Nutrient release rates from the sediments of Saginaw Bay, Lake Huron

  title={Nutrient release rates from the sediments of Saginaw Bay, Lake Huron},
  author={William J. Ullman and Robert Curwood Aller},
Direct measurements of net production rates and pore water profiles of solutes in the fine-grained sediments of Saginaw Bay, imply corresponding steady-state fluxes to the overlying water of 1.1–1.3 (I), 450–1010 (NH4 +), 1250–2650 (Si(OH)4), 3000–3400 (Ca2+), 440–1330 (Mg2+), 1.5–728 (Fe2+), and 179–281 (Mn2+) μmoles/m2/day and 11.0–11.8 (alkalinity) meq/m2/day at 17.5 °C. Silica production rates in sediments apparently follow first order kinetics with a rate coefficient of ∼0.09/day and a… CONTINUE READING
