Available in PDF, EPUB and Kindle. Book excerpt: The book presents an up-to-date, detailed overview of the Quaternary glaciations all over the world, not only with regard to stratigraphy but also with regard to major glacial landforms and the extent of the respective ice sheets. The locations of key sites are included. The information is presented in digital, uniformly prepared maps which can be used in a Geographical Information System (GIS) such as ArcView or ArcGIS. The accompanying text supplies the information on how the data were obtained (geomorphology, geological mapping, air photograph evaluation, satellite imagery), how the features were dated (14C, TL, relative stratigraphy) and how reliable they are supposed to be. All references to the underlying basic publications are included. Where controversial interpretations are possible e.g. in Siberia or Tibet, this is pointed out. As a result, the information on Quaternary glaciations worldwide will be much improved and supplied in a uniform digital format. The information on the glacial limits is compiled in digital form by the coordinators of the project, and is available for download at: http://booksite.elsevier.com/9780444534477/ Completely updated detailed coverage of worldwide Quaternary glaciations Information in digital, uniformly prepared maps which can be used in a GIS such as ArcView or ArcGis Step-by-step guideline how to open and use ArcGis files Possibility to convert the shapefiles into GoogleEarth kmz-files Availability of chronological controls

Download or read book A Chronology of Late Quaternary Southwestern Greenland Ice Sheet Retreat Using Terrestrial and Marine Records written by and published by . This book was released on 2014 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines forcings of southwestern Greenland ice sheet (GrIS) retreat, and the time-scale of ice response to these drivers. Using sediment grain size analyses, planktic foraminifera Neogloboquadrina pachyderma (s) [delta]18O, and planktic foraminifera 14C for southeastern Davis Strait sediment core HU87033-008, early last deglaciation ice retreat is reconstructed. A peak in sediment flux 19-18 ka suggests a southwestern GrIS margin at or near the continental shelf break. Rapid retreat to the middle or inner shelf occurred by 17 ka. This timing, prior to deglacial warming in the region, points to sea level rise as the primary forcing on southwestern GrIS retreat from the outer shelf, over ~1,000 years. Following this early deglacial retreat, the southwestern GrIS maintained a shelf position until withdrawing inland of the modern coastline at 12-11 ka. Ice thinning rates at the coastline from high to low elevations, and retreat inland to the modern ice margin, are calculated using 10Be surface exposure dates from boulders along four transects. Three transects experienced strong marine influence due to extensive fjord systems, whereas the fourth transect experienced weak marine influence. Data from this dissertation demonstrates that thinning and retreat occurred quickly at the sites with marine-terminating ice between 12 and 10.5 ka, concurrent with the rise in Labrador Sea temperatures from glacial-like to interglacial-like conditions. Slow retreat rate at the land-terminating ice margin suggests that warming ocean waters were the dominant forcing on late deglacial retreat of marine-terminating outlet glaciers, which occurred over centuries to ~1,000 years. After the last deglaciation, the GrIS continued to retreat inland, then readvanced during the cooler climate of 4-0.1 ka. The maximum ice position of this late Holocene period is generally considered to be during the Little Ice Age (0.6-0.1 ka). However, 10Be surface exposure dating of boulders associated with the Narsarsuaq moraine in southern Greenland places the maximum ice extent of the Kiagtût sermiat glacier at 1.5 ka. In combination with nearby paleoclimate records, this suggests that southern Greenland may have experienced different temperature trends than that of western Greenland or northwestern Europe, driving ice response on a centennial-scale.

Available in PDF, EPUB and Kindle. Book excerpt: A greater knowledge of the interactions between the Greenland Ice Sheet and climate is critical to understanding the possible impacts of future global warming, including ice sheet contribution to global sea-level rise and perturbations to ocean circulation. Recent acceleration, thinning and retreat of major tidewater glaciers in Greenland and Antarctica during the past two decades demonstrate the potential for ice sheets to respond to climate change much faster than previously assumed. One approach to understanding the role of atmospheric and oceanic warming to ice sheet dynamics is to investigate how ice sheets responded to past periods of climate change. This thesis uses benthic foraminifera as a proxy to reconstruct past changes in the temperature of the relatively warm West Greenland Current, to investigate the possible influence of ocean warming on ice sheet dynamics during the initial marine-based deglaciation phase, and throughout the Holocene, when the ice was positioned close to the present margin. This thesis finds that the marine-based ice sheet in central West Greenland collapsed rapidly due to a combination of high relative sea-level and ice sheet thinning due to climatic warming. Foraminiferal evidence does not support a major influence of ocean forcing on initial deglaciation. However, Holocene changes in the relative temperature of the West Greenland Current may have had a more significant influence on ice stream dynamics following the marine-based ice retreat, when outlet glaciers were positioned within coastal fjords. Changes in the relative temperature of the West Greenland Current are determined?upstream? by wider scale changes in the North Atlantic region.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the second of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared. The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. The last deglaciation is also shown in 500 year time-steps. The digital maps in this volume cover the USA and Canada and include Greenland and Hawaii. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1985, Quaternary Environments represents the culmination of Quaternary research in the region of Baffin Island, Baffin Bay and West Greenland over a period of twenty years and it will serve as a timely and complementary balance to the paleo- oceanographic studies in the NE North Atlantic. The region of Baffin Island, Baffin Bay and West Greenland is probably the best place in the world to examine the interactions between ice, land and oceans on timescales of a few hundred to many thousands of years. Two introductory chapters outline the history of research and the physical background. In Part II the evidence for glacial erosion and deposition over the eastern Canadian Arctic is examined and the history of the Baffin Island continental shelf is described. Part III deals with the paleo- oceanography of Baffin Bay and the Labrador Sea through an examination of deep-sea cores dated by several different methods. In Part IV there is a comprehensive account of the stratigraphy of Baffin Island, Bylot Island, and West Greenland, from the Pliocene to the late Wisconsin. Part V examines the climatic effects of the past 10,000 years, considering evidence from pollen analysis, glacier fluctuations, changes of sea level and the response of early (Eskimo) man. This important volume will interest all quaternary scientists, especially those in glaciology, glacial geology, marine geology, and geomorphology.

Book excerpt: This volume examines the processes responsible for sedimentation in modern glaciomarine environments, and how such modern studies can be used as analogues in the interpretation of ancient glaciomarine sequences. Sediments released from glaciers grounded in tidewater, floating ice shelves, ice tongues, icebergs and sea ice form complex sequences governed by glaciological, oceanographic, sedimentary and biogenic controls. Ten per cent of the world's oceans and epicontinental seas contain such active glacimarine environments, but during Cenozoic glacial periods this area was doubled. This book will, therefore, be of relevance to all scientists concerned with high and middle latitude marine environments. The early chapters are concerned largely with processes of sedimentation in modern glacimarine environments; examples are drawn from Alaska, the Canadian Arctic, Svalbard and Antarctica. Studies of ancient sequences, both Cenozoic and pre-Cenozoic, from the Barents Sea, Greenland, Sweden, Alaska and the northwest European continental shelf, form the latter part of the book.
