Download or read book Oceanic Internal Tides Observations Analysis and Modeling written by Eugene G. Morozov and published by Springer. This book was released on 2018-02-08 with total page 304 pages. 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.
Download or read book Internal Gravity Waves written by Bruce R. Sutherland and published by Cambridge University Press. This book was released on 2010-09-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, at relatively fast temporal and small spatial scales, making them difficult to observe and resolve in weather and climate models. Solving the equations describing their evolution poses various mathematical challenges associated with singular boundary value problems and large amplitude dynamics. This book provides the first comprehensive treatment of the theory for small and large amplitude internal gravity waves. Over 120 schematics, numerical simulations and laboratory images illustrate the theory and mathematical techniques, and 130 exercises enable the reader to apply their understanding of the theory. This is an invaluable single resource for academic researchers and graduate students studying the motion of waves within the atmosphere and ocean, and also mathematicians, physicists and engineers interested in the properties of propagating, growing and breaking waves.
Download or read book Internal Gravity Waves in the Shallow Seas written by Stanisław R. Massel and published by Springer. This book was released on 2015-07-07 with total page 175 pages. 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: An unparalleled introduction to the amazing world of ocean waves. Outstanding Academic Title, Choice "Powerful ocean waves fascinate the public, and they have made a lot of news lately." With that indisputable observation, scientist J. B. Zirker takes off on a whirlwind tour of the world of waves—from the “ordinary” waves that constantly churn the sea to the rogues or freaks that can rise up seemingly from nowhere to heights of 20 meters or more . . . and everything in between. Addressing questions most ocean visitors have had and offering new ones for our consideration, The Science of Ocean Waves explains in accessible language how waves are formed, how they move, how they become huge and destructive, and how they're being studied now for clues that will help us plan for the future. Devoting chapters to wind, tides, currents, breakers, tsunamis, forecasting, renewable energy, and El Niño—as well as discussing the gentler properties of ocean waves which inspire us and offer opportunities for relaxation and recreation—Zirker explores the physical factors that create waves. Drawing on some of the recent storms that have devastated entire regions—such as Hurricane Katrina, the tsunami launched by the 2004 Sumatran earthquake, and the great tsunami that crushed the shore of Japan in 2011—Zirker explains the forces that cause these monster waves and reveals the toll they take on human lives. Enhanced by dozens of illustrations and a comprehensive glossary, The Science of Ocean Waves will fascinate anyone curious about the science behind the headlines. Praise for J. B. Zirker “Scientists know their stuff but are rarely good storytellers, whereas good storytellers rarely possess the necessary sweeping command of a scientific discipline. Zirker is that rare animal who can both communicate the most demanding technical detail and make it accessible.”—New Scientist

Download or read book Coastal Acoustic Tomography written by Arata Kaneko and published by Elsevier. This book was released on 2020-02-05 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal Acoustic Tomography begins with the specifics required for designing a Coastal Acoustic Tomography (CAT) experiment and operating the CAT system in coastal seas. Following sections discuss the procedure for data analyses and various application examples of CAT to coastal/shallow seas (obtained in various locations). These sections are broken down into four kinds of methods: horizontal-slice inversion, vertical-slice inversion, modal expansion method and data assimilation. This book emphasizes how dynamic phenomena occurring in coastal/shallow seas can be analyzed using the standard method of inversion and data assimilation. The book is relevant for physical oceanographers, ocean environmentalists and ocean dynamists, focusing on the event being observed rather than the intrinsic details of observational processes. Application examples of successful dynamic phenomena measured by coastal acoustic tomography are also included. Provides the information needed for researchers and graduate students in physical oceanography, ocean-fluid dynamics and ocean environments to apply Ocean Acoustic Tomography (OAT) to their own fields Presents the benefits of using acoustic tomography, including less disturbance to aquatic environments vs. other monitoring methods Includes the assimilation of CAT data into a coastal sea circulation model, a powerful tool to predict coastal-sea environmental changes
Download or read book Internal Wave Dynamics on the Australian North West Shelf written by Paul Van Gastel and published by . This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Internal waves are a frequently encountered phenomenon throughout the global ocean. They are generated by disturbances to a stratified ocean at frequencies between the inertial and buoyancy frequency. On continental shelf and slope regions, a common generation source is the oscillating barotropic tidal flow over varying topography, which gives rise to the internal tide. Under certain conditions, the internal tide can transform into a set of high-frequency, nonlinear internal waves. In the deep ocean, internal tides are generated at mid-oceanic topographic features. The mechanism of generation of internal waves on the shelf break and at mid-oceanic topographic features is essentially the same. The weak stratification in the deep ocean means that little energy is required here to cause significant mixing (Munk and Wunsch, 2007). Internal tides generated on the shelf break and in the deep ocean are assumed to play a very important role in dissipating tidal energy (Garrett and Kunze, 2007). Assimilation of altimeter data of tides into numerical models (Egbert & Ray 2001) showed that tides lose much more energy in the open ocean compared to coastal waters. This can be ascribed to bottom friction, generally in deep-sea regions with significant topographic features. Internal waves are studied for a variety of reasons. They provide a mechanism for the removal of energy from the barotropic tide, via the internal tide, into high-frequency internal waves, eventually to be dissipated into turbulent motions when the waves break (e.g. Kantha and Tierney, 1997). The strong horizontal currents and vertical shear associated with internal waves may destabilize underwater platforms and drilling operations for oil exploration (Bole et al, 1994). Internal waves may also cause lateral transport of nutrients (Scotti and Pineda, 2004) and the perturbations in the density field due to internal wave motions can cause large fluctuations in the sound speed and thus affect acoustic propagation which is of particular relevance to the design of sonar systems (Duda and Preisig, 1999). Observations of internal waves from field measurements and satellite imagery show the phenomenon to be highly variable in space and time and sensitive to environmental conditions with small changes producing significant changes to the internal wave strength and form. This is particularly true of the Australian North West Shelf where internal waves are known to be both ubiquitous and very energetic. This study investigates, using a comprehensive set of field observations and numerical modeling using the 3-dimensional hydrostatic ROMS model, the long-term temporal and spatial variability of the internal wave climatology on the southern region of the Australian North West Shelf (NWS)...

Download or read book Analytical and Observational Studies of Internal Solitary Waves in the Yellow Sea written by and published by . This book was released on 2006 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This article presents findings regarding the origination & evolution of a large train of internal solitary waves as observed through Synthetic Aperture Radar (SAR). The internal wave train under study propagates into deeper waters away from the coast & most important appears to be generated at a well defined point along a steep topographic variation. The shallow bottom topography revealed itself in the SAR image & provided the opportunity to determine, with a large level of accuracy, the precise area where an internal bore originated. The bore traveled east & broke up into a train of solitary waves. The packets phase speed, wave amplitude, mixed-layer depth, & density difference for a two-layer structure were remotely estimated based on measurements made from the SAR image, the knowledge of the local bathymetry, historical data & a two-layer model. Farther along the propagation path the internal waves exhibited an extremely large degree of dispersion, which was related to changing stratification conditions in the area. This particularly long train of internal waves consisted of seven packets that traveled for three days along a well-defined direction that are probably a consequence of the seasonal intrusion into the region of the low salinity plume of the Yangtze River. Monitoring changes in the dispersion characteristic of a soliton train from one tidal period to the next could render remote information regarding changing stratification condition in the area.
