Investigations of the isotope ratios of dissolved oxygen (δ O ) provide valuable information about the oxygen cycle in aquatic systems. However, oxidation of Fe(II) may change pristine δ O values during storage and can lead to a misinterpretation. We sampled an Fe(II)-rich spring system and measured δ O values at various time intervals in order to determine influences of Fe-oxidation. Water samples were collected from an Fe-rich spring and related stream and the δ O values were measured in fresh, 4- and 13-day-old samples with an is
