This book is the result of ten years of scientific research carried out by the authors on Isla de los Estados. The research includes their doctoral thesis and many published scientific papers related to the island. The book is divided into two principal parts. The first part covers different social and natural aspects of this remote island and includes chapters on the scientific and historical background, physiography with topographical and hydrographical descriptions, climate and oceanographic circulation, vegetation and geology (including stratigraphy, structural geology and geological history). The second part comprises a reconstruction of the paleoenvironmental, paleoclimatic and paleogeographic history of the island from the Last Glacial Maximum to the present, correlating with other paleoecological records from the southern part of Isla Grande de Tierra del Fuego and Patagonia. This second part also includes a geomorphological chapter with a characterization of the principal erosive glacial landforms on Isla de los Estados constructed by means of morphometric analysis, inventories, maps, paleogeographic and glacial models, and a paleoecological chapter evaluating the palaeoenvironment and palaeoclimatic conditions that prevailed during the Late Pleistocene-Holocene times based on pollen and diatom analysis from three 14C-dated peat bogs and lakes. Finally, the book concludes with a review of the island s archaeology and the relationship between the palaeoenvironmental history and human occupation of this island.
Climatologists with an eye on the past have any number of sources for their work, from personal diaries to weather station reports. Piecing together the trajectory of a weather event can thus be a painstaking process taking years and involving real detective work. Missing pieces of a climate puzzle can come from very far afield, often in unlikely places. In this book, a series of case studies examine specific regions across North America, using instrumental and documentary data from the 17th to the 19th centuries. Extreme weather events such as the Sitka hurricane of 1880 are recounted in detail, while the chapters also cover more widespread phenomena such as the collapse of the Low Country rice culture. The book also looks at the role of weather station histories in complementing the instrumental record, and sets out the methods that involve early instrumental and documentary climate data. Finally, the book's focus on North America reflects the fact that the historical climate community there has only grown relatively recently. Up to now, most such studies have focused on Europe and Asia. The four sections begin with regional case studies, and move on to reconstruct extreme events and parameters. This is followed by the role of station history and, lastly, methodologies and other analyses. The editors' aim has been to produce a volume that would be instrumental in molding the next generation of historical climatologists. They designed this book for use by general researchers as well as in upper-level undergraduate or graduate level courses.
Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. T. G. Bonney's The Work of Rain and Rivers was first published in 1912 and reprinted in 1928. It offers a brief yet clear account of the way that rain and rivers act to change the landscape.
Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. First published in 1913, this small volume by Clement Reid was among the first attempts to survey the ancient layers of land surfaces and forests that lie submerged along the coasts and estuaries of Britain. The inconvenient position of these submerged forests made them a little-studied subject, but Reid's consummate and still relevant work shows that they are full of interest for geologists, botanists, zoologists and even archaeologists.
The classic text on coppicing and woodland crafts, redesigned for a new generation of woodspeople. If youâre lucky enough to have access to a patch of woodland, this book contains everything you need to set up, manage and profit from a thriving coppice. But even if you donât, thereâs plenty of information on traditional woodland crafts here for you: learn how to work with bought coppiced wood to make all manner of products, from the archetypal besom broom and humble tent pegs to sturdy gate hurdles. Woodland crafts expert Ray Tabor guides you through a range of heritage woodland conservation methods. He introduces the best tools for each job â the time-honoured woodsmanâs billhook being the most important of all â and the devices youâll need. He shows how to select wood for each purpose, from ash, traditionally used for tool handles, to chestnut for making perfect fences. Thereâs also an in-depth exploration of the essential art of riving (splitting wooden poles by hand). Full of invaluable advice, historical information, useful diagrams and evocative photography, this book will help you reconnect to nature and the environment, and gain immense pleasure from creating beautiful crafted products using heritage methods.
