Book excerpt: Formation of cold, dense waters south of the Antarctic Circumpolar Current (ACC) is one of the main drivers of the global overturning circulation, with major implications on the earth's climate. A key region where the densest waters on earth are formed is the Ross Sea which is separated from the ACC by the Ross Gyre. The strength and variability of the Ross Gyre circulation impact the formation and export of dense water, and it is therefore important to understand its circulation and dynamics. Observations in the Ross Gyre are limited because of its remote location and the severe weather conditions. Furthermore, the ice cover limits the application of remote sensing techniques. Quantitative estimates of the gyre's strength are difficult to obtain from hydrographic observations alone due to the limited sampling and the relatively weak stratification. In this dissertation, we use a combination of observations and modeling studies to a) provide an estimate of the strength and variability of the Ross Gyre transport and b) investigate the relative contributions of the wind and buoyancy forcing, eddies, and the presence of ACC to the Ross Gyre circulation. We find that the mean transport of the Ross Gyre can be as high as ~45 Sv, about twice of the typical estimate ~20 Sv reported in the literature. Sensitivity experiments to wind and buoyancy forcing, nonlinear terms, and the ACC were performed with a regional configuration of the Hybrid Coordinate Ocean Model (HYCOM). The numerical experiments show that the Ross Gyre, and its variability, are primarily wind-driven. The ACC is responsible for part of the recirculation. Buoyancy and nonlinearity/eddy do not appear to play a major role in the gyre dynamics.

Download or read book Ocean Dynamics and the Carbon Cycle written by Richard G. Williams and published by Cambridge University Press. This book was released on 2011-07-14 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook for advanced undergraduate and graduate students presents a multidisciplinary approach to understanding ocean circulation and how it drives and controls marine biogeochemistry and biological productivity at a global scale. Background chapters on ocean physics, chemistry and biology provide students with the tools to examine the range of large-scale physical and dynamic phenomena that control the ocean carbon cycle and its interaction with the atmosphere. Throughout the text observational data is integrated with basic physical theory to address cutting-edge research questions in ocean biogeochemistry. Simple theoretical models, data plots and schematic illustrations summarise key results and connect the physical theory to real observations. Advanced mathematics is provided in boxes and appendices where it can be drawn on to assist with the worked examples and homework exercises available online. Further reading lists for each chapter and a comprehensive glossary provide students and instructors with a complete learning package.
Download or read book Oceanography of the Ross Sea Antarctica written by Giancarlo Spezie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The era of the exploration of the World Ocean is not yet over: some areas still lack an adequate number of observations. The relationships between the physical, chemical and biological processes, which sustain the life on this planet, are not yet fully understood. In short, knowledge of the oceans is still far from satisfactory. This book covers an important period in the study of one of the last investigated areas of the World Ocean: the Ross Sea, Antarctica. During the 1990s, long-term experiments were conducted in this area as part of the Climatic Long-term Interaction for the Mass balance in Antarctica (CLIMA) project of the Italian National Programme for Antarctic Research (PNRA), providing a wealth of oceanographic information. This book is an outcome of the CLIMA field obser vations and international collaborations with the most important programmes in the Ross Sea-Southern Ocean area. It contributes to the st!ldies of the spatial and temporal variability of Ross Sea water masses and circulation and their relation ship with the Southern Ocean circulation. A comprehensive review of historical data is offered, and new data sets are analysed. The studies presented in this book show that much progress has been achieved during the last decade, but large gaps in our understanding of the physical processes in the Ross Sea are still to be filled. However, these studies contribute significantly to the investigation of some specific aspects regarding the circula tion of the main water masses.
Download or read book Aquatic Physiosphere Biosphere Dynamics and Modelling written by Aike Beckmann and published by Springer Nature. This book was released on 2021-02-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedia is a reference for aquatic physical, biological and biogeochemical sciences, collecting and connecting a number of topics, concepts and facts about aquatic systems and their scientific investigation. The scope of the book comprises the aquatic physiosphere-biosphere transition zone, an entity that encompasses both inanimate matter and collectives (the physiosphere) as well as living organisms and collectives (the biosphere). This combined approach is meaningful because both realms are intimately linked and because available methods of investigation are often similar. Much can be gained from considering both spheres at and across their interface jointly, and while there is a strong focus on marine systems, most concepts presented are also applicable to freshwater systems. This presented snapshot of knowledge of the transition zone between the aquatic physiosphere and biosphere is taken from a very specific angle: the point of view of a modeler. Modeling is not only a state-of-the-art mode of scientific investigation, but also requires the explicit specification of all assumptions (helping to avoid fallacies), and offers the advantage of being quantitative and allows for theoretical "what if" scenarios. As in any reference work, equal emphasis is given to fundamental facts, the definition of terms and the explanation of concepts, in an attempt to establish a joint language for physicists, biologists and biogeochemists. Although originating from a modeler's approach to nature, the resulting suite of compatible concepts may also be useful beyond modeling purposes. Furthermore, the material is presented in a condensed, straightforward way. Hence, the length of each entry is limited to one (occasionally two) pages, thus offering a quick introductory overview. This excludes lengthy derivations and very specialized details. The book is geared towards researchers, teachers and advanced students in the field of aquatic (marine and limnic) sciences, in particular those interested or involved in interdisciplinary work.
