Oceanic Internal Waves and Internal Tides in the East Asian Marginal Seas by Xueen Chen,SungHyun Nam Pdf

Oceanic internal waves (IWs) at frequencies from local inertial (e.g., near-inertial internal waves) to buoyancy frequencies (nonlinear internal waves or internal solitary waves), sometimes including diurnal and semidiurnal tidal frequencies, play an important role in redistributing heat, momentum, materials, and energy via turbulent mixing. IWs are found ubiquitously in many seas, including East Asian marginal seas (Indonesian Seas, South China Sea, East China Sea, Yellow Sea, and East Sea or Japan Sea), significantly affecting underwater acoustics, coastal and offshore engineering, submarine navigation, biological productivity, and the local and global climate. Despite decades of study on the IWs in some regions, our understanding of the IWs in the East Asian marginal seas is still in a primitive state and the mechanisms underlying every stage (generation, propagation, evolution, and dissipation) of IWs are not always clear. This Special Issue includes papers related to all fields of both low- and high-frequency IW studies in the specified region, including remote sensing, in situ observations, theories, and numerical models.

Oceanic Internal Tides: Observations, Analysis and Modeling by Eugene G. Morozov Pdf

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.

Oceanography of Asian Marginal Seas by K. Takano Pdf

This volume contains 31 papers on physical and geological oceanography, marine engineering and meterology in the Japan Sea and the East China Sea. Almost all these papers were presented at the Fifth JECSS (Japan and East China Seas Study) Workshop held in Korea in 1989. Results of multinational cooperative studies carried out since the initiation of JECSS in 1981 are presented. Authors are from China, Japan, Korea, UK, USA and USSR. A wide range of subjects are covered from the viewpoint of various disciplines. The status of recent research on Asian marginal seas is outlined and points at issue are defined. An important aspect is the coverage of results from the USSR and China which are not normally easily accessible to scientists in other countries, despite the importance of this research to the international scientific community. Various subjects, from estuaries to the problems related to the whole north Pacific, are covered in this book, and it is recommended to scientists in coastal oceanography, environmental oceanography, mesoscale (synoptic scale) oceanography and large-scale oceanography.

Observations and Modeling of the Internal Tide in a Submarine Canyon by Emil T. Petruncio Pdf

Shipboard ADCP and CTD measurements were conducted in Monterey Submarine Canyon in April and October 1994 to determine the propagation characteristics and energy levels of the semidiurnal internal tide. The measurements reveal a bottom intensified internal tide propagating energy up canyon. The region of strongest motion is in a beam 150-200 m thick, centered approximately 150 m above the Canyon floor. Along canyon baroclinic M2 currents are typically 15-20 cm/s, an order of magnitude larger than the estimated barotropic tidal currents. In April 1994, the internal tidal beam is well described by a progressive wave, while in October 1994, the signal is standing along and perpendicular to the beam. The Princeton Ocean Model was used to study the generation and propagation of semidiurnal internal tides in submarine canyons and to investigate their sensitivity to canyon shape.

On the Reality of Internal Lunar Tidal Waves in the Ocean by Bernhard Haurwitz Pdf

The temperature soundings made by the Atlantis at an anchor station north of Bermuda from 16 to 29 June 1938 are analyzed in order to determine whether any diurnal or semidiurnal lunar internal tidal oscillations were present in the observational material. It is concluded that the oscillations which are computed by harmonic analysis are not larger than can be expected in random data. This result suggests that some of the reported occurrences of similar internal waves of tidal character in short series of observations are not real, but merely due to the formal harmonic analysis of the data. However, since in many instances the existence of internal tidal waves has been established beyond doubt, the problem arises to explain which conditions are favorable and unfavorable to the development of such phenomena in the ocean. Various reasons are suggested which may explain the absence of internal tidal waves in the present observation material. (Author).

Observation of High Frequency Internal Waves in the Pacific Ocean by Robert Libman Zalkan Pdf

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).
