This is an invaluable textbook, prepared by the Open University team and designed so that it can be read on its own or as part of the OU course. This second edition has been fully revised and updated including new colour illustrations increasing the striking spread of full colour diagrams throughout the book. The clarity of the text has been improved, providing comprehensive coverage of the evolution of ocean basins and their structure in a clear, concise manner aimed specifically at the student market. In this second edition the technological advances in fields as diverse as: - deep-towed instruments for `sniffing' hydrothermal plumes - mapping the sea-floor by sophisticated sonar techniques - three-dimensional imaging of crustal structure by seismic tomography - the use of satellites for navigation, and for making precise measurements of the height of the sea-surface The first chapters describe the processes that shape the ocean basins, determine the structure and composition of oceanic crust and control the major features of continental margins. How the 'hot springs' of the oceanic ridges cycle chemical elements between seawater and oceanic crust is then explored. Sediment distributions are examined next, to demonstrate how sediments can preserve a record of past climatic and sea-level changes. Finally, the role of the oceans as an integral part of global chemical changes is reviewed. High quality full colour diagrams Substantial chapter summaries ideal for revision Answers, hints and notes for questions at back of the book
This Volume describes the processes that shape ocean basins, determine the structure and composition of the ocean crust, and control the major features of the continental margins. Further subjects examined are the 'hot springs' of the deep oceans, the main pattern of sediment distribution in ocean basins including the recording of past climatic and sea-level changes, and the role of oceans as an integral part of global chemical cycles. Each Volume in this set is well laid out and copiously illustrated with full colour photographs, graphs and graphics. Questions to help develop arguments and/or understanding can be found in the text and at the end of each chapter, with worked answers provided at the back of each Volume. Each chapter also concludes with a sum mary to help consolidate understanding before the next chapter is begun.
This work provides a wide perspective of the oceans by examining their places in the earth sciences, drawing together all the key strands of ocean study and presenting a holistic view of ocean processes, ancient and modern.
This major textbook provides a broad coverage of the ecological foundations of marine conservation, including the rationale, importance and practicalities of various approaches to marine conservation and management. The scope of the book encompasses an understanding of the elements of marine biodiversity - from global to local levels - threats to marine biodiversity, and the structure and function of marine environments as related to conservation issues. The authors describe the potential approaches, initiatives and various options for conservation, from the genetic to the species, community and ecosystem levels in marine environments. They explore methods for identifying the units of conservation, and the development of defensible frameworks for marine conservation. They describe planning of ecologically integrated conservation strategies, including decision-making on size, boundaries, numbers and connectivity of protected area networks. The book also addresses relationships between fisheries and biodiversity, novel methods for conservation planning in the coastal zone and the evaluation of conservation initiatives.
A new approach to the development and management of environmentally sustainable and socially relevant technologies in the marine sector through new forms of private and public international cooperation. Deals with the most fundamental aspect of the development gap between the North and the South - the "technology gap". As technological innovation based on research and development is the engine which drives economic growth and most developing countries are left out of research and development in high technology, it is difficult to narrow the economic development gap, thus reducing poverty. It is of paramount importance that this gap be narrowed if both environmental and international security is to be increased. This book emphasises the development of human resources in technology co-development, moving from traditional to contemporary to futuristic concepts, and makes a number of concrete recommendations which should be on the development-environment agenda for the 1990's.

The rapidly developing field of oceanography has necessitated the publication of a fifth edition of this classic textbook. The revised version provides an introduction to descriptive (synoptic) oceanography and contains updated information on topics such as the heat budget, instruments and in particular, the use of satellites. The sections on equatorial oceanography, sea-ice physics, distribution and El Nino have been completely rewritten. The book is further supplemented by text on thermohaline circulation, mixing and also coral reef oceanography.
Revised for increased readability, this full-colour text offers an insightful, ecologically-sensitive presentation of the relationship of scientific principles to ocean phenomena. Now better suited for non-major oceanography courses, this edition offers a broader study with a marked reduction in concentrated topic coverage, with a continued emphasis on how we must take more precautions in activities that can modify the environment and learn how to keep these modifications to a minimum.
