A vivid portrait of how Naval oversight shaped American oceanography, revealing what difference it makes who pays for science. What difference does it make who pays for science? Some might say none. If scientists seek to discover fundamental truths about the world, and they do so in an objective manner using well-established methods, then how could it matter who’s footing the bill? History, however, suggests otherwise. In science, as elsewhere, money is power. Tracing the recent history of oceanography, Naomi Oreskes discloses dramatic changes in American ocean science since the Cold War, uncovering how and why it changed. Much of it has to do with who pays. After World War II, the US military turned to a new, uncharted theater of warfare: the deep sea. The earth sciences—particularly physical oceanography and marine geophysics—became essential to the US Navy, which poured unprecedented money and logistical support into their study. Science on a Mission brings to light how this influx of military funding was both enabling and constricting: it resulted in the creation of important domains of knowledge but also significant, lasting, and consequential domains of ignorance. As Oreskes delves into the role of patronage in the history of science, what emerges is a vivid portrait of how naval oversight transformed what we know about the sea. It is a detailed, sweeping history that illuminates the ways funding shapes the subject, scope, and tenor of scientific work, and it raises profound questions about the purpose and character of American science. What difference does it make who pays? The short answer is: a lot.

"This is the first history of the Royal Navy's part in research in underwater acoustics. Between 1914 and 1954 the submarine evolved into an underwater warship whose most dangerous weapon was its ability to hide in a mass of water. Of the many techniques that were tried to deprive it of that advantage, those based on sonar have been the most effective. At the beginning of the First World War, the British Navy had almost no means of tackling the danger of German U-boats. The use of hydrophones - underwater microphones - proved of limited value, and in 1917 work began on the development of an "active" detection device. This was based on French research into the capacity of certain crystals to act as transmitters and receivers of high-frequency sound waves. These move about four times faster through water than through air, but their exact speed varies with temperature, pressure and salinity - and, as scientists discovered, these differ considerably in different parts of the oceans. Another complication is that as sound travels away from whatever has produced it, its energy diminishes. As a result of this, and of the distortion caused by reflection from both surface and sea bed, the echo from a target has only a fraction of the energy of the transmitted sound impulse. In the mid 1920s experiments were begun with magnetostrictive transducers, first used in the British Navy's attack sonar sets after the Second World War. They in turn have, for certain purposes, been replaced by electrostrictive ceramic transducers. In 1919 the average echo range was about 457m (500 yds); in the Second World War it was about 1.2km (1300 yds); at the end of this history it had increased to several miles. This book, through careful research, has brought together in a clear and absorbing way the different aspects of British naval development: the impact of tactical and strategic needs on that development; the evolution of sonar; and the transformation of small-scale technical research into a complex organisation involving government and industry." -- back of book.
