Permafrost : distribution, composition and impacts on infrastructure and ecosystems( )

10 editions published between 2013 and 2014 in English and held by 678 WorldCat member libraries worldwide

This book is in response to the growing demand from academics and the general public for state-of-the-art research in permafrost science and, in particular, information about its impacts on infrastructure and ecosystems. It brings together research from diverse but highly complementary scientific disciplines to illuminate the main physical, chemical and biological processes occurring in permafrost systems and identifies the possible mechanisms controlling fluxes of energy and matter at various scales. Taken together, the 8 chapters of this book provide a comprehensive, up-to-date description and analysis of the basic geomorphological, physical, hydrological, chemical and biological aspects of permafrost-affected ecosystems, their interaction with other components of the landscape and their impact on human life and infrastructure

The Arctic: : current issues and challenges by Oleg S Pokrovsky( )

5 editions published in 2020 in English and Undetermined and held by 650 WorldCat member libraries worldwide

"The importance of the Arctic in many fields of human activity strongly increased over the past decades. The academic scientific research demonstrates a 3-fold increase in the number of journal articles dealing with "Arctic": from 1,400 in 2000 to 4,200 in 2018. This increase is not fortuitous but certainly stems from double importance of Arctic regions for humanity. The first importance is the role that the Arctic plays in the on-going environmental changes, mostly linked to climate warming and environmental pollution. Here, the first key issues are the Arctic Ocean, ice melt, permafrost thaw, greenhouse gases emission, and organic carbon mobilization from soils to rivers. From the other hand, highly fragile Arctic ecosystems and biota are strongly affected by environmental pollution, be it organic compounds or toxic metals and radionuclides. The rising concern of humanity to the key role of the Arctic in climate regulation on the planetary scale and the extreme fragility of its ecosystem, biota and native population to on-going environmental change can certainly explain an explosive interest of scientific researchers to the Arctic in connection with 'climate change'. The second big issue of the Arctic is its eminent role in problems of natural resources. The Artic shelf contains vast amount of hydrocarbons (gas and oil), whereas the terrestrial polar regions, now liberating from ice, may turn out to be highly important sites of future ore industry. The importance of possibly ice-free Arctic Ocean as future maritime shipping routes will further enhance the accessibility of natural resources in this region. Taken together, this can be the main driving factors of almost exponential increase in the interest to natural resources in the Arctic over past few years. The present book addresses a wide variety of environmental, social and economic issues of the Arctic, in response to rising interest to this region in academic science, sociology and business. The 14 chapters represent state-of-the art reviews written by the experts on problems of native communities, climate change, political issues, implementation of large-scale projects, natural resources and conservation, environmental monitoring and assessment of pollution issues"--

LAKE WATER : properties and uses case studies of hydrochemistry and hydrobiology of lakes in... northwest russia by Oleg S Pokrovsky( )

3 editions published between 2020 and 2021 in English and held by 10 WorldCat member libraries worldwide

"Lake ecosystems are known to be valid sentinels for current climate changes and anthropogenic pressure because they provide indicators of these impacts either directly or indirectly through the influence of climate and human activity on their catchments. Among these indicators, to name just a few, are water temperature, dissolved organic carbon, nutrients and metals, phyto- and zooplankton composition as well as population and biodiversity of crustacea, mollusks and fish. The advantages of using lakes as tracers of climatic changes and anthropogenic impacts on aquatic ecosystems are multiple. Lake ecosystems are well constrained, confined and are studied in a sustained fashion; lakes respond directly to climate change and local and global pollution via incorporating the effects of these impacts occurring within the catchment; lakes integrate responses over time, and thus allow to avoid the random or unique single-time effects. Finally, lakes of various sizes are distributed worldwide and, as such, can act as sentinels across various climatic conditions while exhibiting different degrees of vulnerability to external pressure depending on their size and specific location capturing different aspects of climate change (e.g., changing precipitation regime, heat waves, permafrost thaw, invasion of new species, local and global (dispersed) pollution). However, the majority of published studies on lakes in the boreal and subarctic zone deal with Western and Northern Europe and Northern America, with quite limited information on lakes in the NW Russia. This book is intended to partially fill this gap by presenting 13 chapters describing the hydrology, hydrochemistry and hydrobiology of various lakes located in the NW European Russia, from the Finland border in the West to the Ural Mountains in the East. The thirteen chapters of the book, written by the experts in the field of biogeochemistry, limnology and zoology cover full limnetic ecosystems, from lake physical characteristics to lake water chemistry, microbiology, phytoplankton and zooplankton population, Crustacea, mollusks and fish. A multidisciplinary approach across wide geographical zones, comprising both small and large lakes of the Russian Subarctic, presented in this book, will be interesting for a large community of scholars, students, and researchers from academic and private organizations"--

