Winter-time dissolved iron and nutrient distribution in the Subantarctic Zone from 40-52S; 155-160E
In HNLC oceanic regions, iron (Fe) controls phytoplankton productivity yet large gaps remain in our understanding of iron's biogeochemical cycle. Here we present the first comprehensive winter dataset for dissolved Fe (dFe) and nitrate (NO3) distributions (0-1000 in depth) between 40S-52S, which transects the Subantarctic zone (SAZ), west of New Zealand. Surface concentrations (<0.2 nmol Fe kg-1) were conspicuously low, i.e., probably biologically limiting even at winter-reserve levels, at...[Show more]
