Book Synopsis Biogeochemical Controls on Palaeoceanographic Environmental Proxies by : William E. N. Austin
Download or read book Biogeochemical Controls on Palaeoceanographic Environmental Proxies written by William E. N. Austin and published by Geological Society of London. This book was released on 2008 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of our information about the evolution of Earth's ocean-climate system comes from the analysis of sediments laid down in the past. For example, the microfossil assemblage reflects the temperature, salinity and nutrient abundance of the water in which the organisms lived, while the chemical and isotopic composition of biogenic carbonates may be used to reconstruct past variations in the operation of the carbon cycle, as well as changes in ocean circulation. Nevertheless, understanding the link between these sediment variables (or 'proxies') and environmental conditions is not straightforward. This volume adopts a novel approach by bringing together palaeontologists, geochemists and palaeoceanographers, who contribute evidence that is required to better constrain these proxies. Topics include: (i) processes of biomineralization, and their effect on the chemical and isotopic composition of different organisms; (ii) proxy validation, including field, laboratory and theoretical studies; (iii) the links between modern and fossil organisms

This book was released on 2021-06-12 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foraminiferal Micropaleontology for Understanding Earth’s History incorporates new findings on taxonomy, classification and biostratigraphy of foraminifera. Foraminifera offer the best geochemical proxies for paleoclimate and paleoenvironment interpretation. The study of foraminifera was promoted by oil exploration due to its exceptional use in subsurface stratigraphy. A rapid technological development in the past 20 years in the field of imaging microfossils and in geochemical microanalysis have added novel information about foraminifera. Foraminiferal Micropaleontology for Understanding Earth’s History builds an understanding of biology, morphology and classification of foraminifera for its varied applications. In the past two decades, a phenomenal growth has occurred in geochemical proxies in shells of foraminifera, and as a result, crucial information about past climate of the earth is achieved. Foraminifera is the most extensively used marine microfossils in deep-time reconstruction of the earth history. Its key applications are in paleoenvironment and paleoclimate interpretation, paleoceanography, and biostratigraphy to continuously improve the Geologic Time Scale. Provides an overview of the Earth history as witnessed and evidenced by foraminifera Discusses a variety of geochemical proxies used in reconstruction of environment, climate and paleobiology of foraminifera Presents a new insight into the morphology and classification of foraminifera by modern tools of x-ray microscopy, quantitative methods, and molecular research

Book Synopsis Ammonoid Paleobiology: From anatomy to ecology by : Christian Klug
Download or read book Ammonoid Paleobiology: From anatomy to ecology written by Christian Klug and published by Springer. This book was released on 2015-07-22 with total page 943 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.
Book Synopsis Approaches to Study Living Foraminifera by : Hiroshi Kitazato
Download or read book Approaches to Study Living Foraminifera written by Hiroshi Kitazato and published by Springer Science & Business Media. This book was released on 2014-01-23 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foraminiferal cultures now serve as tools for researching biological, environmental, and geological topics. However, the biological backgrounds, in particular the natural histories of foraminifera, largely remain unclear. It is also true that the different techniques used in different subdisciplines are a setback to fully understanding the subject. Taken together, these factors prevent progress in experimental approaches to foraminiferal studies. This book aims to share and exchange knowledge between researchers from different subdisciplines, and the book should interest not only foraminiferal researchers but also scientists who are working with marine organisms to explore questions in relation to biology, geology, and oceanography.

