This book was released on 1980 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt has been made to trace the contributions of various physical and chemical factors which effect the low frequency attenuation of sound observed in deep ocean channels and to establish that chemical relaxational processes do in fact contribute to the overall attenuation of this sound. The available evidence indicates that below 0.5 kHz, attenuation is affected predominantly by diffraction and diffusive scattering, but in the range 0.5 to 2.5 kHz, it is the effects of chemical relaxation processes, involving boric acid/borate and magnesium/carbonate equilibria, which dominate the sound absorption phenomenon.

This book was released on 1981 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presented the oral and visual presentation entitled 'Low Frequency Sound Absorption in Sea Water: A New Chemical Relaxation Mechanism?, ' presented at the 101st Meeting of the Acoustical Society of America, 18-22 May 1981, in Ottawa, Ontario, Canada. Excess sound absorption in sea water arises mainly from chemical relaxations involving MgS04 and B(OH)3. The high-frequency (100 kHz) MgS04 relaxation has been identified as a multistep ion-pair process. The low frequency (1 kHz) and B(OH)3 relaxation apparently involves more complex interactions with other constituents. To investigate B(OH)3 interactions in a simpler system, we measured absorption in NH3 solution using the resonator method. We have found alpha max to be proportional to the product of NH(+) and B(OH)4( - ) concentrations; however, the magnitude is much too large to be caused by the ion pair. The mechanism, probably similar to that in sea water, resembles catalysis, the absorption being governed by the large volume change of the faster NH3/NH4(+) equilibrium and the relaxation frequency by the slower B(OH)3/B(OH)4( - ) equilibrium.

Available in PDF, EPUB and Kindle. Book excerpt: Temperature-jump measurements in sea water over the time domain 0.00001 to 0.01 sec reveal a single relaxation of 0.00015 sec at 9.7C, which appears to correspond to the approximately 1 kHz relaxation found from long range sound propagation. Laboratory measurements indicate the relaxation to originate from boron with the B(OH)3 - B(OH)4 - equilibrium the likely relaxing process. (Author).

This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The absorption of sound in sea water at low frequency (1-100 kHz) and intermediate frequency (50-500 kHz) ranges can be defined by a series of relaxation phenomena, each of which can be described mathematically by a Debye relationship. Below 5 kHz, the principal absorption mechanism is attributed to borate and magnesium/carbonate interactions, while in the range 5 to 50 kHz the absorption arises from magnesium sulphate ion pair formation in sea water. The dependence of the various relaxation modes on oceanographic variables is outlined in quantitative terms based on results from deep ocean sound channel experiments and laboratory experiments.
