    The effects of physical processes on the distribution, speciation, and sources/sinks for Fe in a high-nutrient low-chlorophyll (HNLC) region were assessed during FeCycle, a mesoscale SF6 tracer releas... REGISTER NOW TO SEE MORE

  • Particulate iron dynamics during FeCycle in subantarctic waters southeast of New Zealand

    The FeCycle experiment provided an SF6 labeled mesoscale patch of high-nitrate low-chlorophyll (HNLC) water in austral summer 2003. These labeled waters enabled a comparison of the inventory of partic... REGISTER NOW TO SEE MORE

  • FeCycle: Attempting an iron biogeochemical budget from a mesoscale SF6 tracer experiment in unperturbed low iron waters

    Authors
    Keith Hunter, Peter D. W. Boyd, C.S. Law, D.A. Hutchins, E.R. Abraham, P.L. Croot, M. Ellwood, M. Hadfield, J. Hall, S. Handy, C. Hare, J. Higgins, P. Hill, K. LeBlanc, M.T. Maldonado, R.M. McKay, C. Mioni, M. Oliver, S. Pickmere, M. Pinkerton, K. Safi

    An improved knowledge of iron biogeochemistry is needed to better understand key controls on the functioning of high-nitrate low-chlorophyll (HNLC) oceanic regions. Iron budgets for HNLC waters have b... REGISTER NOW TO SEE MORE

  • Role of iron, light, and silicate in controlling algal biomass in subantarctic waters SE of New Zealand

    Authors

    Journal
    Journal of Geophysical Research C: Oceans
    Year
    1999
    Phytoplankton processes in subantarctic (SA) waters southeast of New Zealand were studied during austral autumn and spring 1997. Chlorophyll ? (0.2-0.3 ?g L-1) and primary production (350-650 mg C m-2... REGISTER NOW TO SEE MORE
