Oceans play a pivotal role in our weather and climate. Ocean-borne commerce is vital to our increasingly close-knit global community. Yet we do not fully understand the intricate details of how they function, how they interact with the atmosphere, and what the limits are to their biological productivity and their tolerance to wastes. While satellites are helping us to fill in the gaps, numerical ocean models are playing an important role in increasing our ability to comprehend oceanic processes, monitor the current state of the oceans, and to a limited extent, even predict their future state.Numerical Models of Oceans and Oceanic Processes is a survey of the current state of knowledge in this field. It brings together a discussion of salient oceanic dynamics and processes, numerical solution methods, and ocean models to provide a comprehensive treatment of the topic. Starting with elementary concepts in ocean dynamics, it deals with equatorial, mid-latitude, high latitude, and coastal dynamics from the perspective of a modeler. A comprehensive and up-to-date chapter on tides is also included. This is followed by a discussion of different kinds of numerical ocean models and the pre- and post-processing requirements and techniques. Air-sea and ice-ocean coupled models are described, as well as data assimilation and nowcast/forecasts. Comprehensive appendices on wavelet transforms and empirical orthogonal functions are also included.This comprehensive and up-to-date survey of the field should be of interest to oceanographers, atmospheric scientists, and climatologists. While some prior knowledge of oceans and numerical modeling is helpful, the book includes an overview of enough elementary material so that along with its companion volume, Small Scale Processes in Geophysical Flows, it should be useful to both students new to the field and practicing professionals.* Comprehensive and up-to-date review* Useful for a two-semester (or one-semester on selected topics) graduate level course* Valuable reference on the topic* Essential for a better understanding of weather and climate

Ocean Mixing: Drivers, Mechanisms and Impacts presents a broad panorama of one of the most rapidly-developing areas of marine science. It highlights the state-of-the-art concerning knowledge of the causes of ocean mixing, and a perspective on the implications for ocean circulation, climate, biogeochemistry and the marine ecosystem. This edited volume places a particular emphasis on elucidating the key future questions relating to ocean mixing, and emerging ideas and activities to address them, including innovative technology developments and advances in methodology. Ocean Mixing is a key reference for those entering the field, and for those seeking a comprehensive overview of how the key current issues are being addressed and what the priorities for future research are. Each chapter is written by established leaders in ocean mixing research; the volume is thus suitable for those seeking specific detailed information on sub-topics, as well as those seeking a broad synopsis of current understanding. It provides useful ammunition for those pursuing funding for specific future research campaigns, by being an authoritative source concerning key scientific goals in the short, medium and long term. Additionally, the chapters contain bespoke and informative graphics that can be used in teaching and science communication to convey the complex concepts and phenomena in easily accessible ways. - Presents a coherent overview of the state-of-the-art research concerning ocean mixing - Provides an in-depth discussion of how ocean mixing impacts all scales of the planetary system - Includes elucidation of the grand challenges in ocean mixing, and how they might be addressed

One of the most crucial but still very poorly understood topics of oceanographic science is the role of ocean processes in contributing to the dynamics of climate and global change. This book presents a series of high level lectures on the major categories of ocean/atmosphere processes. Three of these major issues are the focus of the lectures: (1) air--sea interaction processes; (2) water mass formation, dispersion and mixing; (3) general circulation, with specific emphasis on the thermohaline component. Global examples in the world ocean are provided and discussed in the lectures. In parallel, the Mediterranean Sea is a laboratory basin in providing analogues of the above global processes relevant to climate dynamics. They include the Mediterranean thermohaline circulation with its own `conveyor belt'; intermediate and deep water mass formation and transformations, dispersion and mixing. No other book in the field provides a review of fundamental lectures on these processes, coupled with global examples and their Mediterranean analogues.

Marine Ecological Processes is a modern review and synthesis of marine ecology that provides the reader - particularly the graduate student - with a lucid introduction to the intellectual concepts, approaches, and methods of this evolving discipline. Comprehensive in its coverage, this book focuses on the processes controlling marine ecosystems, communities, and populations and demonstrates how general ecological principles - derived from terrestrial and freshwater systems as well - apply to marine ecosystems. Numerous illustrations, examples, and references clearly impart to the reader the current state of research in this field; its achievements as well as unresolved controversies.

This book reviews and summarizes the results and hypotheses raised by studies directly or indirectly dealing with the ecology of fronts and aims to identify the themes that connect them to produce a synthesis of this knowledge. Though not immediately perceived the ocean is highly structured and fronts are one of the most important components of its structural complexity. Marine fronts have been known since the early 20th Century, however, the more recent availability of high resolution satellite imagery, field measurements and numerical simulations have greatly advanced our understanding of their ecological impact. This work touches on topics such as front types, its biology and its comparisons with other bounderies at sea, as well as comparisons of fronts with terrestrial boundaries and the ‘ecotone’ concept. Furthermore, it also looks at the management and conservation of marine life.

On May 25, 1977 a small invited group of coastal oceanographers assembled at the Marine Sciences Research Center at Stony Brook for three days of intensive discussions in a cloistered setting. The purpose of this workshop was to "assess the state of the art, to ascertain priorities for future research and to formulate the theoretical, instrumen tal, experimental and logistical tools needed to attain those goals in the study of coastal oceanic* fronts. " Although the existence of oceanic fronts has been known for a long time, ocean frontology is experiencing rapid acceleration in the emergence of new concepts and methodology. The science is developing from the descriptive phase and many unsolved problems lie in the understanding and quantification of frontal dynamics. In turn, challenging questions need to be addressed on the controlling influence of the physics of fronts on the chemistry, biology, acoustics, and suspended particulate aggregations in these zones. Coastal fronts are very efficient at concentrating buoyant and suspended particulate matter inclUding toxic wastes; heavy metal concentrations in polluted coastal frontal zones have been measured to be as high as one to ten thousand times background. These zones are also regions of high biological productivity, and consequently frequented by both commercial and sports fishermen.
