The Hudson River Estuary is a comprehensive look at the physical, chemical, biological and environmental management issues that are important to our understanding of the Hudson River. Chapters cover the entire range of fields necessary to understanding the workings of the Hudson River estuary; the physics, bedrock geological setting and sedimentological processes of the estuary; ecosystem-level processes and biological interactions; and environmental issues such as fisheries, toxic substances, and the effect of nutrient input from densely populated areas. This 2006 book places special emphasis on important issues specific to the Hudson, such as the effect of power plants and high concentrations of PCBs. The chapters are written by specialists at a level that is accessible to students, teachers and the interested layperson. The Hudson River Estuary is a fascinating scientific biography of a major estuary, with relevance to the study of any similar natural system in the world.

Given the realities of climate change and sea level rise, coastal cities around the world are struggling with questions of resilience. Resilience, at its core, is about desirable states of the urban social-ecological system and understanding how to sustain those states in an uncertain and tumultuous future. How do physical conditions ecological processes, social objectives, human politics, and history shape the prospects for resilience? Most books set out "the answer." This book sets out a process of grappling with holistic resilience from multiple perspectives, drawing on the insights and experiences of more than fifty Scholars and practitioners working together to make Jamaica Bay in New York-City an example for the world. Prospects for Resilience establishes a framework for understanding resilience practice in urban watersheds. Using Jamaica Bay, the largest contiguous natural area in New York, home to millions of New Yorkers, and a hub of global air travel with John F.Kennedy International Airport, the authors demonstrate how various components of social ecological systems interact, ranging from climatic factors to plant populations to human demographics. They also highlight essential tools for creating resilient Watersheds, including monitoring and identifying system indicators; computer modelling; green infrastructure; and decision science methods. Finally, they look at the role and importance of a "boundary organisation" like the new Science and Resilience Institute at Jamaica Bay in coordinating and facilitating resilience work, and consider significant research questions and prospects for the future-of urban watersheds. Prospects for Resilience sets forth an essential foundation of information and advice for researchers, urban planners, students and others who need to create more resilient cities that work with, not against, nature.
