Book Description
The South China Sea (SCS), Yellow/East China Sea (YES), and Japan/East Sea (JES) are major east Asian marginal seas (EAMS). The complex topography includes the broad shallows of the Sunda Shelf in the south/southwest of SCS; the continental shelf of the Asian landmass in the north, extending from the Gulf of Tonkin to the YES; a deep, elliptical shaped SCS and JES basins, and numerous reef islands and underwater plateaus scattered throughout (Fig. 1a). The shelf that extends from the Gulf of Tonkin to the YES is consistently near 70 m deep, and averages 150 km in width. The EAMS is subjected to a seasonal monsoon system. From April to August, the weaker southwesterly summer monsoon winds result in a wind stress of just over 0.1 N/m2. From November to March, the stronger northeasterly winter monsoon winds corresponds to a maximum wind stress of nearly 0.3 N /m2. Recent observational studies show that the EAMS is energetic and has multi-eddy structure. For example, the SCS synoptic eddy structure was identified in May 1995 using the airborne expendable bathythermograph (AXBT) data (Chu et al., 1998a), the eddy spatiotemporal scales in the YES were identified using the Navy's Master Oceanographic Observational Data Set (MOODS) during 1929- 1991 (Chu et al., 1997a, b), and the seasonal JES multi-eddy structure from a composite analysis on the U.S. National Centers for Environmental Prediction (NCEP) monthly SST fields during 1981-1994 (Chu et al. 1998b).

Book Description
The goals ofthe Symposium were to highlight advances in modelling ofatmosphere and ocean dynamics, to provide a forum where atmosphere and ocean scientists could present their latest research results and learn ofprogress and promising ideas in these allied disciplines; to facilitate interaction between theory and applications in atmosphere/ocean dynamics. These goals were seen to be especially important in view ofcurrent efforts to model climate requiring models which include interaction between atmosphere, ocean and land influences. Participants were delighted with the diversity ofthe scientific programme; the opportunity to meet fellow scientists from the other discipline (either atmosphere or ocean) with whom they do not normally interact through their own discipline; the opportunity to meet scientists from many countries other than their own; the opportunity to hear significant presentations (50 minutes) from the keynote speakers on a range ofrelevant topics. Certainly the goal ofcreating a forum for exchange between atmosphere and ocean scientists who need to input to create realistic models for climate prediction was achieved by the Symposium and this goal will hopefully be further advanced by the publication ofthese Proceedings.

Book Description
The East Asian Seas (EAS) model is a regional application of the Navy Coastal Ocean Model (NCOM) in the Western Pacific (WESTPAC). The EAS model domain includes the South China Sea, the East China Sea, and the Japan/East Sea. This model was developed by the Naval Research Laboratory (NRL) as part of a forecast system to predict ocean currents, temperature, salinity, and elevation for the WESTPAC region. This forecast system addresses the Navy requirements for Littoral Salinity Prediction (METOC 9902), Numerical Modeling (METOC 9801), High Resolution Surface and Subsurface Currents (METOC 9308), and Air-Sea Drift Prediction (METOC 9115). The EAS model is scheduled for transition into operations at the Naval Oceanographic Office in 2006. This validation test report will describe the EAS forecast system and discuss the evaluation of this system performed by NRL including comparison to observations as well as other Navy operational forecast systems in the WESTPAC region. Other detailed descriptions of the EAS forecast system are available from the EAS Software Design Description (SSD), Software Requirements Specification (SRS), Software Test Description (STD), and User's Manual (UM).

Book Description
A major task for physical oceanographers is to determine the movement of oceanic water from observations. This book introduces the P-vector inverse method, with a two-step determination of the velocity from hydrographic data. The book provide insights into the basics of the P-vector inverse method and the features of the inverted global and regional ocean circulations. Upper undergraduate and graduate students as well as oceanographers, marine biologists and other environmental scientists will find this book a valuable tool for their studies.

Book Description
The TOGA (Tropical Ocean and Global Atmosphere) Program was designed to study short-term climate variations. A 10-year international program, TOGA made El Nino a household word. This book chronicles the cooperative efforts of oceanographers and meteorologists, several U.S. government agencies, many other nations, and international scientific organizations to study El Nino and the Southern Oscillation (ENSO). It describes the progression from being unable to detect the development of large climate variations to being able to make and use rudimentary climate predictions, especially for some tropical countries. It examines the development of the TOGA Program, evaluates its accomplishments, describes U.S. participation in the program, and makes general recommendations for developing better understanding and predictions of climate variations on seasonal to interannual time scales.

Book Description
The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Book Description
An interdisciplinary study of the Kuroshio nutrient stream The surface water of the Kuroshio, a western boundary current in the North Pacific Ocean, is nutrient-depleted and has relatively low primary productivity, yet abundant fish populations are supported in the region. This is called the “Kuroshio Paradox”. Kuroshio Current: Physical, Biogeochemical and Ecosystem Dynamics presents research from a multidisciplinary team that conducted observational and modeling studies to investigate this contradiction. This timely and important contribution to the ocean sciences literature provides a comprehensive analysis of the Kuroshio. Volume highlights include: New insights into the role of the Kuroshio as a nutrient stream The first interdisciplinary examination of the Kuroshio Paradox Reflections on the influence of the Kuroshio on Japanese culture Research results on both the lower and higher trophic levels in the Kuroshio ecosystem Comparisons of nutrient dynamics in the Kuroshio and Gulf Stream Predictions of ecosystem responses to future climate variability

Book Description
This book offers a comprehensive overview of the models and methods employed in the rapidly advancing field of numerical ocean circulation modeling. For those new to the field, concise reviews of the equations of oceanic motion, sub-grid-scale parameterization, and numerical approximation techniques are presented and four specific numerical models, chosen to span the range of current practice, are described in detail. For more advanced users, a suite of model test problems is developed to illustrate the differences among models, and to serve as a first stage in the quantitative evaluation of future algorithms. The extensive list of references makes this book a valuable text for both graduate students and postdoctoral researchers in the marine sciences and in related fields such as meteorology, and climate and coupled biogeochemical modeling.
