Hydrophone Array Raw Data
The raw data format for the Institute for Ocean Sciences (IOS) hydrophone arrays is a binary hyd file. These arrays consistent of three hydrophones, a mounting frame and a data acquisition system. The system collects acoustic data and stores it in 5 minute segments in three separate channels within a single hyd file. MATLAB code was provided by the Instrument Development Group at IOS to read these files. Once read, we produce the standard suite of hydrophone data products (audio data and hydrophone spectral data). For additional information, see the instrument documentation under hydrophones, specifically, devices 22 and 1007, are active on the VENUS network and regularly produce hyd files. As this is a completely custom binary file, only expert users who have access to the aforementioned MATLAB code should download this data (contact us for more information about working with hyd files). The standard hydrophone data products, including wav, MP3 and spectrogram images, are suited for general use.
