Available in PDF, EPUB and Kindle. Book excerpt: Observations between 20 and 40 m depth were made with a towed thermister chain in the North Pacific. Despite the rapid vertical variation of buoyancy frequency, spectra of isotherm displacements are in fair agreement with other observations and with the Garrett-Munk model. The spectra show evidence of a shoulder and break in slope at a wavelength of 1 km. There is no evidence of significant variation of spectral levels as a function of buoyancy frequency, tow direction or wind speed. A peak at a wavelength of 1 km in coherence spectra between pairs of isotherms separated in the vertical suggests that internal wave energy at this wavelength is dominated by the low modes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Profiles of temperature versus depth in the top 440 m of the sea were taken repeatedly at three horizontal locations surrounding the Research Platform FLIP. The time fluctuation of the temperature profiles was used to determine isotherm displacement and slope variation in the region 60-400 m. Measurements were taken during three FLIP operations. Two were off the California coast, in November 1972 and June 1973. Horizontal and vertical coherence measurements indicate that the internal wavefield can be divided into two frequency regions. Above 2 cph the bandwidth of energetic horizontal and vertical wavenumbers is comparatively narrow. The isotherm displacement spectrum and slope spectrum have irregular slopes. A comparison of the two spectra indicate that first mode is strongly dominant. Below 2 cph, the bandwidth of energetic wavenumbers is broader, corresponding to many energetic modes.

Available in PDF, EPUB and Kindle. Book excerpt: Observations of high frequency internal waves were made from 1 to 14 December 1966, in the deep sea off Baja, California. The fluctuations of the depth of an isotherm were measured with a three-element horizontal array attached to a stable platform. The waves are characterized as a broad band phenomenon with a continuous distribution in frequency. For short intervals of time, a narrow frequency band within the continuum is adequately described as a horizontally plane wave of a single vertical mode. Furthermore, this simplified structure is stationary over time spans of several days. High modes are present in the low frequency waves. Above 4 cycles per hour, however, the first mode predominates. The spectral shape is consistent with the shear limited equilibrium spectrum proposed by Phillips (1966). In addition, the predominance of the first mode at high frequencies further emphasizes the importance of shear instability in internal wave propagation. The horizontal properties of the wave field indicate well-defined directions of narrow-band propagation. These directions and the dispersive properties of the propagation have led to the identification of local topographic features in generating areas of internal waves. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a detailed study of the structure and variability of internal tides and their geographical distribution in the ocean. Based on experimental analysis of oceanic measurements combined with numerical modeling, it offers a comprehensive overview of the internal wave processes around the globe. In particular, it is based on moored buoys observations in many regions in all oceans (Atlantic, Pacific, Indian, Arctic, and Southern) that have been carried out by researchers from different countries for more than 40 years as part of various oceanographic programs, including WOCE and CLIVAR. However, a significant portion of the data was collected by the author, who is a field oceanographer. The data was processed and interpreted on the basis of the latest knowledge of internal wave motion. The properties of internal waves were analyzed in relation to the bottom topography and mean state of the ocean in specific regions. Internal waves play a major role in the formation of seawater stratification and are responsible for the main processes of ocean dynamics, such as energy transfer and mixing. One of the most significant ideas presented in this book is the generation of internal tides over submarine ridges. Energy fluxes from submarine ridges related to tidal internal waves greatly exceed the fluxes from continental slopes. Submarine ridges form an obstacle to the propagation of tidal currents, which can cause the creation of large amplitude internal tides. Energy fluxes from submarine ridges account for approximately one fourth of the total energy dissipation of the barotropic tides. Model simulations and moored measurements have been combined to generate a map of global distribution of internal tide amplitudes. This book is of interest to oceanographers, marine biologists, civil engineers, and scientists working in climate research, fluid mechanics, acoustics, and underwater navigation.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains a comprehensive study of the internal ocean waves, which play a very important role in ocean physics providing mechanisms for ocean water mixing and circulation, as well as the transportation of gases, nutrients, and a very large number of marine organisms in the ocean body. In contrast to surface waves, the literature on internal waves is not so numerous, mainly due to the difficulties in experimental data collection and in the mathematical description of internal wave propagation. In this book, the basic mathematical principles, a physical description of the observed phenomena, and practical theoretical methods of determination of wave parameters as well as the original method of observation using moving sensors are presented. Special attention is paid to internal wave propagation over changing bottom topographies in shallow seas such as the Baltic Sea. The book is supplemented with an extended list of relevant and extended bibliographies, a subject index, and an author index.

Book excerpt: Internal waves exist in the ocean as a rule rather than an exception. Energy is transported by them in channels that are similar to sound channels. Their effect on naval exercises and equipment, particularly functions involving the use of underwater sound, can be expected to be more pronounced in these channels. Although theory and observation are still not adequate for a full understanding of the phenomenon, western literature prior to June 1963 contains more than 300 publications dealing with internal waves in the atmosphere, lakes, and seas. These publications are listed in the comprehensive bibliography which is part of this report. (Author).
