This is the sound of an iceberg I have recorded in Antarctica in 2009. The iceberg was a big one, more than 40m high! Despite the icebergs are trapped in the ice shelf, they move due to the tide and the low frequency waves coming from the open sea which propagate under the ice shelf. Those movements produce very powerful and impressive grinding noise!
The iceberg was 8km away from the scientific base of Dumont D'Urville in Terre Adélie and far away from the open sea (at least 100km).

It was a bit challenging to do such record. It was cold (not a surprise) and very windy most of the time! This was also a place you don't want to stay too long as pieces of ice fell around.

Microphone: Rode NT4, homemade preamp, M-Audio microtrack II.

A picture of the iceberg is visible on my flickr page here:

Let me know what this sound does on you!

    No secret here. My home-made preamp is based on the SSM2019 and OPA2134 amplifier ICs. I have kept the circuit diagram as simple as possible. There is no phantom power (no need as the NT4 has its own battery). Coupling cap are Elna RFS (SILMIC II) in parallel with large 1µ polypropylene cap.
    Smaller value filtering caps are styrene caps or polypropylene cap. The potentiometer is a stereo large cermet alps potentiometer. If you are interested in DIY electronic, I might drop the diagram on my blog. Just let me know.

    I'm now working on a high end digital amplifier with spdif output, unfortunately I lack of free time to finish the board (I just have to finish the design of the +48V phantom power to complete the job)
