Measurement of the bubble population in coastal waters using combination frequencies of MHz order
Leighton, Timothy Grant; Phelps, Andy D.; Ramble, David G. (NATO. SACLANTCEN, 1997)This paper describes the use of a combinatron frequency technique to measure the size distribution of oceanic bubbles. Written between two sea trials, the paper describes how the apparatus cart be adapted to design tests ... -
Sound absorption by suspended particulate matter
Brown, N. R.; Leighton, Timothy Grant; Richards, S. D.; Heathershaw, A. D. (NATO. SACLANTCEN, 1997)A series of experiments has been performed to study the viscous absorption of sound by particulate suspensions typical of those found in coastal waters. The effect due to the particles in the frequency range of 50 - 150 ... -
The effect of suspended particulate matter on the performance of high frequency sonars in turbid coastal waters
Richards, S. D.; Heathershaw A. D.; Brown, N. R.; Leighton, Timothy Grant (NATO. SACLANTCEN, 1997)Shallow coastal environments are characterised by high levels of suspended mineral particles relative lo the open ocean and such suspensions can have a significant effect on the performance of high frequency sonars operating ...
