All,

as you  might have heard in the past, Alfred Wegener Institute in Bremen (awi) has been using Barix products (namely, Barionet and Instreamer) in a science mission (PALAOA) in antarctica since quite some years now. The Barionets are used for general control and power management, while the Instreamer is used to realtime encode audio from Hydrophones and stream to Neumeyerstation located in Antarctica as well.

There is a very nice, detailed paper available from the PALAOA website (link: here), explaining details and difficulties of the whole setup.

Here is another link to the story, this time in german, with more the scientific view, sound samples etc: PALAOA.

And here is a direct link to the live stream from Antarctica, encoded by a Barix Instreamer: http://icecast.awi.de:8000/PALAOA.MP3

One thing to notice .. Barionet and Instreamer, both standard “consumer temp range” Barix products, work flawlessly since years in the setup in Antarctica, being operated sometimes at -50’C, constantly (24/7) delivering control and monitoring of the station and an IP Audio feed of the hydrophone(s).

What works that reliably in this remote location under extreme conditions should do well for you too, ain’t it ?
