Download or read book Atlas of Submarine Glacial Landforms written by J.A. Dowdeswell and published by Geological Society of London. This book was released on 2016-12-16 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.
Download or read book Glaciated Margins written by D.P. Le Heron and published by Geological Society of London. This book was released on 2019-04-08 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the sedimentary and geophysical archive of glaciated margins is a complex task that requires integration and analysis of disparate sedimentological and geophysical data. Their analysis is vital for understanding the dynamics of past ice sheets and how they interact with their neighbouring marine basins, on timescales that cannot be captured by observations of the cryosphere today. As resources, sediments deposited on the inner margins of glaciated shelves also exhibit resource potential where more sand-dominated systems occur, acting as reservoirs for both hydrocarbons and water. This book surveys the full gamut of glaciated margins, from deep time (Neoproterozoic, Ordovician and Carboniferous–Permian) to modern high-latitude margins in Canada and Antarctica. This collection of papers is the first attempt to deliberately do this, allowing not only the similarities and differences between modern and ancient glaciated margins to be explored, but also the wide spectrum of their mechanisms of investigation to be probed. Together, these papers offer a high-resolution, spatially and temporally diverse blueprint of the depositional processes, ice sheet dynamics, and basin architectures of the world’s former glaciated margins; a vital resource in advancing understanding of our present and future marine-terminating ice sheet margins.

Download or read book Landscapes and Landforms of Eastern Canada written by Olav Slaymaker and published by Springer Nature. This book was released on 2020-02-13 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: This critical book focuses on the geomorphological landscapes of eastern Canada and provides a companion volume to “Landscapes and Landforms of Western Canada” (2017). There are a number of unique characteristics of eastern Canada’s landscapes, notably its magnificent coastlines, the extraordinary variety and extent of wetlands, the huge Great Lakes-St. Lawrence basin, the high incidence of meteorite craters, the spectacular Niagara Falls, urban karst in Montreal and Ottawa, youthful, glaciated karst in Ontario, Newfoundland, Quebec and Nova Scotia, the ubiquitous permafrost terrain of Nunavut, Labrador and northern Quebec and the magnificent arctic fjords and glaciers. Looking at coastlines, the tidal extremes of the Bay of Fundy are world renowned; the structural complexity of the island of Newfoundland is less well known, but produces an astounding variety of coastlines in close succession; the arctic fjordlands of Baffin and Ellesmere islands and the extravagant raised beaches of Hudson Bay bear comparison with the classic fjords of Norway and the Baltic Sea raised beaches. As for wetlands, there are distinctive Arctic, Subarctic, Boreal, Eastern Temperate and Atlantic wetlands, and their extent is second only to those of Russia. In the Hudson and James Bay regions, between 75-100% of the terrestrial surface is comprised of wetlands. One of North America’s largest river basins, the Great Lakes-St. Lawrence basin, has its source in Minnesota, straddles the USA-Canada border and debouches into Quebec as the St. Lawrence River and evolves through its estuary into the Gulf of St. Lawrence, a journey of almost 5,000 km. As far as meteorite craters are concerned, 10% of the world’s total are located in eastern Canada, including some of the largest and most complex landforms. They are preserved preferentially in the ancient Shield terrain of Quebec. Finally, the three million km2 of permafrost controlled relief in eastern Canada serves as a reminder of the vulnerability of eastern Canada’s landscapes to climate change. Effects of warming are expressed through thawing of the permafrost, disruption of transportation corridors and urban construction problems, ever-present geomorphic hazards.

