Abstract

Magnetotactic bacteria apparently only secrete magnetite under conditions of low oxygen and have high turnover rates in nitrate and ammonia-rich environments. These geochemical conditions commonly exist where productive aerobic waters are in contact with anaerobic waters. This has relevance for environmental monitoring and prediction of the onset of hypoxia in bottom waters. If the magnetic signal is preserved over time, the technique also may prove useful in geochemical prospecting and in paleooceanographic and paleoecological studies
