This book was released on 1974 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report begins by presenting a general solution for the electromagnetic field induced by an irrotational flow field using Ampere's law and Faraday's law and show that fields are determined by an electromagnetic potential function and a velocity potential function. Then it determines solutions corresponding to progressive waves in a horizontally stratified ocean. It investigates fields produced by progressive waves in a deep ocean and then considers fields produced by progressive waves in shallow seas. In each case, it presents fields produced by both surface and internal waves in both polar and equatorial regions. Finally, it gives complete expressions for electromagnetic potential functions corresponding to surface and internal waves.

Book excerpt: This paper provides a comprehensive account of analytical results for computing electromagnetic fields that are induced by ocean sea water as a result of its motion relative to the geomagnetic field. The emphasis is on the characterization of magnetic field and magnetic field gradient spectra induced by internal waves and surface waves in a deep ocean environment. The theoretical results are formulated so as to be directly applicable to the computation of sea water generated magnetic noise and to the assessment of its deleterious effects on the sensitivity of magnetic sensors employed for magnetic anomaly detection over an open ocean. Magnetic field component and gradient spectra are computed both for stationary and moving sensor observation platforms.

Book excerpt: In its relentless pursuit of further knowledge, science tends to compartmentalize. Over the years the pursuit of What might be called geophysical acoustics of the sea-surface has languished. This has occured even through there are well-developed and active research programs in underwater acoustics, ocean hydrodynamics, cloud and precipitation physics, and ice mechanics - to name a few - as well as a history of engineering expertise built on these scientific fields. It remained to create a convergence, a dialogue across disciplines, of mutual benefit. The central theme of the Lerici workshop, perhaps overly simplified, was 'What are the mechanisms causing ambient noise at the upper surface of the ocean?' What could hydrodynamicists contribute to a better understanding of breaking wave dynamics, bubble production, ocean wave dynamics, or near-surface turbulence for the benefit of the underwater acoustics community? What further insights could fluid dynamicists gain by including acoustic measurements in their repertoire of instrumentation? While every attendee will have his or her percep tions of details, it was universally agreed that a valuable step had been taken to bring together two mature disciplines and that significant co-operative studies would undoubtedly follow. The scope of the workshop was enlarged beyond its original intent to also include the question of ice-noise generation. The success of this decision can be seen in high quality of the presentations. the contribution of its disciples in the other workshop discussions and the heightened awareness and interest of we other novices.

Download or read book The Electrical Field Induced by Ocean Currents and Waves with Applications to the Method of Towed Electrodes written by and published by . This book was released on 1911 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this paper is to discuss the nature of the electrical field induced in the ocean by particular types of velocity distribution. It is believed that these examples will be helpful in the interpretation of measurements by towed electrodes in the sea. The electrical field induced by waves and tidal streams, originally predicted by Faraday (1832), was first measured experimentally by Young, Gerrard and Jevons (1920), who used both moored and towed electrodes in their observations. Recently, the technique of towed electrodes has been developed by von Arx (1950, 1951) and others into a useful means of detecting water movements in the deep ocean. While the method has been increasingly used, the problem of interpreting the measurements in terms of water movements has become of great importance. Two of the present authors have made theoretical studies (Longuet-Higgins 1949, Stommel 1948) dealing with certain cases of velocity fields, and Malkus and Stern (1952) have proved some important integral theorems. There seems, however, to be a need for a more extended discussion of the principles underlying the method, and for the computation of additional illustrative examples. This is all the more desirable since some of the theoretical discussions published previously have been misleading.
