Development of an instrumentation platform for ocean noise data acquisition and analysis

摘要

An instrumentation platform, comprising of an acquisition hardware, signal conditioning module, hydrophones and a host PC, has been developed for the ocean noise data acquisition and analysis. The software used for the platform provides interfaces to acquisition hardware and recorded sound files. It also features a GUI frame work for the display, monitoring and analysis of the data. Several recordings of the ocean noise data waveforms have been made using this instrumentation platform during the recent acoustic surveys in FORV Sagar Sampada and the recorded sound files have been analysed for generating the spectrogram, power spectrum and time series representations.
