Available in PDF, EPUB and Kindle. Book excerpt: Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field*Up-to-date information and references*Effective handbook and primary research reference for both experienced practitioners and newcomers

Book excerpt: Studies of aeolian sediments, both ancient and modern, have exhibited a number of important conceptual advances in recent years. In particular, there has been a move away from descriptions of sediments, bedforms and sedimentary environments toward a new emphasis on the dynamics of aeolian depositional systems at different temporal and spatial scales, and their response to external changes in sea levels, regional and global climates and tectonics. This Special Publication contains a selection of papers that were presented at the Symposium "Aeolian Sediments: Ancient and Modern" held in 1990. It also includes a number of contributions from authors who were not able to attend the meeting, but whose work reflects important aspects of contemporary research in aeolian sedimentology. State-of-the-art research papers in aeolian sedimentology International, expert authorship Of relevance to modern concerns about global climate change If you are a member of the International Association of Sedimentologists, for purchasing details, please see: http://www.iasnet.org/publications/details.asp?code=SP16
Download or read book Anti personnel Landmine Detection for Humanitarian Demining written by Katsuhisa Furuta and published by Springer Science & Business Media. This book was released on 2009-01-24 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anti-personnel Landmine Detection for Humanitarian Demining reports on state-of-the-art technologies developed during a Japanese National Research Project (2002–2007). The conventional method of landmine detection is using metal detectors to sense the metal in mines, but often other metal fragments in minefields camouflage landmines and hinder progress using this form of demining. The challenge is to develop detection systems that can discriminate between AP landmines and random metal fragments. The JST adopted research proposals and the results are reported here. This book concentrates on aspects of three approaches to AP mine detection: enhancing and confirming the results of metal-detection scans using GPR; using robot vehicles and manipulators to operate within minefields remotely; and methods of sensing the explosives within mines. Results are presented in the fields of GPR, nuclear quadrupole resonance, neutron thermal analysis and biosensors. The integration of these methods for workable robot operation is demonstrated. The project was carried out in conjunction with mine action centers in Croatia, Cambodia and Afghanistan. Evaluation data from field trials are also given.
Download or read book Ground penetrating Radar for Geoarchaeology written by Lawrence B. Conyers and published by John Wiley & Sons. This book was released on 2016-01-19 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has long been a strong collaboration between geologists and archaeologists, and the sub-field of geoarchaeology is well developed as a discipline in its own right. This book now bridges the gap between those fields and the geophysical technique of ground-penetrating radar (GPR), which allows for three-dimensional analysis of the ground to visualize both geological and archaeological materials. This method has the ability to produce images of the ground that display complex packages of materials, and allows researchers to integrate sedimentary units, soils and associated archaeological features in ways not possible using standard excavation techniques. The ability of GPR to visualize all these buried units can help archaeologists place ancient people within the landscapes and environments of their time, and understand their burial and preservation phenomena in three-dimensions. Readership: Advanced students in archaeology and geoarchaeology, as well as practicing archaeologists with an interest in GPS techniques.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis uses Ground Penetrating Radar (GPR) and traditional coring methods to quantify Holocene sedimentation rates in the Trinity River Delta, Texas. Results showed that, while GPR is useful in determining subsurface stratigraphy in coarse-grained environments such as sand bars, it is not useful for subsurface investigations in marshes, where high clay and water content of the sediments attenuate the GPR signal. Radiocarbon dating of shell fragments recovered from sediment cores (292-536cm) ranged from 2.8 to 3.2 Ka. Mean sediment accumulation rates varied between 1.2 and 1.8 mm yr-1 for two areas of the delta, consistent with previous research. At these rates, modern sediment input from the Trinity River is inadequate to account for sediment accretion in the delta. Therefore, other non-fluvial sediment sources must be contributing to the accretion of sediment within the delta.