The explosion of interest, effort, and information about the ocean since about 1950 has produced many thousand scientific articles and many hun dred books. In fact, the outpouring has been so large that authors have been unable to read much of what has been published, so they have tended to concentrate their own work within smaller and smaller subfields of oceanog raphy. Summaries of information published in books have taken two main paths. One is the grouping of separately authored chapters into symposia type books, with their inevitable overlaps and gaps between chapters. The other is production of lightly researched books containing drawings and tables from previous pUblications, with due credit given but showing assem bly-line writing with little penetration of the unknown. Only a few books have combined new and previous data and thoughts into new maps and syntheses that relate the contributions of observed biological, chemical, geological, and physical processes to solve broad problems associated with the shape, composition, and history of the oceans. Such a broad synthesis is the objective of this book, in which we tried to bring together many of the pieces of research that were deemed to be of manageable size by their originators. The composite may form a sort of plateau above which later studies can rise, possibly benefited by our assem bly of data in the form of new maps and figures.

Presents an illustrated examination of the Atlantic Ocean and the transformative role it has played as a corridor for the exchange of people, technologies, ideas, goods, and cultures for over two thousand years as exploration and discovery helped in the growth of global commerce.

In this highly illustrated book Barry Cunliffe focuses on the western rim of Europe--the Atlantic facade--an area stretching from the Straits of Gibraltar to the Isles of Shetland.We are shown how original and inventive the communities were, and how they maintained their own distinctive identities often over long spans of time. Covering the period from the Mesolithic hunter-gatherers, c. 8000 BC, to the voyages of discovery c. AD 1500, he uses this last half millennium more as a well-studied test case to help the reader better understand what went before. The beautiful illustrations show how this picturesque part of Europe has many striking physical similarities. Old hard rocks confront the ocean creating promontories and capes familiar to sailors throughout the millennia. Land's End, Finistere, Finisterra--until the end of the fifteenth century this was where the world ended in a turmoil of ocean beyond which there was nothing. To the people who lived in these remote placesthe sea was their means of communication and those occupying similar locations were their neighbours. The communities frequently developed distinctive characteristics intensifying aspects of their culture the more clearly to distinguish themselves from their in-land neighbours. But there is an added level of interest here in that the sea provided a vital link with neighbouring remote-place communities encouraging a commonality of interest and allegiances. Even today the Bretons see themselvesas distinct from the French but refer to the Irish, Welsh, and Galicians as their brothers and cousins. Archaeological evidence from the prehistoric period amply demonstrates the bonds which developed and intensified between these isolated communities and helped to maintain a shared but distinctive Atlantic identity.

This book is dedicated to the study of structure and transport of deep and bottom waters above and through underwater channels of the Atlantic Ocean. The study is based on recent observations, analysis of historical data, and literature reviews. This approach allows us to understand how water transport and water mass prop- ties have changed over the last years and decades. The focus of our study is on the propagation of bottom waters in the Atlantic Ocean based on new field data at key points. At the end of the 1920s, the first integral study of water masses and bottom topography of the Central and South Atlantic was carried out from the German - search vessel Meteor. This German Atlantic Expedition was one of the first cruises equipped with the newly developed echo sounder (fathometer): an obligatory p- requisite for the investigation of bottom morphology in the deep sea on an - erational base. The results of the expedition were published by Wüst, Defant, and colleagues in the multivolume METEOR publication series starting with the cruise report by the ship’s commander (Spiess 1928, 1932). Historically, this series of p- lications, intermittently interrupted by World War II, was the basis for many years of research into the development of modern concepts about Atlantic water masses and their circulation schemes.

This book explains the use and techniques of paleomagnetism to map the movement of major portions of the Earth's surface through time. Written for a geological audience, the initial chapters provide the basic essentials for understanding the value and significance of paleomagnetic results. The later chapters are unique in bringing together the vast amounts of available paleomagnetic data and analyses. This information is integrated with the paleogeography and tectonic movements of the blocks and placed in context with current tectonic hypotheses. A considerable proportion of the present continents are considered - that is the land areas that are now found around the Atlantic and Indian Oceans and in Asia. Also presented is an extensive catalogue of paleomagnetic results for all major continents and the displaced elements that they contain.

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.
