Anammox and denitrification in the oxygen minimum zone of the eastern South Pacific
Anammox and denitrification oxygen minimum zone eastern South Pacific
2014/4/4
We quantified the removal of fixed nitrogen as N2 production by anammox and N2 and N2O production by denitrification over a distance of 1900 km along the coasts of Chile and Peru, using short-term inc...
Quantifying denitrification in rippled permeable sands through combined flume experiments and modeling
Quantifying denitrification rippled permeable sands combined flume experiments modeling
2014/4/4
We measured denitrification in permeable sediments in a sealed flume tank with environmentally representative fluid flow and solute transport behavior using novel measurements. Numerical flow and reac...

We quantified the removal of fixed nitrogen as N2production by anammox and N2and N2O production by denitrification over a distance of 1900 km along the coasts of Chile and Peru, using short-term incub...
Differences in benthic metabolism, nutrient fluxes, and denitrification in Caulerpa taxifolia communities compared to uninvaded bare sediment and seagrass (Zostera capricorni) habitats
Differences in benthic metabolism nutrient fluxes denitrification in Caulerpa taxifolia communities uninvaded bare sediment and seagrass Zostera capricorni habitats
2014/4/4
Benthic metabolism, nutrient fluxes, and denitrification were measured in Caulerpa taxifolia communities that had recently invaded (between 2003 and 2008) bare sediments following the loss of Zostera ...
Denitrification and nitrous oxide cycling within the upper oxycline of the eastern tropical South Pacific oxygen minimum zone
Denitrification nitrous oxide cycling
2014/4/17
One of the shallowest, most intense oxygen minimum zones (OMZs) is found in the eastern tropical South
Pacific, off northern Chile and southern Peru. It has a strong oxygen gradient (upper oxycline) ...
Rates and regulation of anaerobic ammonium oxidation and denitrification in the Black Sea
Rates and regulation anaerobic ammonium oxidation denitrification Black Sea
2014/4/18
We performed incubation experiments with 15N-labeled nitrogen compounds to investigate the vertical distribution of pathways of N2 production through the suboxic zone of the central Black Sea and the ...
Shift from denitrification to anammox after inflow events in the central Baltic Sea
denitrification anammox after inflow events central Baltic Sea
2014/4/22
Incubation experiments with 15N-labeled compounds (NO3- and NH4+) were performed during three cruises (2002, 2004, and 2005) to study the loss of inorganic N as dinitrogen gas (N2) via denitrification...
