Deep Ocean Circulation by T. Teramoto Pdf

This volume comprises the final report of the research project entitled the Dynamics of the Deep Ocean Circulation. The layered structure of the subsurface circulation, which had been predicted in the hypothetical model proposed prior to the research, is verified through Eulerian and Lagrangian measurements of current. By the use of the numerical model, the deep circulation of the Philippine Sea, which has been long supposed to be isolated from the North Pacific, is revealed to be derived in close association with that of the latter ocean. Behavior of the deep current around the equator is also clarified by numerical modeling. By the extensive use of sediment trapping technology, it becomes clear that sinking sediments play an important role in the distribution of chemical substances in the deep ocean. Graduate students in the field of oceanography will find this a good textbook.

Ocean Circulation and Climate by John L. Bullister,Monika Rhein,Cecilie Mauritzen Pdf

Formation of the deepest waters of the World Ocean occurs in limited regions of the global ocean, primarily in the northern North Atlantic where North Atlantic Deep Water (NADW) is formed, and at a number of sites around the continental margins of Antarctica where Antarctic Bottom Waters (AABW) are formed. The deepwater formation processes play a significant role in determining the large-scale physical and biogeochemical properties of the deep ocean. These limited regions provide a conduit from the surface into the vast volumes of water in the deep ocean. We report in this chapter on observed physical and biochemical changes in the deep ocean and discuss these in the context of deepwater formation. Intensive observation programs in the North Atlantic during the past decades have demonstrated that there have been significant changes in the volumes and properties of Upper and Lower NADW as well as AABW. Studies have found systematic warming of AABW during the past two decades along a number of its major flow pathways, as well as evidence for a reduction in overall volume of AABW in the global deep ocean. Lower NADW, on the other hand, has been undergoing systematic cooling for the past four decades, whereas Upper NADW (primarily Labrador Sea Water) has been exposed to large decadal variability, both in properties and formation rates. In total, the deepwaters of the World Ocean (beneath ca. 2000–3000m) have warmed during the past two decades. Changes in the deep ocean can have enormous influence on Earth’s climate. Warming of the deep ocean makes a significant contribution to global sea level rise. The capacity of the deep ocean to take up and store anthropogenic CO2 has and will have a major impact on the CO2 content of the atmosphere now and far into the future. Paleooceanographic studies have provided evidence that despite the century-long timescales associated with renewal of deepwater, rapid, major changes in deepwater formation and deep ocean circulation have occurred in the past, resulting in rapid changes in Earth’s climate. Continued monitoring and analysis are necessary to follow and understand the changes in the deep ocean—this is a very important component of Earth’s climate.

The Ocean in Motion by Manuel G. Velarde,Roman Yu. Tarakanov,Alexey V. Marchenko Pdf

This book commemorates the 70th birthday of Eugene Morozov, the noted Russian observational oceanographer. It contains many contributions reflecting his fields of interest, including but not limited to tidal internal waves, ocean circulation, deep ocean currents, and Arctic oceanography. Special attention is paid to studies on internal waves and especially those on tidal internal waves in the Global Ocean. These papers describe the most important open problems concerning experimental studies of internal waves and their theoretical, numerical, and laboratory modeling. Further contributions investigate the physics of surface waves and their interaction with internal waves. Here, the focus is on describing interaction processes between internal waves and deep currents in the ocean, especially currents of Antarctic Bottom Water in abyssal fractures. They also touch on the problem of oceanic circulation and related processes in fjords, including those occurring under sea ice. Given its breadth of coverage, the book will appeal to anyone interested in a survey of ocean dynamics, ranging from historic perspectives to modern research topics.

