- Abstract
During November 2017, an active source seismic survey was performed in Andaman Sea to study the acoustic propagation characteristics. High power low frequency acoustic signals generated by 20-air gun array onboard Research Vessel Samudra Ratnakar were recorded from INS Sagardhwani at four different depths within 8 km ranges in shallow and deep waters. The received level was estimated using root mean square and power spectral values. Amplitude levels were analysed with respect to arrival time variation with frequency and is presented.
