Estimation of sediment denitrification rates at in situ nitrate concentrations.
The denitrification rates in a marine sediment, estimated by using N-nitrate, V(max), K(m), and sediment nitrate concentrations, were 12.5 and 2.0 nmol of N(2)-N cm day at 0 to 1 and 1 to 3 cm, respectively, at 12 degrees C. The total rate was 165 nmol of N(2)-N m day.
متن کاملEstimating Rates of Denudation Using Cosmogenic Isotope Abundances in Sediment
We propose, as a testable hypothesis, a basin-scale approach for interpreting the abundance of in situ produced cosmogenic isotopes, an approach which considers explicitly both the isotope and sediment flux through a drainage basin. Unlike most existing models, which are appropriate for evaluating in situ produced cosmogenic isotope abundance at discrete points on Earth’s surface, our model is ...
متن کاملDenitrification measurements of sediments using cores and chambers
Denitrification is commonly measured using in situ benthic chambers or laboratory incubations of sediment cores. These techniques are similar in principle but differ considerably in cost and practicality. Despite widespread use of both techniques, it is uncertain whether they give comparable results. We compared cores and chambers for measuring fluxes (dissolved oxygen [DO], N2, NH4, NO3 and NO...
متن کاملNitrification, Denitrification and Nitrate Reduction Rates in the Sediment of Hiroshima Bay, Japan
Nitrification, denitrification and nitrate reduction rates in the sediments at two stations in Hiroshima Bay were studied seasonally from August 1994 to May 1995. The acetylene (C2H2) inhibition technique was used to evaluate the rate of these processes. The seasonal average of nitrification and denitrification rates ranged from 0.00 to 299 μg atN m–2h–1 and 0.00 to 69.0 μg atN m–2h–1, respecti...
