), dissolved iron concentrations decreased rapidly following each of three iron-enrichments, but remained high (>1 nM, up to 80% as FeII) after the fourth and final enrichment on day 8. The former trend was mainly due to dilution (s...
