Rivers provide the primary link between land and sea. Utilizing the world's largest database, this book presents a detailed analysis and synthesis of the processes affecting fluvial discharge of water, sediment and dissolved solids. It also discusses the ways in which climatic variation, episodic events and anthropogenic activities - past, present and future - affect the quantity and quality of river discharge. The book contains more than 165 figures - many in full color - including global and regional maps. An extensive appendix presents the 1534-river database as a series of 44 tables that provide quantitative data regarding the discharge of water, sediment and dissolved solids. The complete database is also presented within a GIS-based package available online at www.cambridge.org/milliman. Now available in paperback, reprinted with corrections, this is an invaluable resource for researchers, professionals and graduate students in hydrology, oceanography, geology, geomorphology and environmental policy.

As people come to realize the importance of the environmental impact of human activities, the study of the coastal zone has become increasingly important. In addition, new environmental legislation at regional, national, and international levels will doubtless highlight the importance of a fuller understanding of the coastal areas. Together, these factors have led to substantial new requirements for the acquisition and monitoring of relevant environmental information and for a fuller understanding of the processes at work-work for which the use of remote sensing techniques is essential. To meet the requirements of this emerging discipline, Physical Processes in the Coastal Zone: Computer Modelling and Remote Sensing integrates basic physical processes with extensive information from remote sensing systems such as those on aircraft and spacecraft. It covers the physical processes that occur in the coastal zone, an area in which 60% of the world's population live. Written by international experts, the text provides a comprehensive, graduate-level introduction and overview that is suitable both for those entering the field and for those already working within it.

Rivers smaller than the Amazon tend to be excluded from earth system modeling efforts. Does it matter? Do sub-grid-scale rivers have significant impacts on offshore primary productivity? Using the Eel River in northern California, the river with the largest sediment yield per drainage area in the continental United States, as a test case, this question is explored using two approaches. First, a data-driven analysis of relevant time series taken on land, by buoy, and from space, demonstrates very little evidence of direct impact of Eel River discharge on contemporaneous coastal ocean primary productivity - but to the extent that that evidence exists, it seems to occur during years of greatest river discharge. To further analyze mechanistic drivers, a coupled mesoscale modeling framework unifying ocean, watershed and atmospheric representations is formulated and run in hindcast over the 2002-2010 period. Monthly average climatologies, interannual variabilities, and event-driven analysis of each year's largest river discharge are all examined for evidence of a river-ocean connection expressed through primary production. Storm event-generated turbulence appears to dominate the primary productivity during the winter months. The impact of the river seems to be largely independent of nutrient load, because its dissolved nitrate is less than that of the coastal ocean. There is no evidence that riverine delivery of gradually bioavailable detritus has a significant effect. Although a sufficiently super-nitrous river shows the ability to sustain a plume-nutrient-driven-bloom even at periods of extremely low flow, this is not currently a realistic scenario for the Eel River. The possibility remains that another micronutrient not studied in the modeling framework, such as iron, could be important to this system.

In multidisciplinary efforts to understand and manage our planet, contemporary ocean science plays an essential role. Volumes 13 and 14 of The Sea focus on two of the most important components in the field of ocean science today—the coastal ocean and its interactions with the deep sea, and coupled physical-biogeochemical and ecosystem dynamics.

Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 56. Coastal Ocean Prediction is being published during a period when operational coastal ocean prediction systems are emerging in Europe, Asia, Australia, and North America. Some of these systems are linked to activities of the Global Ocean Observing System, sponsored by the Intergovernmental Oceanographic Commission, World Meteorological Organization, United Nations Environmental Program, and the International Council of Scientific Unions. The Global Ocean Observing System is itself an emergent program of model?]based operational (i.e., continual and governmentally sanctioned) monitoring with coastal ocean, as well as fully global, components.

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.