Reports of natural disasters fill the media with regularity. Places in the world are affected by natural disaster events every day. Such events include earthquakes, cyclones, tsunamis, wildfires - the list could go on for considerable length. In the 1990s there was a concentrated focus on natural disaster information and mitigation during the International Decade for Natural Disasters Reduction (IDNDR). The information was technical and provided the basis for major initiatives in building structures designed for seismic safety, slope stability, severe storm warning systems, and global monitoring and reporting. Mitigation, or planning in the event that natural hazards prevalent in a region would suddenly become natural disasters, was a major goal of the decade-long program. During the IDNDR, this book was conceptualized, and planning for its completion began. The editors saw the need for a book that would reach a broad range of readers who were not actively or directly engaged in natural disasters relief or mitigation planning, but who were in decision-making positions that provided an open window for addressing natural disaster issues. Those people were largely elected public officials, teachers, non-governmental organization staff, and staff of faith-based organizations. Those people, for the most part, come to know very well the human and physical characteristics of the place in which they are based. With that local outreach in mind, the editors intended the book to encourage readers to: 1.
Hotspots are enigmatic surface features that are not easily explained in the framework of plate tectonics. Investigating their origin is the goal of this thesis, using field evidence collected in the Cape Verde Islands, a prominent hotspot archipelago in the eastern Atlantic Ocean. The approach taken is to document uplift of the islands relative to sea level and use the uplift features to test various models of hotspot development. Island uplift is thought to arise from the growth of the anomalously shallow seafloor on which the islands rest, known as the bathymetric swell, which is characteristic of hotspots. The work comprises a geological summary and detailed mapping of paleo sea level markers on Cape Verde. Isotopic dating of the markers shows that uplift on the islands over the last 6 Myr is up to 400 m, and that the uplift chronology varies among islands. Two processes act to raise the Cape Verde Islands. The dominant process is one that is local to individual islands. The regional, swell-related component is smaller, and possibly episodic. The observations provide strong constraints on swell development and on hotspot models.
Managed realignment has been a preferred coastal management strategy in England in the 21st century and has also been increasingly implemented elsewhere. Climate change and environmental and financial concerns have led to a shift from the traditional hold-the-line approach of coastal protection towards more flexible soft engineering options. Managed realignment is a relatively new soft engineering alternative aiming to provide sustainable flood risk management with added environmental and socio-economic benefits by creating space for coastal habitats to develop more dynamically. The natural adaptive capacity of coastal habitats and the ecosystem services they provide underpin the sustainability of managed realignment. However, many definitions of managed realignment exist and the understanding of what the term actually represents in practice has evolved through time and varies regionally. This book clarifies the definitions and terminology used in the literature and proposes that managed realignment is used as a general term that encompasses the many different methods of implementation worldwide, including: removal, breach and realignment of defences; controlled tidal restoration (which includes regulated tidal exchange and controlled reduced tide); and managed retreat. These methods of implementation are explained and illustrated with examples from around the world. In addition to a general overview of emerging policies and current practices, specific chapters discuss approaches adopted in different locations, including the Netherlands, the UK and Maui (USA). The UK experience is presented from the perspectives of three sectors: the National Trust (a charity organisation that owns 10% of the coastline of England and Wales), the Environment Agency (the organisation responsible for implementing government policy concerning flood and erosion risk) and a private consultant involved in the planning, design and delivery of managed realignment projects. Taking a wider perspective to consider the range of implementation methods, the viability of managed realignment as a long-term coastal management strategy is discussed. Recent national and regional strategies worldwide give managed realignment an increasing role in climate change and flood risk management. Gaining stakeholders and public support is fundamental for the success of emerging coastal management strategies. However, public perception and stakeholders engagement are often cited as a factor limiting the wider uptake of managed realignment. Results from a recent survey are used to benchmark the current thinking about the potential, the performance and the limitations of managed realignment in the UK and elsewhere. Current opinions about managed realignment are often not clearly defined, partly due to many projects being relatively recent. There is a general perception of great potential to provide sustainable flood risk management with added environmental benefits. However, the views of stakeholders are considerably more negative and notably contrast with the views of practitioners and researchers. The only clear and dominant agreement across all groups of respondents is that better understanding about the long-term evolution of sites is needed. "
Islands represent unique opportunities to examine human interaction with the natural environment. They capture the human imagination as remote, vulnerable and exotic, yet there is comparatively little understanding of their basic geology, geography, or the impact of island colonization by plants, animals and humans. This detailed study of island environments focuses on nine island groups, including Hawaii, New Zealand and the British Isles, exploring their differing geology, geography, climate and soils, as well as the varying effects of human actions. It illustrates the natural and anthropogenic disturbances common to island groups, all of which face an uncertain future clouded by extinctions of endemic flora and fauna, growing populations of invasive species, and burgeoning resident and tourist populations. Examining the natural and human history of each island group from early settlement onwards, the book provides a critique of the concept of sustainable growth and offers realistic guidelines for future island management.
