Discover Gt Aide (Global), the freeware that makes learning and exploring Earth science as easy as playing a game through this book. The freeware is designed for students and researchers and offers six powerful modules to guide them through coordinates, gridding, sampling, and more, all without the need of any formal GIS training. Visualize data on Google Earth, master essential geospatial skills, and unlock the potential of geology with Gt Aide. Each module is coded in such way that makes the procedure simple but substantially useful. At the same time, this book is an introduction to the freeware with several tasks in each chapter that are meticulously carved out to make students ponder ideas and instil confidence. Once you start browsing the book and handling the freeware you will realize Gt Aide (Global) is indeed a treatise in Field Planning.
This edited volume dedicated to late Prof. P.S. Saklani addresses the multidisciplinary themes pertaining to role of tectonism and magmatism in Crustal Evolution and global distribution of metallic and non metallic mineral deposits. It gives valuable information on geodynamic evolution, structural, petrological, isotopic, metamorphic, geochemical and geochronological attributes of continental and oceanic crust and is challenging reassessments of the existing paradigms. It addresses the implication of magmatism, metallogeny and application of geochronological ages (U-Pb SHRIMP age, Lu-Hf isotopic system; detrital zircons). This book also advocates the role of tectonics in contamination of ground water, and control on drainage pattern and geothermal systems. It explores the vulnerability of earth towards natural hazards viz. earthquakes, floods, cyclones, tsunami, volcanism, cyclones and drought. This volume throws light on the applications of remote sensing, GIS (Geographical Information System) and SRTM data for evaluation of the morphometric and morphotectonic parameters and exploring the susceptibility of river basins toward erosion and flood. It will be beneficial to graduate and post-graduate students as well as professionals and researchers.
This book provides a comprehensive overview of recent research on estuaries of the east coast of India, and how changing biogeochemical dynamics as a result of climate change and human activity have impacted estuaries and other open water ecosystems. Though estuaries only cover a very small portion of the earth’s hydrosphere, they are some of the most biogeochemically active regions among the global water bodies. As such, this book focuses on estuaries of the east coast of India going all the way to the Bay of Bengal, which is the world's largest freshwater input from perennial rivers and rain-fed estuaries, and is therefore a unique area of study. Through its unique coverage of the Bay of Bengal in particular, the book presents a new perspective not present in the literature on estuary biogeochemistry and ecosystem dynamics. Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life below Water), with a focus on ecosystem services of the natural aquatic system.The book will be useful to researchers, policy makers, coastal managers and marine sustainability scientists and organizations.
This handbook summarizes the main advances in our understanding of marine minerals and concentrates on the deposits of proven economic potential. In cases where our knowledge may be too limited to allow defining of their economic potential, those minerals are covered regionally or by deposit type. Handbook of Marine Mineral Deposits is divided into three sections; Marine placers, manganese nodules and crusts, and deep-sea hydrothermal mineralization. All of these mineral deposits have great potential importance to economic geologists and marine mines. Edited by an acknowledged expert in the field, this handbook includes work by internationally renowned contributors. The new United Nations Law of the Sea, ratified by over 100 countries within the past two years, provides a framework and guidelines for deep-sea mineral exploration that increases international interest in this book. The Handbook serves as a platform from which to launch the more detailed evaluation studies that will need to take place in the 21st century before recovery can continue or commence. Handbook of Marine Mineral Deposits is useful to mineralogists, economic geologists, marine geologists, marine miners, and conservationists. Features
Dans un passé assez récent, un intérêt sans précédent s'est développé concernant les ressources globales. Nous nous rendons maintenant compte que les ressources biologiques sont loin d'être illimitées et pendant les dernières décennies du 20ème siècle, des efforts ont débuté pour contrôler nos usages de l'environnement et qui agissent les uns avec les autres dans les écosystèmes dont nous dépendons finalement. Le projet "Mers au millénaire": Une Evatuation Environmentale sur la zone côtière couvre le secteur où vit plus d'un quart de l'humanité, et jusque au bas du plateau continental. Ces trois livres se concentrent sur la biosphère où les interactions de l'homme avec les mers et leurs systèmes biologiques et physiques sont le plus sensibles. 135 chapitres écrits par les experts internationaux et les scientifiques travaillant dans ce domaine offrent un sommaire unique des mers et des océans du monde. À la fin du millénaire les auteurs à travers le monde ont examiné l'état de nos habitats marins et côtiers. Pour la première fois, ils ont uni leurs efforts de par le monde pour s'assurer que ces habitats restent dans un état de fonctionnement durable et stable; l'information a été documentée et assemblée dans une source bibliographique unique. "Mers au millénaire" fournit aux scientifiques dans le monde entier une occasion unique pour s'enrichir de toutes ces expériences. Les trois volumes de "Mers au millénaire" couvrent des chapîtres d'importance globale et régionale comme : description biologique des eaux côtières et du plateau continental; développement et utilisation de la zone côtière; effets des dragages et autres techniques d'accrétion sédimentaire; effet dans le temps des déversement de polluants;de pêche; méthodes et techniques de gestion utilisées pour gérer en continu les écosystèmes. Plus de 800 figures comprenant des cartes, les graphiques, les dessins au trait et les photograph.