Particularités biogéochimiques et hydrochimiques des lacs thermokarstiques de l'ouest de la Sibérie : le rôle de leurs macrophytes by Rinat Manasypov( Book )

3 editions published between 2013 and 2017 in English and held by 3 WorldCat member libraries worldwide

New data on biogeochemical cycles of chemical elements inside thermokarst ecosystems in the north of West Siberia was received. The concentrations of chemical elements in macrophytes, bed deposits, interstitial and lake waters of thermokarst lakes were studied. The peculiarities of lake water chemical structure on different stages of thermokarst ecosystems development in the north of West Siberia were revealed. Lateral characteristics of the chemical structure of West Siberian thermokarst lakes situated in 900 km zone of continuous permafrost were studies for the first time. This has made possible to predict the changes in the concentration of organic carbon, macro- and microelements dissoluted in case the climate changes
Cycle biogéochimique du silicium dans les environnements superficiels continentaux : impact des plantes terrestres by Fabrice Fraysse( Book )

2 editions published between 2007 and 2010 in French and held by 3 WorldCat member libraries worldwide

The aim of this experimental study is, in a first time, the characterization of reactivity and physico-chemical properties of micrometrics biogenic opals called phytoliths for several terrestrial plants species from differents environments. In this regard, several complementary technics were used, such as solubility measurements, dissolution kinetics, electrophoretic measurements and potentiometric titrations, that allowed better constraining the acid-base surface reactions and thermodynamic and kinetic parameters of phytoliths interactions with aqueous solutions. In the second part of this work, we studied terrestrial plant litter interaction with aqueous solutions via litter degradation experiments in batch and mixed-flow reactors. Obtained results demonstrated high aqueous reactivity of both phytoliths and plant litter that exceeds dissolution rate of common soil minerals by 1-2 orders of magnitude. Quantitative evaluation of plant litter and phytoliths control on Si release from these solid reservoirs demonstrates strong possible impact of plants on biogeochemical cycle of silicon in almost all terrestrial environments

Biogeochemistry of thermokarst lakes of western Siberia by Oleg S Pokrovsky( )

1 edition published in 2014 in English and held by 2 WorldCat member libraries worldwide

Le site de l'éditeur indique : "This book described the current status and possible future changes of the thermokarst (thaw) lakes of western Siberia as dominant forms of landscape and regulators of greenhouse gas exchange within the atmosphere. Thawing permafrost and resulting microbial decomposition of previously frozen organic carbon is one of the most significant terrestrial ecosystem positive feedbacks to a warming climate. Ongoing processes of the permafrost thawing in Western Siberia are likely to increase the surface of water bodies via forming so-called thermokarst lakes, mobilizing the organic carbon (OC) from the soil pool to the rivers and, finally, to the ocean, and thus modifying the fluxes of methane (CH4) and CO2 to the atmosphere. Despite their tremendous importance for green house gazes regulation and hydrological regime control, very little is known about hydrochemistry of western Siberia thaw lakes. This book assesses the variation of major and trace elements (TE) and organic carbon (OC) concentration along the chronosequence of lake development and the latitude profile of variable permafrost abundance; characterizes the colloidal status of TE and distinguishes between the relative proportion of organic and organo-mineral colloids; describes the particularity of microbiological composition of thermokarst lake waters and production/mineralization processes in the water column; and presents the perspective of water chemical composition evolution under the climate change scenario. Each of these aforementioned objectives present a scientific challenge given mainly the paucity of existing information on these important but still very poorly studied ecosystems. Taken together, understanding of these issues and identification and quantification of controlling environmental parameters should produce conceptually new knowledge of biogeochemical processes operating within the Western Siberia Plain with the possibility of extrapolation of generated knowledge to much larger territories of arctic and subarctic permafrost-affected areas."
