1995-2005: ten years of active research on underwater acoustic communications in Brest

On the last ten years, GESMA and its main partners, Sercel Brest and ENST Bretagne realized different projects related to underwater acoustic communication. The underwater acoustic channel is so harsh that different strategies have to be considered according to the desired application. From point to point to network and from short to long range, this paper aims to recall these different developments and most significant results.