Deep Convection and Deep Water Formation in the Oceans by P. C. Chu,Jean-Claude Gascard Pdf

This book contains articles presenting current knowledge about the formation and renewal of deep waters in the ocean. These articles were presented at an international workshop at the Naval Postgraduate School in Monterey in March 1990. It is the first book entirely devoted to the topic of deep water formation in which articles have been both selected and reviewed, and it is also the first time authors have addressed both surface and deep mixed layers. Highlighted are: past and recent observations (description and analysis), concepts and models, and modern techniques for future research. Thanks to spectacular advances realised in computing sciences over the last twenty years this volume includes a number of sophisticated numerical models. Observational as well as theoretical studies are presented and a clear distinction is established between open-ocean deep convection and shelf processes, both leading to deep- and bottom-water formation. The main subject addressed is the physical mechanism by which the deep water in the ocean can be renewed. Ventilation occurs at the surface in areas called the gills , where water is mixed and oxygenated before sinking and spreading in the abyss of the deep ocean. This phenomenon is a very active area for both experimentalists and theoreticians because of its strong implications for the understanding of the world ocean circulation and Earth climate. This major theme sheds light on specific and complex processes happening in very restricted areas still controlling three quarters of the total volume of the ocean. All articles include illustrations and a bibliography. This book will be of particular interest to physical oceanographers, earth scientists, environmentalists and climatologists.

Bottom Gravity Currents and Overflows in Deep Channels of the Atlantic Ocean by Eugene G. Morozov,Roman Y. Tarakanov,Dmitry I. Frey Pdf

This book is dedicated to the analysis of bottom waters flows through underwater channels of the Atlantic Ocean. The study is based on recent observations of the authors, analysis of historical data, numerical modeling, and literature review. For example, studying both the measurements from the World Ocean Circulation experiment in the 1990s and recent measurements reveals the decadal variations of water properties in the ocean. Seawater is cooled at high latitudes, descends to the ocean bottom, and slowly flows to the tropical latitudes and further. This current is slow in the deep basins, but intensifies in the abyssal channels connecting the basins. The current overflows submarine topographic structures and sometimes forms deep cataracts when water descends over slopes by several hundred meters. The flow of Antarctic Bottom Water (AABW) is studied on the basis of CTD sections combined with Lowered Acoustic Doppler Profiling (LADCP) carried out annually, and long-term moored measurements of currents. This book is a collection of oceanographic data, interpretation, and analysis, which can be used by field oceanographers, specialists in numerical modeling, and students who specialize in oceanography.

Ocean Circulation by Andreas Schmittner,John C. H. Chiang,Sidney R. Hemming Pdf

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 173. The ocean's meridional overturning circulation (MOC) is a key factor in climate change. The Atlantic MOC, in particular, is believed to play an active role in the regional and global climate variability. It is associated with the recent debate on rapid climate change, the Atlantic Multi-Decadal Oscillation (AMO), global warming, and Atlantic hurricanes. This is the first book to deal with all aspects of the ocean's large-scale meridional overturning circulation, and is a coherent presentation, from a mechanistic point of view, of our current understanding of paleo, present-day, and future variability and change. It presents the current state of the science by bringing together the world's leading experts in physical, chemical, and biological oceanography, marine geology, geochemistry, paleoceanography, and climate modeling. A mix of overview and research papers makes this volume suitable not only for experts in the field, but also for students and anyone interested in climate change and the oceans.

The Great Ocean Conveyor by Wallace Broecker Pdf

Exploring the link between the ocean's currents and rapid climate change Wally Broecker is one of the world's leading authorities on abrupt global climate change. More than two decades ago, he discovered the link between ocean circulation and climate change, in particular how shutdowns of the Great Ocean Conveyor—the vast network of currents that circulate water, heat, and nutrients around the globe—triggered past ice ages. Today, he is among the researchers exploring how our planet's climate system can abruptly "flip-flop" from one state to another, and who are weighing the implications for the future. In The Great Ocean Conveyor, Broecker introduces readers to the science of abrupt climate change while providing a vivid, firsthand account of the field's history and development. Could global warming cause the conveyor to shut down again, prompting another flip-flop in climate? What were the repercussions of past climate shifts? How do we know such shifts occurred? Broecker shows how Earth scientists study ancient ice cores and marine sediments to probe Earth's distant past, and how they blend scientific detective work with the latest technological advances to try to predict the future. He traces how the science has evolved over the years, from the blind alleys and wrong turns to the controversies and breathtaking discoveries. Broecker describes the men and women behind the science, and reveals how his own thinking about abrupt climate change has itself flip-flopped as new evidence has emerged. Rich with personal stories and insights, The Great Ocean Conveyor opens a tantalizing window onto how Earth science is practiced.
