----------------------

The 600 000 Hz Sampling Rate Stereo recordings have been realised by the new card JASONv3 designed and build by the 
university of TOULON, FRANCE,
at the 'Smart Microsystems and Internet of Things' department (SMIoT  http://smiot.univ-tln.fr).

JASONv3 allows up to 5 channels x 1mHz SR 16 bits recordings.
The hydrophones are the C55 and C57 from Cetacean Research, USA.

They are powered at 9V by JASONv3, itself powered at 12V (8x1.5V D alcaline batteries).
The gain of JASON = 1.
The inter-hydrophone distance is 65 to 69 cm (depends on the exact position of the piezo into the hydrophone).
The hydrophones are offaxis to each other.

They are simultaneously connected to a Zoom H1.
The 96 000 Hz SR 24 bits are done on this Zoom H1 with its adaptive gain in inline input. 
The zoom is powered by 2 x 1.5 V AA batteries.

A Gopro3 is placed in middle of the two hydrophones (3 degrees left).

The whole instrument is named Blue4D.

* Files Content : 
-----------------
The given session has been recorded by F. Sarano in Mauritus march 2017.

The GOPROs (Medium F) are taken from the Blue4D hydrophone antenna, and synch. with some audio recordings. The GOPRO*.wav are extracted from the GoPro.
The JASON_UTLN_yyyymmdd_hhmmssUTC are the JASON recordings
(to remove flow noise and little interferences, *cut* extracted files are high pass filtered by butterworth 8kHz 48dB/oct, except the *Coda* at 4kHz 12dB/oct).

The ZOOM000x.WAV are the zoomH1 recordings.
The File_table.ods gives offset between the Gopro, JASON and Zoom files.
