Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 184. Carbon Cycling in Northern Peatlands examines the role that northern peatlands play in regulating the atmospheric carbon budget. It summarizes current research in four interconnected areas: large-scale peatland dynamics and carbon cycling; plant and microbial dynamics and their effect on carbon fluxes to the atmosphere; methane accumulation in, and loss from, peatlands; and water and dissolved carbon fluxes through peatlands. The volume highlights include A thorough assessment of the challenges involved in incorporating carbon cycling in northern peatlands into global climate models; A conceptual model to examine the partitioning of terminal carbon mineralization into production of CO2 and CH4; A comprehensive review of the evidence for the accumulation of methane in deep and shallow peat; and A description of the hydrologic changes induced by peat harvesting and associated challenges in restoring altered peatlands to their natural hydrologic regime. Carbon Cycling in Northern Peatlands will be of interest to research scientists and graduate and undergraduate students, particularly those who wish to know more about the role of peatlands in the global carbon cycle and their role as modifiers of climate.

Download or read book Autogenic and Allogenic Controls on Carbon Dynamics in Peatlands from Alaska and Patagonia written by Julie Loisel and published by . This book was released on 2012 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In peatlands, both internal dynamics and external forcing drive changes in hydrological conditions and vegetation communities, which affect short- and long-term peat accumulation processes and associated carbon sequestration. Understanding the spatial and temporal dynamics of these autogenic and allogenic controls is of critical importance for documenting peatland development and assessing the peatland carbon-sink function, especially because climatically-induced changes in peatland hydrology and vegetation are likely to have considerable effects on peat-carbon fluxes. In my dissertation, I present a range of evidence from Alaska and Patagonia demonstrating that peatland-carbon dynamics are controlled by hierarchical interactions between regional climate dynamics, landscape morphology, and spatially-explicit local community structures.

Download or read book Mesoscale Wind and Temperature Changes Over Peatlands of the Hudson Bay Lowlands written by Olalekan Oluleye Balogun and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although northern peatlands in general are currently a net carbon sink, there is still considerable uncertainty in the long-term combined response of plant productivity and ecosystem respiration to global warming and moisture changes. The Hudson Bay Lowlands (HBL) region of Canada is the second largest peat-accumulating complex in the world that is strongly influenced by the cold air masses originating off the Hudson Bay. Recent warming has caused observed changes in the sea ice dynamics and energy budget of the Hudson Bay, yet it is presently unknown how these climatic changes in the Bay will impact the surface energy and carbon balance of the adjacent HBL. As a globally significant peatland carbon pool, the HBL will play an important role in future climate warming and permafrost carbon feedback. The primary aim of this study is to improve our understanding of the warming-induced changes in the advective influence of the Hudson Bay and its linkage to the changes in the surface energy and carbon balance over peatlands of the HBL. I use a combined model and assimilated climate dataset to investigate the mesoscale wind and temperature changes in the HBL and their impacts on the surface energy balance (1979-2018). Furthermore, I employ a satellite data-driven light-use efficiency model, calibrated and validated with eddy covariance tower measurements at a fen and bog to examine the response of net ecosystem CO2 exchange to climatic changes (2000-2019). The results reveal that differential rates of warming between offshore and onshore winds have produced significant changes in the advective role of the Hudson Bay as evident in the increased frequency and strength of onshore winds. Also, the results show contrasting net CO2 exchange between the fen and bog sites. The anomalies in gross primary production and ecosystem respiration were associated with strong trends in temperature and moisture, and the Hudson Bay had a more pronounced advective influence on peatland respiration than photosynthesis.

Download or read book Wetland Carbon and Environmental Management written by Ken W. Krauss and published by John Wiley & Sons. This book was released on 2021-11-23 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
Download or read book Tropical Peatland Ecosystems written by Mitsuru Osaki and published by Springer. This book was released on 2015-12-07 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.

Download or read book The Quaternary Period in the United States written by A.R. Gillespie and published by Elsevier. This book was released on 2003-12-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.
Download or read book The Carbon Cycle written by T. M. L. Wigley and published by Cambridge University Press. This book was released on 2005-08-22 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing carbon dioxide (CO2) emissions is imperative to stabilizing our future climate. Our ability to reduce these emissions combined with an understanding of how much fossil-fuel-derived CO2 the oceans and plants can absorb is central to mitigating climate change. In The Carbon Cycle, leading scientists examine how atmospheric carbon dioxide concentrations have changed in the past and how this may affect the concentrations in the future. They look at the carbon budget and the "missing sink" for carbon dioxide. They offer approaches to modeling the carbon cycle, providing mathematical tools for predicting future levels of carbon dioxide. This comprehensive text incorporates findings from the recent IPCC reports. New insights, and a convergence of ideas and views across several disciplines make this book an important contribution to the global change literature.