Download or read book Landscapes and Landforms of the Central Sahara written by Jasper Knight and published by Springer Nature. This book was released on 2024-02-03 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the Central Sahara region, bringing together an unprecedented combination of diverse and often historic research published in different languages in order to describe its varied landscapes and landforms. The Central Sahara region consists of Libya, Algeria, Mali, Niger and Chad, countries that share similar landscape histories and common landscape traits, including massifs, sand seas, paleowater features and large depressions. Furthermore, human settlement of this region goes hand-in-hand with climate and environmental changes and landscape evolution during the Holocene and earlier; hence, Central Saharan landscapes and landforms provide valuable insights into landscape–human relationships over long timescales. The book offers a comprehensive yet accessible reference source, drawing on both past and present interdisciplinary research and gathering the insights of authors from many different countries to explore a region that has largely been overlooked in available literature.
Download or read book Subaqueous Mass Movements and Their Consequences written by D.G. Lintern and published by Geological Society of London. This book was released on 2019-09-25 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges facing submarine mass movement researchers and engineers are plentiful and exciting. This book follows several high-profile submarine landslide disasters that have reached the world’s attention over the past few years. For decades, researchers have been mapping the world’s mass movements. Their significant impacts on the Earth by distributing sediment on phenomenal scales is undeniable. Their importance in the origins of buried resources has long been understood. Their hazard potential ranges from damaging to apocalyptic, frequently damaging local infrastructure and sometimes devastating whole coastlines. Moving beyond mapping advances, the subaqueous mass movement scientists and practitioners are now also focussed on assessing the consequences of mass movements, and the measurement and modelling of events, hazard analysis and mitigation. Many state-of-the-art examples are provided in this book, which is produced under the auspices of the United Nations Educational, Scientific and Cultural Organisation Program S4SLIDE (Significance of Modern and Ancient Submarine Slope LandSLIDEs).

Download or read book Submarine Mass Movements and their Consequences written by Geoffroy Lamarche and published by Springer. This book was released on 2015-10-02 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive collection of state-of-the-art studies of seafloor slope instability and their societal implications. The volume captures the most recent and exciting scientific progress made in this research field. As the world’s climate and energy needs change, the conditions under which slope instability occurs and needs to be considered, are also changing. The science and engineering of submarine – or more widely subaqueous – mass movements is greatly benefiting from advances in seafloor and sub-seafloor surveying technologies. Ultra-high-resolution seafloor mapping and 3D seismic reflection cubes are becoming commonly available datasets that are dramatically increasing our knowledge of the mechanisms and controls of subaqueous slope failure. Monitoring of slope deformation, repeat surveying and deep drilling, on the other hand, are emerging as important new techniques for understanding the temporal scales of slope instability. In essence, rapid advances in technology are being readily incorporated into scientific research and as a result, our understanding of submarine mass movements is increasing at a very fast rate. The volume also marks the beginning of the third IGCP project for the submarine mass movement research community, IGCP-640 S4SLIDE (Significance of Modern and Ancient Submarine Slope LandSLIDEs). The Submarine Mass Movements and Their Consequences symposium is the biannual meeting under the IGCP umbrella.

Download or read book The Changing Role of Geological Surveys written by P.R. Hill and published by Geological Society of London. This book was released on 2020-12-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.

Download or read book The Sea Kings written by R. Andrew McDonald and published by Birlinn Ltd. This book was released on 2020-05-28 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The archipelagic kingdoms of Man and the Isles that flourished from the last quarter of the eleventh century down to the middle of the thirteenth century represent two forgotten kingdoms of the medieval British Isles. They were ruled by powerful individuals, with unquestionably regnal status, who interacted in a variety of ways with rulers of surrounding lands and who left their footprint on a wide range of written documents and upon the very landscapes and seascapes of the islands they ruled. Yet British history has tended to overlook these Late Norse maritime empires, which thrived for two centuries on the Atlantic frontiers of Britain. This book represents the first ever overview of both Manx and Hebridean dynasties that dominated Man and the Isles from the late eleventh to the mid-thirteenth centuries. Coverage is broad and is not restricted to politics and warfare. An introductory chapter examines the maritime context of the kingdoms in light of recent work in the field of maritime history, while subsequent chronological and narrative chapters trace the history of the kingdoms from their origins through their maturity to their demise in the thirteenth century. Separate chapters examine the economy and society, church and religion, power and architecture.
