Book Synopsis Annually Laminated Lake Sediments by : Wojciech Tylmann
Download or read book Annually Laminated Lake Sediments written by Wojciech Tylmann and published by MDPI. This book was released on 2020-04-28 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The collection of papers presented in this book illustrates the recent progress made in varved sediment research and highlights the large variety of methodological approaches and research directions applied. The contributions cover monitoring of modern sediment fluxes using sediment traps; geochronological and sedimentological analyses of annually laminated lacustrine sediments or varves; and multiproxy investigations, including geochemical and biological proxies as well as spatiotemporal analyses based on multicore studies supported by satellite images and X-ray computed tomography (CT). The scientific issues discuss the influences of hydrological and climatological phenomena on short-term changes in sediment flux, the relationships between biogeochemical (limnological) processes in the water column and the formation of varves, the preservation of environmental signals in varved sediments, and possibilities of synchronizing varved records with other high-resolution environmental archives such as tree rings.

This book was released on 2010-01-18 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2008 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1,0, University of Canterbury (Department of Geology), course: Paleoecology and Paleolimnology, language: English, abstract: Zolitschka (1998) defined varves as laminated sediments occurring in stationary water bodies. Their striking feature is a seasonal, rhythmical build-up of thin, horizontal layers with a changing composition. Since the early 20th century, this type of sediment has been used for establishing exact geochronologies. In the course of the climate change debate, and the subsequent demand for high-resolution paleoclimatic data, they have come back into the focus of earth scientists. A crucial advantage of varved sediments is that they provide two different kinds of information on a sediment profile: an absolute chronology and high-resolution paleoclimatic information. Combining these two attributes offers an absolute dated time series of paleoclimatic proxy-data. Furthermore, additional analyses of the same profile can be dated. Varved sediments can be found in recent lakes as well as in paleolakes. However, their occurrence is limited to only a few sites as a consequence of the special circumstances necessary for their generation. Varved sediments in recent lakes are especially found in lakes, which are small and deep. These preconditions are often met by maars, where a lot of investigations are done (Brauer et al. 1999a, 1999b; Litt et al. 2001). Additionally, varved sediments are even found in ancient proglacial lakes (Moscariello et al. 2000) to give an example.

Book Synopsis Palaeoclimatology and Palaeoceanography from Laminated Sediments by : Alan E. S. Kemp
Download or read book Palaeoclimatology and Palaeoceanography from Laminated Sediments written by Alan E. S. Kemp and published by Geological Society of London. This book was released on 1996 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnitude and causes of decadal to century-scale changes in climate are major issues of global concern. The separation of anthropogenically driven change from natural 'baseline' variability within the atmosphere/ocean system is a prerequisite to identifying human impact on global climate. An understanding of past climate variability is therefore a key to predicting future climate change. The sedimentary record of the oceans, seas and lakes is produced by a series of depositional events that occur on seasonal timescales but can rarely be resolved due to mixing of the sediment by bottomdwelling organisms. Where they are preserved, laminated sediments act like tree rings to record these seasonal-scale processes, such as plankton blooms and floods, and provide a uniquely high-resolution record of environmental change. In addition, annually laminated or 'varved' sediment sequences act as geochronometers against which other timescales can be tested. Laminated sediments may therefore be used to develop records of interannual and decadal-scale variability which serve to test models of climate change. The authors cover a range of topics that include strategies for study and techniques of analysis. A series of case studies, dealing with a variety of lacustrine and marine records, illustrates the wide potential of laminated sediments as palaeoclimatic and palaeoceanographic indicators.

Book Synopsis What Annually Laminated Sediments Reveal About the History of Environment and Civilization by : Yoshinori Yasuda
Download or read book What Annually Laminated Sediments Reveal About the History of Environment and Civilization written by Yoshinori Yasuda and published by Springer. This book was released on 2015-11-05 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents a proposal for interdisciplinary and international research that uses varve as an essential tool. The discovery and subsequent palaeoenvironmental studies of the annually laminated sediments of Lake Suigetsu (Japan) revealed the directionality of a new discipline in the traditional field of historical science. The historical evidence of environmental changes and natural disasters provided by annually laminated sediments promote an integration of human and natural histories on a common time scale. To explore the impact of climatic changes and natural disasters on civilized society in the present and past, we simply open this door and enter a new phase in world history. The high resolution data about environmental history like climate, sea level, vegetation changes and natural disasters under the most reliable varve chronology will be discussed in relation to the development of human history and the rise and fall of civilizations. The book shows the direction of a new world history and new cosmology of the future civilization in relation to the environmental changes.
Book Synopsis Geomorphology of Proglacial Systems by : Tobias Heckmann
Download or read book Geomorphology of Proglacial Systems written by Tobias Heckmann and published by Springer. This book was released on 2018-11-29 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the recession of alpine glaciers since the end of the Little Ice Age (LIA), which has been accelerating in the past decades. It provides an overview of the research in the field, presenting definitions and information about the different proglacial areas and systems. A number of case studies are from the PROSA project group which encompasses the expertise of geomorphologists, geologists, glaciologists and geodesists. The PROSA joint project (High-resolution measurements of morphodynamics in rapidly changing PROglacial Systems of the Alps) is determined to tackle the problems of geomorphic activity on sediment export through a quantification of sediment fluxes effected by the aforementioned geomorphic processes within the forefield of the Gepatschferner glacier (Central Alps, Austria).

Book Synopsis Sediment Records of Biomass Burning and Global Change by : James S. Clark
Download or read book Sediment Records of Biomass Burning and Global Change written by James S. Clark and published by Springer Science & Business Media. This book was released on 1997-02-20 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass burning profoundly affects atmospheric chemistry, the carbon cycle, and climate and may have done so for millions of years. Bringing together renowned experts from paleoecology, fire ecology, atmospheric chemistry, and organic chemistry, the volume elucidates the role of fire during global changes of the past and future. Topics covered include: the characterization of combustion products that occur in sediments, including char, soot/fly ash, and polycyclic aromatic hydrocarbons; the calibration of these constituents against atmospheric measurements from wildland and prescribed fire emissions; spatial and temporal patterns in combustion emissions at scales of individual burns to the globe.