In a book that is part memoir and part history, David Roberts looks back at his personal relationship to extreme risk and tries to make sense of why so many have committed their lives to the desperate pursuit of adventure. In the wake of his diagnosis with throat cancer, Roberts seeks the answer with sharp new urgency. He explores his own lifelong commitment to adventuring, as well as the cultural contributions of explorers throughout history. He looks at what it meant in 1911 for Amundsen to reach the South Pole or in 1953 for Hillary and Norgay to summit the highest point on earth. And he asks what the future of adventure is in a world we have mapped and trodden all the way to the most remote corners of the wilderness.
One of the world's natural wonders, the Great Barrier Reef stretches more than 2000 kilometres in a maze of coral reefs and islands along Australia's north-eastern coastline. Now unfolding the fascinating story behind its mystique this 2002 book provides for the first time a comprehensive cultural and ecological history of European impact, from early voyages of discovery to developments in Reef science and management. Incisive and a delight to read in its thorough account of the scientific, social and environmental consequences of European impact on the world's greatest coral reef system, this extraordinary book is sure to become a classic.
Selected Climbs: Mont Blanc & the Aiguilles Rouges presents the best rock climbs in the Mont Blanc range and on the Aiguilles Rouges, from F4 to F6a+. The selection is based on purely hedonistic criteria, including the beauty of the cliff, the variety of the climbing and the quality of the rock. The emphasis is on enjoyable climbs with easy access and descents. The routes cover a variety of rock types, climbing styles and protection (natural and fixed). All the routes are of moderate difficulty and can be done comfortably in a day without the need to carry heavy or bulky gear. Written by local climbers Jean-Louis Laroche and Florence Lelong, this selection of sixty climbs on forty summits in seventeen areas around the Chamonix valley features established classics and recent additions. Included are Marchand de Sable on the Tour Rouge, the Rebuffat Route on the Aiguille du Midi, and the Frison-Roche route of the south-east face of the Brevent, plus many more. Each route features technical notes, a detailed topo and route description, and photos illustrating the climb's unique character.
Terrestrial mass movements (i.e. cliff collapses, soil creeps,
mudflows, landslides etc.) are severe forms of natural disasters
mostly occurring in mountainous terrain, which is subjected to
specific geological, geomorphological and climatological
conditions, as well as to human activities. It is a challenging
task to accurately define the position, type and activity of mass
movements for the purpose of creating inventory records and
potential vulnerability maps. Remote sensing techniques, in
combination with Geographic Information System tools, allow
state-of-the-art investigation of the degree of potential mass
movements and modeling surface processes for hazard and risk
mapping. Similarly, through statistical prediction models, future
mass-movement-prone areas can be identified and damages can to a
certain extent be minimized. Issues of scale and selection of
morphological attributes for the scientific analysis of mass
movements call for new developments in data modeling and
spatio-temporal GIS analysis.
This highly practical handbook is an exhaustive treatment of
eddy covariance measurement that will be of keen interest to
scientists who are not necessarily specialists in micrometeorology.
The chapters cover measuring fluxes using eddy covariance
technique, from the tower installation and system dimensioning to
data collection, correction and analysis.
It is an honor and pleasure for me to write the foreword of this book comprising the of Forest Resources for proceedings of the Fourth Symposium on the Improvement Recyclable Forest Products. The symposium was organized by Dr. Toshihiro Ona, Associate Professor at the Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University, Japan, as part of the "Development of Forest Resources with High Performance for Paper Recycling" research project. This was supported by the Core Research for Evolutional Science and Technology (CREST) team at the Japan Science and Technology Agency Foundation (lST) and by Kyushu University. As a colleague of Dr. Ona, I commend his efforts in organizing the symposium and editing this book. In the forest, there is a multitude of resources, including trees, herbal plants, fruits, fungi, mammals, birds, insects, fishes, reptiles, water, landscapes, and tourist attractions. Nowadays, even the environment is regarded as a kind of forest resource. These resources can provide a diversity of forest products, such as timber for buildings, pulp and paper, charcoal, herbal medicines, wild vegetables, animal protein, edible mushrooms, and nonwoody fibers. From these resources, major forest products are produced using various species of trees. For example, softwood is suitable as building material, while hardwood is suitable for furniture production; pulp and paper are produced from both softwood and hardwood. Therefore, forest locations and forest management methods should vary according to the tree species used for production of different forest products.
