Abstract: The performance of collaborating information systems in the hydrosphere is based on the robustness and tolerance of the wireless communication task. It is strongly intertwined with the cooperation and coordination reliability under water for sharing resources and common purposes. Key technology and bottleneck is the physical layer communication in the underwater ’chameleon’ acoustic channel environment and the challenges of non trivial channel effects like the multipath propagation - which is rapidly varying over time and space. In this contribution we introduce the burst communication as one possible solution. These transmissions are supposed to be of a very short duration. The purpose is to occupy the acoustical channel in the underwater column only for a short time window, like in impulse and click communication (similar to the use by marine mammal, Khoisan and wugbe languages), e.g. to reduce the probability of transmission collisions and allows an efficient EMission CONtrol (EMCON).
