The efficacy of sound to penetrate the seas made acoustic systems in the past century the leading tools for sensing objects in and measuring properties of the seas. For over sixty years The United States Office of Naval Research (ONR) has been a major sponsor of undersea research and development at universities, national laboratories, and industrial organizations. App- priately ONR is the sponsor of this monograph series. The intent of the series is to summarize recent accomplishments in, and to outline perspectives for, underwater acoustics in specific fields of research. The general field...

This dynamic, event-centered anthology offers a new understanding of the hundred-year history of German-language film, from the earliest days of the Kintopp to contemporary productions like The Lives of Others. Each of the more than eighty essays takes a key date as its starting point and explores its significance for German film history, pursuing its relationship with its social, political, and aesthetic moment. While the essays offer ample temporal and topical spread, this book emphasizes the juxtaposition of famous and unknown stories, granting attention to a wide range of cinematic...

Shear waves and closely related interface waves (Rayleigh, Stoneley and Scholte) play an important role in many areas of engineering, geophysics and underwater acoustics. In some cases interest is focused on large-amplitude waves of low frequency such as those associ ated with earthquakes and nuclear explosions; in other cases low amplitude waves, which have often travelled great distances through the sediment, are of interest. Both low and high frequency shear and interface waves are often used for seafloor probing and sediment characterization. As a result of the wide spectrum of different...
