ABSTRACT:
An apparatus and method for the in-situ measurement and prediction of the onset of hypoxic conditions in aquatic media is disclosed. The apparatus includes a magnet and sensor for concentrating and measuring biogenic magnetic fields produced by ambient populations of microaerophilic magnetotactic bacteria in aquatic sedimentary environments and means for correlating the measured data with oxygen content in the locations monitored.
