Book Description
Intense uplift of the Tibetan Plateau in Late Cenozoic Era is one of the most important events in geological history of the Earth. The plateau offers an ideal region for studying of lithospheric formation and evolution, probing into the mechanism of crustal movement, and understanding of changes in environments and geo-ecosystems in Asia. Intense uplift ofthe plateau resulted in drastic changes of natural environment and apparent regional differentiation on the plateau proper and neighboring regions. The plateau therefore becomes a sensitive area of climate change in Asian monsoon region, which is closely related to the global change. As a special physical unit, its ecosystems occupy a prominent position in the world. Due to its extremely high elevation and great extent, natural types and characteristics of physical landscapes on the plateau are quite different from those in lowlands at comparable latitudes, and environments are also different from those in high latitudinal zones. Consequently, the Tibetan Plateau has been classified as one of three giant physical regions in China and considered as a unique unit on Earth. Scientific surveys and expeditions to the Tibetan Plateau on large scale began from 1950's. Amongst them, a number of comprehensive scientific expeditions to the Xizang (Tibet) Autonomous Region, Hengduan Mts. areas, Karakorum and Kunlun Mts. regions, as well as the Hoh Xii Mts. areas, have been successively carried out by the Integrated Scientific Expedition to Tibetan Plateau, sponsored by Chinese Academy of Sciences since 1973.

Book Description
Natural gas hydrate, a solid form of natural gas and water, occurs in nature in association with deep permafrost and in offshore environments adjacent to continental margins. This report presents results of a gas hydrate research well project located at the north-eastern edge of the Mackenzie Delta. The project brought together researchers from North America and Japan to undertake the first investigation of a natural gas hydrate occurrence beneath permafrost that included extensive dedicated coring and associated engineering and scientific studies. The report compiles papers from the project in the following categories: an overview of the project, including drilling operations; a regional overview of gas hydrate occurrences, permafrost conditions, and geology in the project area; geology and biostratigraphy of the drilled cores; physical properties and geochemistry of the cores; characteristics of the gas hydrate, including chemical and physical analyses; downhole geophysics; and regional gas hydrate occurrences, production, and climate change considerations. Includes author index.

Book Description
Studies of aeolian sediments, both ancient and modern, have exhibited a number of important conceptual advances in recent years. In particular, there has been a move away from descriptions of sediments, bedforms and sedimentary environments toward a new emphasis on the dynamics of aeolian depositional systems at different temporal and spatial scales, and their response to external changes in sea levels, regional and global climates and tectonics. This Special Publication contains a selection of papers that were presented at the Symposium "Aeolian Sediments: Ancient and Modern" held in 1990. It also includes a number of contributions from authors who were not able to attend the meeting, but whose work reflects important aspects of contemporary research in aeolian sedimentology. State-of-the-art research papers in aeolian sedimentology International, expert authorship Of relevance to modern concerns about global climate change If you are a member of the International Association of Sedimentologists, for purchasing details, please see: http://www.iasnet.org/publications/details.asp?code=SP16

Book Description
This is a timely, interdisciplinary scientific overview of the atmosphere, the ocean and the land surface as it interacts with physical, chemical and biological processes. The high level of detail sets it apart from other studies of monsoon meteorology. The text includes analysis of paleoclimate records, human influences on the monsoon climate and the economic impacts of the monsoon on economies and to human health.

Book Description
Asian river basins are undergoing rapid transformation. This volume considers the implications of the environmental change-development nexus for water management, river health and hazard awareness. As Biswas and Tortajada (2011) have recently commented, water management in Asia will likely change more in the next twenty years than in the last 2000 years. Critical environmental trends include decreasing flows of water and sediment due to dam construction and increased water extraction, land use change (especially forest removal), encroachment and degradation of floodplain and wetland environments, increased water demand and concerns about water security, urban expansion and associated pollution of rivers and contamination of groundwater reserves. These challenges are being reframed by new approaches to water management which represent a transition from engineering-dominated approaches towards integrated water management, from technology transfer to adaptive technologies. The volume comprises an introduction and five chapters. Brierley and Callum reframe approaches to river repair within emerging theories of in ecology and earth science which regard nature as a complex adaptive system replete with inherent uncertainties. These ideas are mirrored in the four case study chapters which deal with water governance in the Mekong Basin (Hirsch); hybrid adoption of water resource technologies in India (Barbanente et al.); determination of sediment dynamics in Java Rijsdijk); and ecological conservation imperatives in the headwaters of the Yellow, Yangtze and Mekong rivers in western China (Li et al.).
