Abstract
Related literature has shown that internal waves (IWs) observed in the ocean are capable of producing secondary magnetic fields with a small signal-to-noise ratio due to the flow of dissolved salts. It can be difficult to characterize these signals since they are relatively weak, highly transient, and capable of being multi-modal. Using data collected by an array of magnetometers and acoustic Doppler current profilers, a technique called magnetic anomaly and particle velocity array correlator was developed for the detection of IWs. By using a combination of filtering techniques and a multi-variate correlation step, peak correlations above 90% were shown between the magnetic and water particle velocity records of potential IWs.
