Book excerpt: Essay from the year 2009 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 1,3, University of Leipzig (Institut für Geophysik und Geologie), course: M.Sc. Modul Paläoklimatologie, language: English, abstract: At the Paleocene/Eocene boundary (55 Ma BP) a general global warming trend was overruled by an outstanding 4-6 °C (Dickens et al. 1997; Zachos et al. 2001) short-term warming event. This information is derived from a -2 to -3‰ negative δ 18O excursion accompanied by an -2.5 ‰ δ13C excursion (Fig.1). Both isotope excursions occur simultaneously and reach their minimal values very rapidly within less than 10 ka. They return to initial values after ~200 ka. PETM climate conditions resulted in extinction of archaic mammals while modern mammalian ancestors have appeared as well as in extinction or temporal disappearance of many deep-sea species (Dickens et al. 1997). δ 18O values of benthic foraminifera of all oceans and planktic foraminifera at high-latitude locations are marked by a sharp decrease (Fig.1) indicating a striking global temperature increase of the deep-sea and high-latitude surface water temperatures (Dickens et al. 1997). A simultaneous negative δ13C excursion is documented in marine as well as in terrestrial environments all over the world. The carbon isotope excursion is attributed to the release of massive quantities of biogenic methane (δ13C = -60‰) adding large amounts of 12C to the inorganic carbon reservoir. Mass balance calculations suggest a transfer of 1400 to 2800 Gt (Dickens et al.1997) respectively 1500 to 2200 Gt (Katz et al. 2001) of CH4 to the ocean/atmosphere system to explain the negative carbon isotope excursion.

Download or read book The Vegetation of Antarctica through Geological Time written by David J. Cantrill and published by Cambridge University Press. This book was released on 2012-11-22 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the paleoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic paleobotany and terrestrial paleoecology.

Download or read book Biogeochemistry of Marine Dissolved Organic Matter written by Dennis A. Hansell and published by Academic Press. This book was released on 2014-10-02 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon in the oceanic water column, posited to be a source of atmospheric climate regulation. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, focuses on the chemical constituents of DOM and its biogeochemical, biological, and ecological significance in the global ocean, and provides a single, unique source for the references, information, and informed judgments of the community of marine biogeochemists. Presented by some of the world's leading scientists, this revised edition reports on the major advances in this area and includes new chapters covering the role of DOM in ancient ocean carbon cycles, the long term stability of marine DOM, the biophysical dynamics of DOM, fluvial DOM qualities and fate, and the Mediterranean Sea. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, is an extremely useful resource that helps people interested in the largest pool of active carbon on the planet (DOC) get a firm grounding on the general paradigms and many of the relevant references on this topic. Features up-to-date knowledge of DOM, including five new chapters The only published work to synthesize recent research on dissolved organic carbon in the Mediterranean Sea Includes chapters that address inputs from freshwater terrestrial DOM

Available in PDF, EPUB and Kindle. Book excerpt: This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.

Available in PDF, EPUB and Kindle. Book excerpt: "The study of climate today seems to be dominated by global warming, but these predictions of climatic models must be placed in their geological, paleo-climatic, and astronomical context to create a complete picture of the Earth's future climate. The Future of the World's Climate presents that perspective with data and projections that have emerged from more technologically advanced and accurate climate modeling"--Publisher's website.