While deforestation continues at an alarming rate around the world, discussions on the range of underlying causes continue. The premise is that studying successful transitions from deforestation to sustainable forestry ex post in Finland can provide novel insights into how deforestation in the tropics might be reduced in the future. Our fundamental question here is why Finland succeeded to stop deforestation for a century ago and why not the same is feasible in the contemporary tropical countries? This book presents a novel integrated theory within which this case study on Finland and contemporary modeling of underlying causes of tropical deforestation are developed. Finland remains the world's second largest net exporter of forest products, while maintaining the highest forest cover in Europe. A transition from deforestation to sustainable industrial forestry took place in Finland during the first part of the 20th century. The underlying causes of this transition are compared via our theory with deforestation in 74 contemporary tropical countries. Both appear similar and support our theory. The interaction of public policies and market institutions has appeared to be critical during this transition. The study's findings suggest that private forest ownership with a continuous increase in the real value of forests and alleviation of poverty under non-corruptive conditions has been a necessary, but not a sufficient, condition for this transition. In a parallel way public policies have also proved to be a necessary, but not sufficient, condition in this transition. The conclusion is that socialistic forestry along with corruption is artificially maintaining too low values in the tropical forests. The opportunity cost of sustainable forestry remains too high and deforestation by extensification of agriculture therefore continues. The prevailing socialistic forestry with dominating public forest ownership is by purpose maintaining administratively set low stumpage prices leading to low value of forests, wide corruption and continuous forest degradation and deforestation. An effective remedy - to raise the value of forests - is found to be within forestry.
The author of the standard early twentieth-century textbook on fossil plants, A. C. Seward (1863 1941) was Professor of Botany at Cambridge, Master of Downing College and Vice-Chancellor of Cambridge University. This account of his first research trip to Greenland is an evocative portrait of the country, its immense and sublime landscape, its people, and life on the Danish scientific station. This little book, written in an engaging conversational tone, conveys Seward's enthusiasm for Greenland. It includes an explanation for non-specialists of some of Seward's findings relating to fossil plants found there, which provide evidence that the country had a much milder climate in previous geological periods. Seward's own photographs are a fascinating record of the traditional life of the Inuit population as it then survived, as well as the rugged scenery of icebergs and glaciers.
The publications of the Hakluyt Society (founded in 1846) made available edited (and sometimes translated) early accounts of exploration. The first series, which ran from 1847 to 1899, consists of 100 books containing published or previously unpublished works by authors from Christopher Columbus to Sir Francis Drake, and covering voyages to the New World, to China and Japan, to Russia and to Africa and India. Robert Hues (1553 1632) was an English mathematician and geographer who published this work in 1594 to explain the use of the new terrestrial and celestial globes devised by Emery Molyneux in 1592. These were the first English manufactured globes and were popular with both navigators and students. The five parts of this book describe these globes and explain their use in calculating fundamental navigational points, providing valuable insights into their appearance and practical application in early sixteenth-century navigation.
Cyril Crossland (1878 1943) was Director of the Sudan Pearl Fishery between 1905 and 1922. At this time, the British colonial government had taken charge of running the fishery, with local fishermen as employees. A marine biologist and zoologist, Crossland was praised in his obituary in the journal Nature as 'one of the last explorer-naturalists of the Darwin type'. This book is both an account of his life in the Sudan and a scientific survey of the coral reefs on the Red Sea coast. It offers a lively description of the region, its people and customs, and a clear, accessible explanation of the development of coral reefs. In Crossland's time this region had not been fully mapped by Western explorers and this study was an important contribution to knowledge. The book is illustrated with many of Crossland's own photographs of landscapes and people and his diagrams of the coral reefs.
