  • Effects of redox potential and pH changes on phosphorus retention by melter slag filters treating wastewater

    Authors
    Andy Shilton, R.G. Haverkamp, S. Pratt, C. Pratt, I. Elmetri
    Journal
    Environmental Science and Technology
    Year
    2007
    The release of phosphorus (P) and iron (Fe) from a melter slag filter in solutions of varying Eh and pH was examined. The filter had been removing P from waste stabilization pond effluent for several ... REGISTER NOW TO SEE MORE

  • Physical mixing effects on iron biogeochemical cycling: FeCycle experiment

    Authors
    Keith Hunter, Peter D. W. Boyd, C.S. Law, E.R. Abraham, P.L. Croot, S. Sander, M.J. Ellwood, S.E. Pickmere, M.J. Smith
    Journal
    Journal of Geophysical Research C: Oceans

    2007
    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

  • 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
    Journal

    2005
    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

  • Macronutrient and trace-metal geochemistry of an in situ iron-induced Southern Ocean bloom

    Authors
    S. Pickmere, P. Croot, A. Bowie
    Journal
    Deep-Sea Research Part II: Topical Studies in Oceanography
    Year
    2001
    We have investigated the effect of iron supply and increased phytoplankton growth on the cycling of the macronutrients phosphate, nitrate and silicic acid as well as the micronutrients copper (Cu), ni... REGISTER NOW TO SEE MORE
