Available in PDF, EPUB and Kindle. Book excerpt: Continental margins form the relatively narrow transition zones between the different domains of land masses and deep-ocean basins. They are the main regions of sediment input and transfer of sediments to the oceans and thus represent important zones of sediment flux. This work addresses three topics of significance to continental margin development: sedimentation, mass-wasting and stability. It should be of interest to marine geologists, sedimentologists, palaeoceanographers and physical properties specialists.

This book was released on 2001 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The areas visited during the 10th Training-through-Research Programme were the Portuguese Margin, the Gulf of Cadiz, the Lucky Strike area of the Mid-Atlantic Ridge, the Rockall Trough, the Southern Faeroe margin, and the Varring Plateau (Norwegian margin). The investigations were aimed atstudying such geological processes as neotectonics, fluid migration and escape, sediment processes in canyons and sediment reworking and benthic biology in areas swept by deep-sea bottom currents as well as hydrothermal manifestations on mid-ocean ridges. A seismic and sidescan survey of the Marques de Pombal structure (Portuguese margin) allowed a better understanding of a fault system known here from previous studies such as the ARRIFAN0 and BIGSET projects. The fault pattern has been mapped and acoustic images have helped to evaluate the status of their activity. The Marques de Pombal structure showed little evidence of recent activity and is being covered by sediments. Shallow slides found in the vicinity of the structure may, however, indicate some occasional activity disturbing the overlying sedimentary cover. The Pereira de Sousa fault was found to be much more active. Six new mud volcanoes were discovered and studied in the Gulf of Cadiz. Most of them were proved to be recently active. The mud volcanism of the Gulf of Cadiz can be considered as two characteristic regions with different mud breccia lithological composition. Several types of lava sulphite ores sampled during the Azores campaign of Leg 2 allowed a better understanding of volcanic evolution and associated processes of this area. A short 3.5 kHz survey across the Porcupine Seabight mouth, combined with existing swath bathymetry data and a few cores from the area, confirmed the findings of the TTR-7 cruise that the Gollum channel system is currently inactive. The study of a canyon on the northeastern Rockall Trough margin showed that the system is inactive at the present time and the last pulse of active downslope sediment transport took place in immediate pre-Holocene time. Debris flows were found mostly on the flanks of the canyon while the axial zone showed numerous signs of erosion. Sand was not particularly common in the studied area. It is suggested that significant amounts of sand are trapped in the canyon head, possibly due to slumps blocking the narrower waist area. Abundant traces of seabed erosion found immediately beyond the canyon mouth indicate that this area is a bypass zone and sand deposition may occur further into the canyon mouth indicate that this area is a bypass zone and sand deposition may occur further into the basin plain. An extensive collection of TV-guided grab samples and seafloor video records, obtained from sites in the Northern Rockall Trough, Wyville-Thomson Ridge and Southern Faeroe Plateau, provided GOOd insight on the distribution of bottom fauna, including deep-water corals, and of coarse glaciagenie debris. New data on a BSR distribution pattern were obtained on the southeastern part of the Verring Plateau and they suggest that the formation of the Storegga Slide was not directly related to the dissolution of gas hydrates. The investigation also provided a new insight into gas hydrate formation and distribution in the area.

This book was released on 2012-12-06 with total page 1063 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion of interest, effort, and information about the ocean since about 1950 has produced many thousand scientific articles and many hun dred books. In fact, the outpouring has been so large that authors have been unable to read much of what has been published, so they have tended to concentrate their own work within smaller and smaller subfields of oceanog raphy. Summaries of information published in books have taken two main paths. One is the grouping of separately authored chapters into symposia type books, with their inevitable overlaps and gaps between chapters. The other is production of lightly researched books containing drawings and tables from previous pUblications, with due credit given but showing assem bly-line writing with little penetration of the unknown. Only a few books have combined new and previous data and thoughts into new maps and syntheses that relate the contributions of observed biological, chemical, geological, and physical processes to solve broad problems associated with the shape, composition, and history of the oceans. Such a broad synthesis is the objective of this book, in which we tried to bring together many of the pieces of research that were deemed to be of manageable size by their originators. The composite may form a sort of plateau above which later studies can rise, possibly benefited by our assem bly of data in the form of new maps and figures.

Available in PDF, EPUB and Kindle. Book excerpt: The NAG-TEC project was a collaborative effort by the British Geological Survey, the Geological Survey of Denmark and Greenland, the Geological Survey of Ireland, the Geological Survey of the Netherlands, the Geological Survey of Northern Ireland, the Geological Survey of Norway, Iceland GeoSurvey and the Faroese Geological Survey (Jarðfeingi), along with a number of academic partners and significant support from industry. The main focus was to investigate the tectonic evolution of the region with a particular emphasis on basin evolution along conjugate margins. A key outcome was the development of a new tectonostratigraphic atlas and database that includes comprehensive geological and geophysical information relevant for understanding the Devonian to present evolution of the NE Atlantic margins. These provide the foundation upon which ongoing research and exploration of the area can build. This Special Publication provides some of the first scientific results and analysis based on the project, including regional stratigraphic analysis and correlations, crustal structure and interpretation of geophysical data sets, plate kinematics and the evolution of igneous provinces.

Download or read book European Margin Sediment Dynamics written by Jürgen Mienert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides acoustic images about sedimentary systems of the shelf edge, slope and deep-sea-floor. Data obtained by the European North Atlantic Margin and the STEAM Project shows areas of potential instability and deepwater sediment transport systems on the continental slope. The knowledge gained can be used by both academia and hydrocarbon industry so as to arrive at a better understanding of continental margins and the processes shaping them. It will also interest colleagues in earth sciences involved in margin surveys for environmental studies. The current global trend in marine resource development is to move into deeper water, and this book can provide examples relevant to other passive margins around the world. There is a growing need for reliable measurements in deep water and knowledge related to stabilisation. Slope stability problems will be identified with greater reliability, thus improving safety standards for coastal and offshore environmental policies.
