Book Description
This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

Book Description
Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.

Book Description
Conventional management approaches cannot meet the challenges faced by ocean and coastal ecosystems today. Consequently, national and international bodies have called for a shift toward more comprehensive ecosystem-based marine management. Synthesizing a vast amount of current knowledge, Ecosystem-Based Management for the Oceans is a comprehensive guide to utilizing this promising new approach. At its core, ecosystem-based management (EBM) is about acknowledging connections. Instead of focusing on the impacts of single activities on the delivery of individual ecosystem services, EBM focuses on the array of services that we receive from marine systems, the interactive and cumulative effects of multiple human activities on these coupled ecological and social systems, and the importance of working towards common goals across sectors. Ecosystem-Based Management for the Oceans provides a conceptual framework for students and professionals who want to understand and utilize this powerful approach. And it employs case studies that draw on the experiences of EBM practitioners to demonstrate how EBM principles can be applied to real-world problems. The book emphasizes the importance of understanding the factors that contribute to social and ecological resilience —the extent to which a system can maintain its structure, function, and identity in the face of disturbance. Utilizing the resilience framework, professionals can better predict how systems will respond to a variety of disturbances, as well as to a range of management alternatives. Ecosystem-Based Management for the Oceans presents the latest science of resilience, while it provides tools for the design and implementation of responsive EBM solutions.

Book Description
In The Empty Ocean, acclaimed author and artist Richard Ellis tells the story of our continued plunder of life in the sea and weighs the chances for its recovery. Through fascinating portraits of a wide array of creatures, he introduces us to the many forms of sea life that humans have fished, hunted, and collected over the centuries, from charismatic whales and dolphins to the lowly menhaden, from sea turtles to cod, tuna, and coral. Rich in history, anecdote, and surprising fact, Richard Ellis’s descriptions bring to life the natural history of the various species, the threats they face, and the losses they have suffered. Killing has occurred on a truly stunning scale, with extinction all too often the result, leaving a once-teeming ocean greatly depleted. But the author also finds instances of hope and resilience, of species that have begun to make remarkable comebacks when given the opportunity. Written with passion and grace, and illustrated with Richard Ellis’s own drawings, The Empty Ocean brings to a wide audience a compelling view of the damage we have caused to life in the sea and what we can do about it.

Lawrence grew up on the long peninsula, and though he is a professional historian, they say that Carol brought a degree of detachment and scholarship that prevented the account from being a personal memoir. They describe the transformation of the urban community in southern Queens during the decades immediately after World War II. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).

Book Description
In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a major, coordinated, international program of ocean exploration and discovery. The study committee surveys national and international ocean programs and strategies for cooperation between governments, institutions, and ocean scientists and explorers, identifying strengths, weaknesses, and gaps in these activities. Based primarily on existing documents, the committee summarizes priority areas for ocean research and exploration and examines existing plans for advancing ocean exploration and knowledge.
