Book excerpt: The Indian Ocean and its Role in the Global Climate System provides an overview of our contemporary understanding of the Indian Ocean (geology, atmosphere, ocean, hydrology, biogeochemistry) and its role in the climate system. It describes the monsoon systems, Indian Ocean circulation and connections with other ocean basins. Climatic phenomena in the Indian Ocean are detailed across a range of timescales (seasonal, interannual to multi-decadal). Biogeochemical and ecosystem variability is also described. The book will provide a summary of different tools (e.g., observations, modeling, paleoclimate records) that are used for understanding Indian Ocean variability and trends. Recent trends and future projections of the Indian Ocean, including warming, extreme events, ocean acidification and deoxygenation will be detailed. The Indian Ocean is unique and different from other tropical ocean basins due to its geography. It is traditionally under-observed and understudied, yet plays a fundamental role for regional and global climate. The vagaries of the Asian monsoon affect over a billion people and a third of the global population live in the vicinity of the Indian Ocean. It is also particularly vulnerable to climate change, with robust warming and trends in heat and freshwater observed in recent decades. Advances have recently been made in our understanding of the Indian Ocean’s circulation, interactions with adjacent ocean basins, and its role in regional and global climate. Nonetheless, significant gaps remain in understanding, observing, modeling, and predicting Indian Ocean variability and change across a range of timescales. As such, this book is the perfect compendium to any researcher, student, teacher/lecturer in the fields of oceanography, atmospheric science, paleoclimate, environmental science, meteorology and geology, as well as policy managers and water resource managers. Provides interdisciplinary content with a comprehensive overview for students and practitioners from a wide range of disciplines as well as for stakeholders Presents a broad overview and background on the current state of knowledge of the variability, change, and regional impacts of the Indian Ocean Includes links to animations, slideshows, and other educational resources

Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 185. Indian Ocean Biogeochemical Processes and Ecological Variability provides a synthesis of current knowledge on Indian Ocean biogeochemistry and ecology and an introduction to new concepts and topical paradigm challenges. It also reports on the development of more extensive/frequent observational capacity being deployed in the Indian Ocean. This represents the first collection of syntheses that emphasize a basin-wide perspective, and the contributing authors include some of the most esteemed oceanographers and Indian Ocean experts in the world. The volume is derived from invited plenary talks that were presented at the initial Sustained Indian Ocean Biogeochemistry and Ecosystem Research (SIBER) workshop held at the National Institute of Oceanography (NIO) in Goa, India, in October 2006. The volume discusses The overlying physical processes set by monsoonal forcing and how these control biological production and variability Nutrient cycling and limitation Pelagic carbon cycling and air-sea exchange Benthic biogeochemistry and ecology The impact of climate and human activities on biogeochemistry and ecosystems. The readership for this book will consist of academic and governmental researchers interested in exploring how oceanographic, atmospheric, and hydrological processes combine to establish the environmental setting that supports and drives the pelagic system and which are especially relevant to understanding the complex biogeochemical and ecological interactions in the Indian Ocean.

This book was released on 2016 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large-scale climate system is driven by imbalances of the reservoirs of heat contained in the world oceans. The transport and redistribution of this heat is determined in part by nonlinear mesoscale eddies (radii ~50-200 km), as well as by planetary waves whose widths approach the size of mesoscale eddies away from the equator. In this dissertation, new analysis techniques are developed and implemented to assess oceanic phenomena in two regions: mesoscale eddy-mean flow interaction in the Kuroshio Extension (KE) region, and the effects of coastal Kelvin waves and mesoscale eddies in the Indian Ocean south of Java. In the KE region, a jet-following coordinate reference frame is used to quantify the contributions of eddies to the vorticity budget along the KE jet in a strongly eddying ocean general circulation model simulation, the Parallel Ocean Program (POP). The jet reference frame preserves synoptic gradients of the jet that are not accurately represented in multi-year Eulerian means. This analysis found that eddies tend to accelerate the jet just downstream of crests in the topographically-induced meanders, implying an intensification of frontal gradients in these areas. In the Indian Ocean, a method involving projections of harmonic basis functions onto altimetry-derived sea level anomaly (SLA) is used to estimate Kelvin wave activity along the equatorial-coastal waveguide. The resulting Kelvin wave coefficient presents a more accurate representation of Kelvin wave activity than that from raw SLA. Moreover, values of the Kelvin wave coefficient in April-June are a robust predictor of positive Indian Ocean Dipole (pIOD) event development later in the calendar year. Finally, a temperature budget using a strongly eddying POP simulation isolates the specific contributions of mesoscale processes south of Java. It shows that Kelvin waves and local wind forcing both contribute substantially to anomalous cooling during pIOD years, while mesoscale eddies have a modest warming effect. These results suggest that mesoscale processes in the study regions have an important influence on the ocean's structure and can trigger a climate response; use of the new analysis techniques may help quantify the effects of mesoscale eddies and planetary waves elsewhere in the oceans.

