Wave breaking is a commonly occurring phenomena associated with wave motion in fluids, often inducing significant effects which are of fundamental and technological importance, A familiar illustration is provided with white-capping and microbreaking of the wind-driven ocean sUrface waves, which is believed to play an important part in the transfers of momentum, mass and heat across the air-sea interface, as well as in the production of underwater ambient noise and augmented microwave backscatter. The enhanced hydrodynamic forces associated with the breaking of the more energetic ocean wave components constitute a significant challenge in ocean engineering, coastal engineering and naval architecture. Other less conspicuous but equally important manifestations are the breaking of internal waves and the fila mentation of vorticity interfaces. Despite recent theoretical and observational progress towards a more complete understanding of wave breaking, mathematical descriptions of its onset and consequences are presently lacking. The aim of this Symposium was to bring together theoretical and observational expertise, with the goal of determining the current state of knowledge of wave breaking and providing a stimulus to future research. The Symposium focused on water waves of all scales from capillary waves to ocean swell, but also considered internal waves and the filamentation of vorticity interfaces. Specific topics included were: Fundamental theoretical studies; wave instabilities; routes to breaking. Models of wave breaking. Field observations, including statistical information. Laboratory studies. Shoaling waves, breaking waves on currents, breaking induced by the motion of a ship.

[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 dynamics of flows in density-stratified fluids has been and remains now an important topic for scientific enquiry. Such flows arise in many contexts, ranging from industrial settings to the oceanic and atmospheric environments. It is the latter topic which is the focus of this book. Both the ocean and atmosphere are characterised by the basic vertical density stratification, and this feature can affect the dynamics on all scales ranging from the micro-scale to the planetary scale. The aim of this book is to provide a “state-of-the-art” account of stratified flows as they are relevant to the ocean and atmosphere with a primary focus on meso-scale phenomena; that is, on phenomena whose time and space scales are such that the density stratification is a dominant effect, so that frictional and diffusive effects on the one hand and the effects of the earth’s rotation on the other hand can be regarded as of less importance. This in turn leads to an emphasis on internal waves.
