The book is an up-to-date basic reference for natural gas hydrate (NGH) in the Arctic Ocean. Geographical, geological, environmental, energy, new technology, and regulatory matters are discussed. The book should be of interest to general readers and scientists and students as well as industry and government agencies concerned with energy and ocean management.
NGH is a solid crystalline material that compresses gas by about a factor of about 164 during crystallization from natural gas (mainly methane) - rich pore waters over time. NGH displaces water and may form large concentrations in sediment pore space. Its formation introduces changes in the geotechnical character of host sediment that allows it to be distinguished by seismic and electric exploration methods. The chemical reaction that forms NGH from gas and water molecules is highly reversible, which allows controlled conversion of the NGH to its constituent gas and water. This can be achieved rapidly by one of a number of processes including heating, depressurization, inhibitor injection, dissolution, and molecular replacement. The produced gas has the potential to make NGH a valuable unconventional natural gas resource, and perhaps the largest on earth.
Estimates for NGH distribution, concentration, economic targets, and volumes in the Arctic Ocean have been carried out by restricting the economic target to deepwater turbidite sands, which are also sediment hosts for more deeply buried conventional hydrocarbon deposits. Resource base estimates are based on NGH petroleum system analysis approach using industry-standard parameters along with analogs from three relatively well known examples (Nankai-Japan, Gulf of Mexico-United States, and Arctic permafrost hydrate). Drilling data has substantiated new geotechnical-level seismic analysis techniques for estimating not just the presence of NGH but prospect volumes.
In addition to a volumetric estimate for NGH having economic potential, a sedimentary depositional model is proposed to aid exploration in the five different regions around the deep central Arctic Ocean basin. Related topics are also discussed. Transport and logistics for NGH may also be applicable for stranded conventional gas and oil deposits. Arising from a discussion of new technology and methodologies that could be applied to developing NGH, suggestions are made for the lowering of exploration and capital expenses that could make NGH competitive on a produced cost basis.
The basis for the extraordinarily low environmental risk for exploration and production of NGH is discussed, especially with respect to the environmentally fragile Arctic region. It is suggested that because of the low environmental risk, special regulations could be written that would provide a framework for very low cost and safe development.

Описание: Eurasian Crossroads is the first comprehensive history of Xinjiang, the vast central Eurasian region bordering India, Pakistan, Afghanistan, Tajikistan, Kyrgyzstan, Kazakhstan, Russia, and Mongolia. Forming one-sixth of the People`s Republic of China (PRC), Xinjiang stands at the crossroads between China, India, the Mediterranean, and Russia and has, since the Bronze Age, played a pivotal role in the social, cultural, and political development of Asia and the world. Xinjiang was once the hub of the Silk Road and the conduit through which Buddhism, Christianity, and Islam entered China. It was also the site where Chinese, Turkic, Tibetan, and Mongolian empires communicated and struggled with one another. Xinjiang`s population comprises Kazakhs, Kirghiz, and Uighurs, all Turkic Muslim peoples, as well as Han Chinese, and competing Chinese and Turkic nationalist visions continue to threaten the region`s political and economic stability. Drawing on primary sources in several Asian and European languages, James Millward studies Xinjiang`s history and people from antiquity to the present and takes a balanced look at the position of Turkic Muslims within the PRC today.

Описание: This book provides a comprehensive review of the biogeochemistry in the Baltic Sea. It is based on the fact that biogeochemical processes that are relevant for the ecological state of the Baltic Sea (and other sea areas), are all in some way related to the production and mineralization of organic matter (biomass) and thus are associated with the consumption or release of CO2. The significant progress with regard to our chemical analytical capabilities concerning the marine CO2 system has facilitated new approaches to study the Baltic Sea biogeochemistry, in particular with regard to a quantitative process understanding. To demonstrate this, the authors present the fundamentals of the marine CO2 system in a theoretically sound, but still intelligible way. This is followed by a comprehensive presentation of our current knowledge about the CO2 system in the Baltic Sea and the implications for our understanding of biogeochemical processes such as production/mineralization of organic matter and the stoichiometry involved, nitrogen fixation, denitrification, and phosphate transformations at varying redox conditions. Finally, the CO2 gas exchange balance and related problems such as acidification are addressed.

Описание: This book discusses the water and carbon cycle system in the permafrost region of eastern Siberia, Providing vitalin sights into how climate change has affected the permafrost environment in recent decades. It analyzes the relationships between precipitation and evapotranspiration, gross primary production and runoff in the permafrost regions, which differ from those intropical and temperate forests. Eastern Siberia is located in the easternmost part of the Eurasian continent, and the land surface with underlying permafrost has developed over a period of seventy thousand years. The permafrost ecosystem has specific hydrological and meteorological characteristics in terms of the water and carbon dynamics, and the current global warming and resulting changes in the permafrost environment are serious issues in the high-latitude regions. The book is a valuable resource for students, researchers and professionals interested in forest meteorology and hydrology, forest ecology, and boreal vegetation, as well as the impact of climate change and water-carbon cycles in permafrost and non-permafrost regions.
Much attention has been given to above ground biomass and its potential as a carbon sink, but in a mature forest ecosystem 40 to 60 percent of the stored carbon is below ground. As increasing numbers of forests are managed in a wide diversity of climates and soils, the importance of forest soils as a potential carbon sink grows.
The Potential of U.S. Forest Soils to Sequester Carbon and Mitigate the Greenhouse Effect provides researchers and policy makers with an understanding of soil processes and their relation to carbon dynamics, as well as strategies to monitor and techniques to measure forest soil carbon. It covers the effects of management on soils in a wide range of forest ecosystems together with policy options that are effective and benefit both the forest community and the over all environment. This valuable reference provides forest managers, urban planners, land owners, policy makers, and the general public with guidance that will allow for a holistic approach to land management, environmental quality, and improved forest productivity.
