Abstract: In the past few years Rapid Environmental Assessment (REA), applied to shallow waters, has become one of the most challenging topics in ocean acoustics. The REA concept evolved after the cold war when the outset of regional conflicts shifted the potential operational areas from open ocean towards littoral areas, and has been identified by NATO as a new warfare requirement. REA must provide detailed and accurate information, in near real time, in order to prepare the maritime forces deployment into highly variable coastal waters that are not well known. More recently REA has become a promising technique for civil and scientific environment monitoring. Such an interest arises because the coastal transition zone is a region of significant fishing effort and of intense ship traffic. The rapid knowledge of the dynamics and structure of coastal zones would assume strong importance in the case of natural or man made hazards. Because of the short time required for REA applications, the main topics of REA have been identified as rapid data collection, data synthesis and assessment, and dissemination of assessed products to action groups.