This volume describes important sites in the Pleistocene deposits of the Thames terrace system laid down by the Thames and its tributaries. It correlates the Thames sequence with deposits found elsewhere in Britain, on the European continent and on the ocean floor.
Forest ecosystems are characterized by a steady change in their structure of function. Natural developments are more and more radically disturbed by human impact. Air pollution leads to soil acidification, change in nutrient budget and to a decreasing vitality of the trees. Forest management can prevent natural succession and often leads to less stable forests. In this book, selected results of 10 years of interdisciplinary ecosystem research are presented. Not only growth and physiological reactions on environmental stress, but also natural succession processes are described and analysed. Besides the description of forest development processes, based on longterm experiments and observation, conclusions for practical forest management are given.
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists, soil scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B. B * Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D.D. Hook and R.M.M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com-: prehensive and balanced coverage on the status of ecology and management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
Sedimentation and Tectonics in Rift Basins: Red Sea - Gulf of Aden presents new case studies and synthesises the results of recent research on the sedimentological evolution of the Red Sea - Gulf of Aden rift system. This rift basin is generally regarded as the best natural geological laboratory in the world in which to study the processes of rift formation. Uplift of the rift margins in an arid climate results in extensive three-dimensional exposures of pre- and syn-rift strata and associated structures. These serve as analogues for the understanding and hydrocarbon exploration of deeper buried rift-systems on continental margins such as the North Sea and the Atlantic margins. The Red Sea - Gulf of Aden rift is also exceptional in that its stratigraphy spans all stages from pre-rift environments, syn-rift continental to marine environments through the rift to drift transition to post-rift sea-floor spreading. The work is arranged in eight sections: following a review of the sedimentology and stratigraphy of rift basins, the magmatism and structural evolution of the Red Sea - Gulf of Aden rift is reviewed. Subsequently, new case studies are presented of the early rifting environment, syn-rift sedimentation, tectonics and diagenesis, evaporites and salt tectonics. Post-rift sediments of the axial trough are then discussed along with studies of reefs, coastal zone and shelf sediments, and the tectonic geomorphology of the rift margin escarpment. This work results from extensive new research in the rift basin largely carried out under collaborative research projects by European and Middle Eastern geologists. It will be an invaluable reference work for geoscientists in the hydrocarbon, groundwater and mineral extraction industries, as well as for researchers in university departments of earth sciences, mining and physical geography.
This Brief deals with the reconstruction of Holocene paleoenvironment in the central part of Bangladesh in relation to relative sea-level (RSL) changes which is 200 km north from the present coastline. Lithofacies characteristics, mangal peat, diatom and paleophysiographical evidences were considered to reconstruct the past position and C-14 ages were used to determine the time of formation of the relative sea-level during the Holocene. With standard reference datum the required m.s.l. at the surface of five sections are calculate and the RSL curve suggests that Bangladesh has experienced two mid Holocene RSL transgressions punctuated by regressions. The abundant marine diatom and mangrove pollens indicates that the highest RSL transgression in Bangladesh is around 6000 cal BP which is attained at least 4.5 to 5m higher than the modern m.s.l. After this phase, the relative sea-level started to fall and consequently a freshwater peat developed around 5980 5700 cal BP. The abundant mangrove pollens in salt-marsh succession shows the regression around 5500 cal BP and, the height was 1 2 m higher than the modern sea level. These and more interesting findings are discussed in this Brief.
In Chapter 1 the methodological principles of systemization and visualization of multidimensional ecological information for its operational dissemination among potential users are stated. Their realization results in creation of the geographic-and ecologic model of marine basin as an information base for diagnosis of the marine ecosystem state, estimation of consequences of economic activity, and modelling of its changes with the use of mathematical tools. In Chapter 2 the geographic-and-ecological aspects of mathematical modelling of marine ecosystems, the possibilities and peculiarities of the most adequate models, the Russian hydrodynamic model of oil spills "SPILLMOD" and hydroecological model of organogenic compound transformation in the sea, are investigated. In the following six Chapters the examples of practical realization of geographic-and-ecological (as information source) and mathematical (as computing apparatus) modelling at the investigations of specific ecological problems associated with consequences of natural hazards and economic activity on aquatory and within the whole Black Sea basin are given.
