Abstract:

We have processed the archived basebanded complex time series hydrophone data, over the sediment pond, that was acquired with high resolution waveform Upsweep, HFM, 210 - 280 Hz. This data was first unbasebanded to its original band, i.e., from 210 to 280 Hz and then matched filtered with the source replica. For the purpose of geological interpretation, it was then basebanded to a lower frequency which improved the time resolution of the data. The coherent low velocity noise, that was present throughout the data set, was later removed with proper velocity filters. These processing steps helped in revealing the vertical incident coherent events and we give our interpretation of these events. Ocean acoustics, Reverberation.
