Historically, submarine-mass failures or mass-transport deposits have been a focus of increasingly intense investigation by academic institutions particularly during the last decade, though they received much less attention by geoscientists in the energy industry. With recent interest in expanding petroleum exploration and production into deeper water-depths globally and more widespread availability of high-quality data sets, mass-transport deposits are now recognized as a major component of most deep-water settings. This recognition has lead to the realization that many aspects of these deposits are still unknown or poorly understood. This volume contains twenty-three papers that address a number of topics critical to further understanding mass-transport deposits. These topics include general overviews of these deposits, depositional settings on the seafloor and in the near-subsurface interval, geohazard concerns, descriptive outcrops, integrated outcrop and seismic data/seismic forward modeling, petroleum reservoirs, and case studies on several associated topics. This volume will appeal to a broad cross section of geoscientists and geotechnical engineers, who are interested in this rapidly expanding field. The selection of papers in this volume reflects a growing trend towards a more diverse blend of disciplines and topics, covered in the study of mass-transport deposits.

This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs. - Promotes pragmatic interpretation of deep-water sands using alternative possibilities - Validates the economic importance of SMTDs and BCRS in deep-water exploration and production - Rich in empirical data and timely new perspectives

As with most shorelines around the world, New Jersey beaches are slowly, but inexorably, being eroded, threatening coastal structures and development. In some years more sand is deposited than removed, but all of the state's monitoring devices show that sea level is gradually rising and pushing the New Jersey shoreline inland. The shore is a valuable resource, and its natural, cultural, and economic attractions draw a multitude of permanent and temporary residents each year, extending housing and commercial development onto areas that were once swampland. Not surprisingly, development at the water's edge has been accompanied by an increasing exposure to the natural hazards of the coastal zone--erosion, flooding, and wind damage. In this book, Norbert Psuty and Douglas Ofiara incorporate perspectives from the areas of coastal sciences, economics, public policy, and land-use planning in creating a systematic plan for coastal management and protection. It has been more than a decade since New Jersey developed the nation's first state shore protection plan, and this volume provides a timely evaluation of its achievements and future challenges. This self-contained book provides all of the relevant theories, models, and examples so the reader will not need to refer to any other literature to gain an understanding of the issues and policies surrounding shore protection. It is the authoritative handbook for practitioners and policy makers in many fields, including coastal science and management and engineering, as well as public policy and economics.

This book represents the efforts of over a hundred individuals who planned and executed the NSTS field experiments, analyzed the billions of data points, and distilled their findings and insights into the summaries found here. Because these experiments were of a scope that will seldom, if ever, be duplicated, and because the program brought together many of the foremost field experimentalists in this country, we all felt from the beginning that it was important to preserve the outcome. This was done in two ways. First, the raw data were made available to any interested investigator within 18 months of the completion of each experiment. Secondly, both the methodology of the experiments and the findings from them were codified in the form of a monograph. This book is that result. I have had the occasion recently (Sediments '87 Proceedings, Vol. 1, pp. 642-651) to assess the NSTS performance. I found that we made giant strides in our understanding of the surf zone hydrodynamics --far more than our fondest expectations at the beginning. We were able to do less than we had hoped about the response of the sediment, largely because of a limited ability to measure it at a point. As I reported in the Sediments '87 assessment, we established a new state of the art in measurement techniques and we demonstrated the effectiveness of large, multi-investigator, instrument-intensive experiments for studying nearshore processes.

Mass Transport, Gravity Flows, and Bottom Currents: Downslope and Alongslope Processes and Deposits focuses solely on important downslope and alongslope processes. The book provides clear definitions and characteristics based on soil mechanics, fluid mechanics and sediment concentration by volume. It addresses Slides, Slumps, and Debris Flows, Grain Flows, Liquefied/Fluidized Flows, and Turbidity Currents, Density plumes, Hyperpycnal Flows, the Triggering Mechanisms of Downslope Processes, Bottom Currents, and Soft-Sediment Deformation Structures. The mechanics of each process are described in detail and used to provide empirically-driven categories to help recognize these deposits it the rock record. Case studies clearly illustrate of the problems inherent in recognizing these processes in the rock record, and potential solutions are provided alongside future avenues of research. An appendix also provides step-by-step guidance in describing and interpreting sediments. - Comprehensively addresses modern downslope and alongslope processes, including definitions and mechanisms - Provides key criteria for the recognition of depositional facies in the rock record - Includes case studies to illustrate each downslope and alongslope process - Identifies key problems and potential solutions for future research - Uses pragmatic, empirical, data-driven interpretations to revise conventional facies models