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground penetrating radar (GPR) is a relatively newly developed high-frequency electromagnetic technique that has been widely used in the shallow subsurface investigation for the last few decades. Recently, a GPR survey of a small organic-rich post-glacial lake (Grassy Pond) in Eastern Newfoundland shows significant continuous laminations within the lake sediments in the GPR profiles. Since there have been very few GPR stratigraphy studies of lacustrine sediments, the main focus of this project is on the correlation between the sediment stratigraphy and the GPR sub-bottom profiles. Secondary interests are: to estimate the carbon content of a typical small inland lake to help assess how such bodies have contributed to the carbon budget since the last glaciation; and to investigate chemical variability within the sediments. The work in this project includes GPR surveying, sediment coring, and sediment physical, geochemical and chronostratigraphic data acquisition, calibration and correlation. First of all, 50 and 100 MHz GPR surveys were completed on Grassy Pond when the lake surface was frozen in the winter. Bathymetric and depth-to-bedrock maps were created from the GPR profiles. Based on these two maps, a sediment distribution map was also created and this was used to choose sediment coring locations. Four sediment cores were collected by using a rod-driven piston corer, and additional GPR profiles were collected over these core locations. The cores were then scanned by a Multi-Sensor Core Logger (MSCL) to determine the physical properties. After that, the cores were sub-sampled and geochemically analyzed by ICP-OES. Selected sediment samples were also analyzed for C and N contents and isotopes, and radiocarbon dated. Lastly, the linkage was made between the geophysical and geochemical data, and a simple GPR forward model was created based on the sediment physical properties to enhance the data interpretation and correlation. The results show that the lake sediments of Grassy Pond are highly-organic and water-rich. Forward models of EM wave reflections show that the laminated GPR reflections within the sediments are caused by variations in water content. The geochemical analysis shows that the water content is anti-correlated to the lithic elemental concentrations. Since the lithic inputs can reflect past climate changes, we suggest that paleoclimatic changes may ultimately be responsible for the laminations seen in the GPR profiles. The carbon budge of Grassy Pond is calculated based on the sediment volume and average carbon content of the sediments, and it is estimated as 29 kg/m2, which is significantly higher than forest soils. Besides these major results, one of our basal sediment samples is dated back to 8.6 radiocarbon years ago, which corresponds to the end of last glaciation in the same region of Newfoundland. The sediments of Grassy Pond are found to be highly enriched in arsenic (As) and molybdenum (Mo), likely associated with the erosion of iron oxide minerals in the surrounding land, as Grassy Pond overlies the alteration zone of a gold prospect. In the deepest sediment core, many elements show a concentration peak near 6.3k years ago when the regional climate started to become drier, and erosion rates increased.

Download or read book Geological Records of Tsunamis and Other Extreme Waves written by Max Engel and published by Elsevier. This book was released on 2020-07-25 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological Records of Tsunamis and Other Extreme Waves provides a systematic compendium with concise chapters on the concept and history of paleotsunami research, sediment types and sediment sources, field methods, sedimentary and geomorphological characteristics, as well as dating and modeling approaches. By contrasting tsunami deposits with those of competing mechanisms in the coastal zone such as storm waves and surges, and by embedding this field of research into the wider context of tsunami science, the book is also relevant to readers interested in paleotempestology, coastal sedimentary environments, or sea-level changes, and coastal hazard management. The effectiveness of paleotsunami records in coastal hazard-mitigation strategies strongly depends on the appropriate selection of research approaches and methods that are tailored to the site-specific environment and age of the deposits. In addition to summarizing the state-of-the-art in tsunami sedimentology, Geological Records of Tsunamis and Other Extreme Waves guides researchers through establishing an appropriate research design and how to develop reliable records of prehistoric events using field-based and laboratory methods, as well as modeling techniques. Features a comprehensive overview of the state of the art in tsunami sedimentology and paleotsunami research Offers advice on the most appropriate mapping, sampling, and analytical approaches for a wide variety of coastal settings and sedimentary environments Provides methodological details for field sampling and the most important proxy analyses