Book Synopsis Boron Proxies in Paleoceanography and Paleoclimatology by : Bärbel Hönisch
Download or read book Boron Proxies in Paleoceanography and Paleoclimatology written by Bärbel Hönisch and published by John Wiley & Sons. This book was released on 2019-02-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic carbon dioxide emissions do not only warm our planet but also acidify our oceans. It is currently unclear to which degree Earth’s climate and marine life will be impacted by these changes but information from Earth history, particularly the geochemical signals of past environmental changes stored in the fossil remains of marine organisms, can help us predict possible future changes. This book aims to be a primer for scientists who seek to apply boron proxies in marine carbonates to estimate past seawater carbonate chemistry and atmospheric pCO2. Boron proxies (δ11B and B/Ca) were introduced nearly three decades ago, with subsequent strides being made in understanding their mechanistic functioning. This text reviews current knowledge about the aqueous systematics, the inorganic and biological controls on boron isotope fractionation and incorporation into marine carbonates, as well as the analytical techniques for measurement of boron proxies. Laboratory and field calibrations of the boron proxies are summarized, and similarities between modern calibrations are explored to suggest estimates for proxy sensitivities in marine calcifiers that are now extinct. Example applications illustrate the potential for reconstructing paleo-atmospheric pCO2 from boron isotopes. Also explored are the sensitivity of paleo-ocean acidity and pCO2 reconstructions to boron isotope proxy systematics that are currently less well understood, including the elemental and boron isotopic composition of seawater through time, seawater alkalinity, temperature and salinity, and their collective impact on the uncertainty of paleo-reconstructions. The B/Ca proxy is based on the same mechanistic principles as the boron isotope proxy, but empirical calibrations suggest seawater pH is not the only controlling factor. B/Ca therefore has the potential to provide a second carbonate parameter that could be paired with δ11B to fully constrain the ocean carbonate system, but the associated uncertainties are large. This text reviews and examines what is currently known about the B/Ca proxy systematics. As more scientists embark on characterizing past ocean acidity and atmospheric pCO2, Boron in Paleoceanography and Paleoclimatology provides a resource to introduce geoscientists to the opportunities and complications of boron proxies, including potential avenues to further refine them.
Book Synopsis Reconstructing Quaternary Environments by : J. John Lowe
Download or read book Reconstructing Quaternary Environments written by J. John Lowe and published by Routledge. This book was released on 2014-10-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of Reconstructing Quaternary Environments has been completely revised and updated to provide a new account of the history and scale of environmental changes during the Quaternary. The evidence is extremely diverse ranging from landforms and sediments to fossil assemblages and geochemical data, and includes new data from terrestrial, marine and ice-core records. Dating methods are described and evaluated, while the principles and practices of Quaternary stratigraphy are also discussed. The volume concludes with a new chapter which considers some of the key questions about the nature, causes and consequences of global climatic and environmental change over a range of temporal scales. This synthesis builds on the methods and approaches described earlier in the book to show how a number of exciting ideas that have emerged over the last two decades are providing new insights into the operation of the global earth-ocean-atmosphere system, and are now central to many areas of contemporary Quaternary research. This comprehensive and dynamic textbook is richly illustrated throughout with full-colour figures and photographs. The book will be of interest to undergraduates, postgraduates and professionals in Earth Science, Environmental Science, Physical Geography, Geology, Botany, Zoology, Ecology, Archaeology and Anthropology
Book Synopsis Biomineralization Sourcebook by : Elaine DiMasi
Download or read book Biomineralization Sourcebook written by Elaine DiMasi and published by CRC Press. This book was released on 2014-02-25 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: What does it mean to be at the forefront of a characterization technique? Novel implementation and research, finding new ways to visualize composites, and new techniques all play a role. Yet with the myriad of advances in the field, keeping up with new and advanced techniques, often from many different areas, has become a challenge. Biomineralization Sourcebook: Characterization of Biominerals and Biomimetic Materials emphasizes the interplay between multiple techniques at their current frontiers and explores how such studies may be carried out. The book addresses atomic and molecular structure: how it is described, detected, and assessed for importance. It then highlights additional measurements especially well-suited to looking at two- and three-dimensional systems with heterogeneous, if not hierarchical, structure. These systems enable particular aspects of biominerals and biomimetic models to be scrutinized. The text presents state-of-the-art methods to assess properties of the composite, and represents current approaches and aspirations to measuring entire biological working structures while retaining as much fine-grained biophysical information as possible. In all these chapters, authors showcase discoveries from their own programs. Along the way, the book takes you on a tour from microscopy's eighteenth century roots, to the recent literature and diverse research programs of the contributing investigators, to the multi-million dollar National Laboratory facilities that all play their roles to illuminate the ever-fascinating biominerals. A snapshot of the state of the art in a spectrum of experimental techniques applied to a common interdisciplinary goal, where the ability to use the more advanced techniques often requires funding for collaboration and travel, the book will deepen the appreciation for the massive interdisciplinary effort underway, educate researchers across the field, and motivate new collaborations.

Book Synopsis Understanding Earth's Deep Past by : National Research Council
Download or read book Understanding Earth's Deep Past written by National Research Council and published by National Academies Press. This book was released on 2011-08-02 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.
