Download or read book Applications of Non-Pollen Palynomorphs written by F. Marret and published by Geological Society of London. This book was released on 2021-10-29 with total page 358 pages. 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.
Book Synopsis The Paleocene Eocene Thermal Maximum in the Hanna Basin, WY by : Caroline Pew
Download or read book The Paleocene Eocene Thermal Maximum in the Hanna Basin, WY written by Caroline Pew and published by . This book was released on 2013 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The P-E boundary, approximately 56 Ma, coincides with a global climatic event, the Paleocene-Eocene Thermal Maximum (PETM). The PETM is believed to have resulted from a 2-8 fold increase in atmospheric pCO2 in less than 10,000 years, which resulted in increased temperatures of 5-8°C globally. The PETM is an event of great interest as it is believed to be the best ancient analogue for modern climate change. This study aims to more precisely pinpoint the stratigraphic location of the PETM in the Hanna Formation in the Hanna Basin, WY. Previous studies have identified the late Paleocene at 2350 meters above the base of the section and the early Eocene as 2800 meters above the base of the section. In order to accomplish this, organic carbon isotopes from carbonaceous shales and coal deposits were measured in order to establish the presence of the characteristic CIE associated with the PETM and the P-E. Palynological samples were also extracted from carbonaceous shales and coals in order to determine the presence of the index pollen, which were used as biostratigraphic markers to determine the exact placement of the P-E boundary within the section. Additionally, pollen abundance and occurrence were determined throughout the section in order to see if the palynological record suggests paleoecological changes associated with warming at the PETM. Results show an approximately -2 / shift in organic carbon isotopic signature between approximately 2600-2650 meters above the base of the Hanna Formation. Platycarya platycaryoides pollen first occurs just down section of the observed CIE in organic carbon, first appearing at 2540 meters above the base of the section. The first occurrence of Platycarya platycaryoides near the observed carbon isotope excursion suggests that the onset of the PETM and the P-E boundary in the Hanna Basin are located between 2540 and 2650 meters. Thus, this study succeeded in more precisely locating the PETM with in the Hanna Formation. Moreover, this study shows that the Hanna Basin records the PETM event over a greater thickness of section with higher stratigraphic resolution than adjacent basins with a disjunct first occurrence of P-E indicator palynomorphs and the characteristic negative carbon isotope excursion of the PETM. Thus the Hanna Basin reveals greater biogeochemical complexity than other adjacent basins and suggests that either local factors such as old heavy carbon erosion, early floral immigration or changing environmental circumstances complicated the local record, or that greater stratigraphic resolution indicates that biotic change and carbon cycle shifts were not coincident. If the latter, then rapid climatic warming may have post-dated major biological perturbations, which has implications for modern global warming.
