The Detection of Medium Scale Conductivity Anomalies in the Ocean

Many phenomena of interest and concern to humanity generate large volumes of water of anomalous conductivity in the ocean. The Conductivity Anomaly Detector (CAD) is a device that can be used to locate and map these areas of anomalous conductivity in a facile and rapid manner. In operation the CAD generates an AC field on the order of hundreds of meters in length. As the detector is towed through a volume of water containing large amounts of water of anomalous conductivity, the applied field is deformed. The amount of deformation of the field is related to the nature and location of the anomalous water mass. The device measures the degree of deformation of the applied field and can therefore detect and map the area containing the anomalous water.
