Demodulate an acoustic underwater communication using GNURadio. Also, you can use Octave for your initial research.

The signal is modulated in coherent-FSK, using 84.5 kHz for representing the «0» symbol and 85.5 kHz for symbol «1». The transmission speed is 1 kbps.

The following image is a recording of a real transmission.
