Environmental Context. The interpretation of CLE-AdSV based iron(iii) speciation data for marine waters has been called into question in light of the kinetic features of the measurement. The implications of the re-think may have consequences for understanding iron biogeochemistry and its impact on ecosystem functioning. The challenging of previously accepted results stimulated this debate on what is actually being measured by the CLE-AdSV technique.

Keywords. biogeochemistry — electrochemistry (analysis) — iron — speciation (metals)
