Planktic Foraminifers in the Modern Ocean

Planktic Foraminifers in the Modern Ocean PDF Author: Ralf Schiebel
Publisher: Springer
ISBN: 3662502976
Category : Science
Languages : en
Pages : 358

Book Description
This book provides a comprehensive overview of the taxonomy, biology, sedimentation, and carbonate geochemistry of modern species. Students, early career and advanced scientists alike will profit from a broad synthesis of the current understanding of planktic foraminifers as an ecological indicator, biogeochemical factories, and proxies in paleoceanography. The classification of modern species is amply illustrated with electron and light microscope images of morphotypes, addresses the state-of-the-art of molecular genetics of species, and provides a detailed guide for any laboratory analyses. The biology of planktic foraminifers is extensively discussed in chapters dedicated to the cellular ultrastructure, nutrition, symbionts, reproduction, ontogeny, and test architecture. Building on the biological prerequisites, the distribution of planktic foraminifers is discussed at regional to global scale. The geochemistry and sedimentation of tests are considered in relation to the ecology of the living animal. In the final chapter, which examines the most common methods in planktic foraminifer research, hands-on information is provided on sampling, processing and analyzing samples in the laboratory, as well as selected established methods for data interpretation. The various topics discussed in this book are aimed at the application of planktic foraminifers as sensitive indicators of the changing climate and marine environment.

Book Description
In a single volume, the authors bring together a review of current biological understanding of planktonic foraminifera and apply it to developments in sedimentology. With the growing interest in the shells of this class of protozoa as indicators of the history of the earth, revealed through the sedimentary record, a comprehensive analysis of the biology of contemporary foraminifera has become necessary. Main topics covered include Taxonomy, Collecting and Culture Methods, Cellular Ultrastructure, Host and Symbiont Relationships, Trophic Activity and Nutrition, Reproduction, Shell Ontogeny and Architecture, Ecology and Sedimentation and Settlement of Shells.

Foraminiferal Micropaleontology for Understanding Earth’s History

Foraminiferal Micropaleontology for Understanding Earth’s History PDF Author: Pratul Kumar Saraswati
Publisher: Elsevier
ISBN: 0128242302
Category : Science
Languages : en
Pages : 340

Book Description
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

Virtual Paleobiology – Advances in X-Ray Computed Microtomography and 3D Visualization of Fossils PDF Author: Stergios D. Zarkogiannis

ISBN: 2832543901
Category : Science
Languages : en
Pages : 171

Book Description
Emerging technologies are opening new avenues for the study of past and present ecosystems. Computer-aided visualization and analysis of fossil specimens through X-ray tomography has revolutionized the study of organisms. X-ray tomography, or X-ray computed tomography, is a characterization technique for generating 3D information from 2-dimensional X-ray image slices. X-ray imaging is based on the differential absorption or scattering of an X-ray source to reveal internal attributes of biological specimens. High-resolution tomography can retrieve compositional and structural information of small objects or the macrostructure of larger objects non-destructively, allowing fossils to be characterized in three dimensions and in unprecedented detail. This has enabled paleontologists to gain important insights into the anatomy, development, and preservation of specimens. The resulting digital 3D reconstructions can be used in functional analyses to test hypotheses regarding the paleobiology of extinct organisms that could transform our understanding of long-studied fossil groups, and the narratives of organismal and ecological evolution. Furthermore, this proliferation of digital datasets should make the widespread sharing and dissemination of 3D data possible, providing access to rare fossil material worldwide.

The Ioffe Drift

The Ioffe Drift PDF Author: Ivar Murdmaa
Publisher: Springer Nature
ISBN: 3030828719
Category : Science
Languages : en
Pages : 194

Book Description
The Discovery of the calcareous Ioffe Drift in the SW Atlantic in 2010 opens new perspectives in the contourite theory. Although demonstrating similar behavior relative to bottom water dynamics, rather rare and poorly studied calcareous contourites differ from their terrigenous analogs in origin, grain-size distribution, chemical and mineral composition of sedimentary particles. The detailed multidisciplinary study of the Ioffe Drift produces new knowledge on biogenic contourites deposited in pelagic realm, in conditions of low biological productivity and terrigenous material supply, under the influence of the Antarctic Bottom Water flow from the Vema Channel. The major intervals of prevailing erosion are inferred on the drift from 2.51/2.59 to 1.9 Ma and from 1.6 to 0.81 Ma thus indicating strong paleoceanographic changes most likely associated with the reorganization of deep-sea circulation and increased bottom water production in the Southern Ocean during the Early Pleistocene and, in particular, around the Mid-Pleistocene Transition.

Book Description
Natural history collections have recently acquired an unprecedented place of importance in scientific research. Originally created in the context of systematics and taxonomy, they are now proving to be fundamental for answering various scientific and societal questions that are as significant as they are current. Natural History Collections in the Science of the 21st Century presents a wide range of questions and answers raised by the study of collections. The billions of specimens that have been collected from all around the world over more than two centuries provide us with information that is vital in our quest for knowledge about the Earth, the universe, the diversity of life and the history of humankind. These collections also provide valuable reference points from the past to help us understand the nature and dynamics of global change today. Their physical permanence is the best guarantee we have of a return to data and to information sources in the context of open science.