Book excerpt: The Indian Ocean region is a large maritime-littoral space of geo-political, geo-economic and geo-strategic significance. It is characterized by globalization, maritime trade, extra regional naval presence, asymmetric actors and non-traditional security challenges arising from climate change and natural disasters. Significantly, economics and security has been the significant feature of transactions that have shaped the historical and contemporary discourse in the region. In its historical geo-economic construct, the Indian Ocean facilitated links among the ancient trading systems of the Mediterranean, Arabian Peninsula and the Asia. There is a strong element of continuity and in the 21st century trade and energy flows link the Indian Ocean region to the global economies of the Asia–Pacific, Europe and North and South America. In its geo-strategic construct the Indian Ocean region has been an arena for rivalry between the great powers and in contemporary times the region continues to be of strategic significance to the United States, European powers, China, India and Japan whose forces are forward deployed in support of strategic and economic interests. At the functional–operational level, several extra regional navies are deployed in the Indian Ocean in support of the war on terror and to counter piracy off Somalia. In essence, the Indian Ocean region emerges as an arena of competition and cooperation and it is in this context that this paper attempts to examine its strategic dynamics. It begins by mapping the Indian Ocean and highlights the significant physical characteristics of this body of water which shape the geo-political, geo-economic and geo-strategic discourse followed by a brief historical narrative that showcases the continuity in the importance of the Indian Ocean from ancient times into the 21st century. Given these realities, it is argued that extra regional powers have exhibited a strong penchant to steer the political–economic–strategic dynamics of the Indian Ocean. Despite the apprehension of regional countries of this extra regional reality, some have been supportive of their presence. At another level, the non-traditional threats and challenges confronted by the Indian Ocean littorals are examined and proposals offered for maritime multilateralism to be a tool for states to develop cooperative mechanism for building mutual trust and confidence.

Book excerpt: One of the major experiments in earth science at the present time is about to begin: the World Climate Research Program (WCRP). The objectives of WCRP are to determine the extent to which climate change can be predicted, and the extent to which human activities (such as increasing the level of CO ) can influence our climate. 2 To understand and possibly to predict climate change, one needs a good understanding of the dynamics of the ocean, the atmosphere, and the processes by which they are coupled. Two major programs are being developed within WCRP: TOGA (Tropical Oceans, Global Atmosphere) and WOCE (World Ocean CirculatIon Experiment). The success of these programs will depend on many things, not least of which is the existence of a pool of active young researchers. This NATO Advanced Study Institute brought together students and young scientists from 13 countries, most of them from Europe and North America. The objective was to provide them with a background in the perceived state of knowledge of atmosphere and ocean dynamics, and to mediate a flavour of the problems presently concerning scientists active in climate related dynamics. In the past, the two disciplines of oceanography and meteorology have largely been carried out separately. But for climate research both disciplines must interact strongly, and another ob jecti ve of this school was to bring together both oceanographers and meteorologists. To promote an integrated approach, the lecture presentations were divided into two formats.

Available in PDF, EPUB and Kindle. Book excerpt: The Indian Ocean represents a part of the global Ocean that has been less studied by modern oceanography than the Atlantic and Pacific parts. This is remarkable, since the Indian Ocean was subject to much historic exploration through navigators from Asia, India, the Middle East and lastly from Europe. This unique, comprehensive reference set on the Indian Ocean, covers all oceanographical aspects with its physics, chemistry, biology and geology in 21 peer-reviewed expert-written chapters. Besides the well-ground basis on the Ocean’s characteristics and a wealth of data, some unique features presented are the monsoon - the biennial reversal of winds and the resultant surface circulation; the tropical and sub-tropical jet streams, namely the Somali current, the Agulhas current and the Leevwin current; the oxygen-poor intermediate waters in its northern part which significantly contribute several green house gases to the atmosphere, for example, carbon dioxide, nitrous oxide, methane and dimethyl sulphide; its exhaustive coral reefs and mangrove vegetation; and the polymetallic nodules at its depths and its other mineral resources. Moreover, an analysis is provided of the anthropogenic contributions and their impacts on the health of the Indian Ocean; and that of estuary environments of important rivers of the 15 littoral countries. Intended for research scientists, professionals and students working in physical, chemical and geological oceanography.
