[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)...

The Biogeography of the Australian North West Shelf provides the first assembly of existing information of the North West Shelf in terms of geological, oceanographic and climatological history and current understanding of such issues as biodiversity, connectivity, larval dispersal and speciation in the sea that determine the distribution patterns of its invertebrate fauna. It is intended as a source of information and ideas on the biota of the shelf and its evolutionary origins and affinities and the environmental drivers of species’ ecology and distribution and ecosystem function. Regulators and industry environmental managers worldwide, but especially on the resource-rich North West Shelf, are faced with having to make decisions without adequate information or understanding of conservation values or the factors that drive ecosystem processes and resilience in the face of increasing anthropogenic and natural change. This book will provide a resource of information and ideas and extensive references to issues of primary concern. It will provide a big-picture narrative, putting the marine biota into a geological, evolutionary, and regional biodiversity context. The first book to cover the major benthic habitats and physical and ecological condition of the North West Shelf of Australia Covers new information on geomorphology and biota of coral reefs and other invertebrate habitats that are key species and functional groups of the North West Shelf Introduces new ideas on biogeographic processes and patterns in tropical seas

This book was first published in 2005. When an oceanic tidal wave that is primarily active on the water surface passes an ocean shelf or a region with a seamount, it is split into a less energetic surface wave and other internal modes with different wavelengths and propagation speeds. This cascading process, from the barotropic tides to the baroclinic components, leads to the transformation of tidal energy into turbulence and heat, an important process for the dynamics of the lower ocean. Baroclinic Tides demonstrates the analytical and numerical methods used to study the generation and evolution of baroclinic tides and, by comparison with experiments and observational data, shows how to distinguish and interpret internal waves. Strongly non-linear solitary internal waves, which are generated by internal tidal waves at the final stage of their evolution, are investigated in detail. This book is intended for researchers and graduate students of physical oceanography, geophysical fluid dynamics and hydroacoustics.

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.
