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

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

The Polar and Subpolar region comprise one of the seven regions in the world, from the Arctic to the Antarctic, the Atlantic, Pacific, and Indian Oceans. Marine biodiversity in the polar and subpolar regions is one of the richest on earth, hosting important populations of crustaceans, pelagic and benthic species that provide resources for the many seabirds and marine mammals that congregate there. However, these ecosystems, as well as their biodiversity, are vulnerable and already affected by the impacts of climate change and other threats. The high climatic dynamics in those areas have already generated strong modifications to the environment, with irreversible losses in biodiversity and diminished ecosystem services that are essential for the whole planet. The current need to study and understand the biodiversity of the world's oceans makes polar and sub-polar areas key regions for taxonomic and ecological studies.

The effects of human-caused global warming are obvious, requiring new strategies and approaches. The concept of business-as-usual is now no longer beneficial. Extraction of renewable energy in marine environments represents a viable solution and an important path for the future. These huge renewable energy resources in seas and oceans can be harvested, including wind, tide, and waves. Despite the initial difficulties related mostly to the elevated operational risks in the harsh marine environment, newly developed technologies are economically effective or promising. Simultaneously, many challenges remain to be faced. These are the main issues targeted by the present book, which is associated with the Special Issue of Energies Journal entitled “Renewable Energy in Marine Environment”. Papers on innovative technical developments, reviews, case studies, and analytics, as well as assessments, and papers from different disciplines that are relevant to the topic are included. From this perspective, we hope that the results presented are of interest to for scientists and those in related fields such as energy and marine environments, as well as for a wider audience.

Geothermal energy stands out because it can be used as a baseload resource. This book, unlike others, examines the geology related to geothermal applications. Geology dictates (a) how geothermal resources can be found, (b) the nature of the geothermal resource (such as liquid- or vapor-dominated) and (c) how the resource might be developed ultimately (such as flash or binary geothermal plants). The compilation and distillation of geological elements of geothermal systems into a single reference fills a notable gap.

The 4.4-billion-year history of the oceans and their role in Earth's climate system It has often been said that we know more about the moon than we do about our own oceans. In fact, we know a great deal more about the oceans than many people realize. Scientists know that our actions today are shaping the oceans and climate of tomorrow—and that if we continue to act recklessly, the consequences will be dire. Eelco Rohling traces the 4.4-billion-year history of Earth's oceans while also shedding light on the critical role they play in our planet's climate system. This timely and accessible book explores the close interrelationships of the oceans, climate, solid Earth processes, and life, using the context of Earth and ocean history to provide perspective on humankind's impacts on the health and habitability of our planet.

This book brings together the cumulative results of a three-year project focused on the assemblies and administrative systems of Scandinavia, Britain, and the North Atlantic islands in the 1st and 2nd millennia AD. In this volume we integrate a wide range of historical, cartographic, archaeological, field-based, and onomastic data pertaining to early medieval and medieval administrative practices, geographies, and places of assembly in Norway, Sweden, Denmark, Iceland, the Faroe Islands, Scotland, and eastern England. This transnational perspective has enabled a new understanding of the development of power structures in early medieval northern Europe and the maturation of these systems in later centuries under royal control. In a series of richly illustrated chapters, we explore the emergence and development of mechanisms for consensus. We begin with a historiographical exploration of assembly research that sets the intellectual agenda for the chapters that follow. We then examine the emergence and development of the thing in Scandinavia and its export to the lands colonised by the Norse. We consider more broadly how assembly practices may have developed at a local level, yet played a significant role in the consolidation, and at times regulation, of elite power structures. Presenting a fresh perspective on the agency and power of the thing and cognate types of local and regional assembly, this interdisciplinary volume provides an invaluable, in-depth insight into the people, places, laws, and consensual structures that shaped the early medieval and medieval kingdoms of northern Europe.
