The vertical distribution of dissolved hydroxylamine (NH<sub>2</sub>OH) was
measured for the first time at 10 stations in the western, southern and
central Baltic Sea during a cruise in February 2004. The distribution of
dissolved NH<sub>2</sub>OH was complex due to the interplay of in-situ production
in the shallow western and southern Baltic Sea and the hydrographical
setting in the central Baltic Sea caused by the major North Sea water inflow
event in January 2003. We conclude that nitrification might be the major
source of NH<sub>2</sub>OH, whereas anaerobic ammonium oxidation (anammox)
appeared to be negligible. We suggest that a "fresh" nitrifying system, in
which the NH<sup>+</sup><sub>4</sub>-oxidation rates exceeded the
NO<sup>−</sup><sub>2</sub>-oxidation rates, favoured the build-up of NH<sub>2</sub>OH.
