A magnetic anomaly and particle velocity array correlator for the detection of internal waves in the ocean

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, a...

Summary: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.
