dc.descriptionAs a part of continuing efforts to investigate nitrogen (N) cycling in Texas bays and estuaries, denitrification, N fixation, dissimilatory nitrate reduction to ammonium (DNRA), and sediment oxygen demand (SOD) were measured in East Matagorda Bay, Texas. ... The purposes of this study were to measure nutrient fluxes, denitrification, N fixation, evaluate the relative importance of NO₃⁻ reduction pathways (denitrification and DNRA) in N cycling, and examine environmental conditions influencing N cycling in East Matagorda Bay. A membrane inlet mass spectrometer (MIMS) for dissolved gas measurement and high performance liquid chromatography (HPLC) system for NH₄⁺ isotope measurements were used to quantify denitrification, N fixation, DNRA, and SOD. Six sampling trips to East Matagorda Bay were made in June, July, and October 2001 and January, April, and July 2002. Here, we report water column measurements and incubation experiment results.en_US
