Cycling of reduced trace gases and hydroxylamine in coastal waters
The distributions and fluxes of methane, carbon monoxide, nitrous oxide, hydrogen, and hydroxylamine were examined in Yaquina Bay, a relatively unpolluted estuary on the coast of Oregon, and Big Lagoon, a meromictic, coastal lagoon in Northern California. Special emphasis was placed on measuring hydroxylamine, a potential precursor to nitrous oxide in aquatic systems. A gas chromatographic method that is independent of pH and salinity was developed, thus allowing measurement of nanomolar concentrations of hydroxylamine in euryhaline waters for the first time. The kinetics of this reaction involving oxidation of hydroxylamine by iron(III), were examined in detail and suggest a complex reaction sequence with a number of possible end products.
