Download or read book Variableness of the Sound Velocity Profile about the Mid Atlantic Ridge Axis written by Eli Joel Katz and published by . This book was released on 1969 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean Water, spreading across the North Atlantic Ocean, is shown to cause a disturbance to the acoustic medium in the vicinity of the Mid-Atlantic Ridge north of the Azores. In this region, the ridge crests are sufficiently shallow so as to impede the free movement of the intermediate waters. Warm and saline layers, nearly two hundred meters thick, were repeatedly observed in the lowering of continuous sampling sensors. These inversion layers are shown, by reconstruction, to result from local water movement across the ridge crest and are argued to be short lived and spatially confined. As a direct consequence the observed depth of the sound velocity minimum unpredictably fluctuated as much as five hundred meters within an area of two hundred miles square. The layers themselves result in secondary sound channels. The inversions of both temperature and salinity combine to produce inversions in the sound velocity profile of four meters per second, deep in the thermocline. (Author).

This book was released on 1969 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustic data from the files of the Woods Hole Oceanographic Institution are presented in a form which permits direct comparison with a surface-layer, sound transmission, prediction program operated by the Fleet Numerical Weather Central, Monterey. A total of nine exercises, typically providing data at several ranges and several shots at each range, are compared. Transmission ranges vary from a minimum of one to a maximum of nineteen kiloyards. Frequencies span the range 0.1 - 10 kHz. (Author).

Download or read book The Upper and Deep Sound Channel in the Northeast Atlantic written by Don F. Fenner and published by . This book was released on 1969 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of extensive historical sound velocity profile data east of the Mid-Atlantic Ridge between 20 degrees N latitude and Iceland indicates that warm, saline Mediterranean Intermediate Water and the effects of annual heating and cooling are responsible for marked departures from the basic trilinear vertical sound velocity structure found in most open ocean areas. South of about 43 degrees N latitude, Mediterranean Intermediate Water between 1000 and 1300 meters causes the formation of a subsurface sound velocity maximum, thereby creating an upper sound channel and a depressed deep sound channel. North of about 50 degrees N latitude, winter cooling causes the formation of a subsurface sound velocity maximum and summer warming results in the formation of a somewhat shoaler upper sound channel. Temperature-salinity and sound velocity comparisons for 12 selected locations throughout the Northeast Atlantic Ocean are presented in the appendix. (Author).
