Publisher: American Geophysical Union
ISBN: 0875900453
Category: Science
Page: 417
View: 7214
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 88. This volume focuses on the volcanic, fluid, sedimentary, and tectonic processes occurring in the trencharc-backarc systems of the western Pacific—a natural regional focus for studies of these themes. The results of ocean drilling and associated site surveys in the western Pacific have brought fundamental changes to our understanding of volcanism, crustal deformation, fluid circulation, and sedimentation in active margins and marginal basins. Our goal here is to synthesize the results of ocean drilling in a multi-disciplinary manner, including a comparison of the findings from drilling legs having similar themes, and to emphasize the significance of these results to the broader geoscience community.

An ideal resource for civil engineers working with offshore structures, pipelines, dredging, and coastal erosion, Seafloor Processes and Geotechnology bridges the gap between the standard soil mechanics curriculum of civil engineering and published material on marine geotechnology. Utilizing organized information on sediments and foundations for marine applications from a variety of sources, it provides practical reference information and approaches for analysis and design. This book provides an understanding of the processes and loadings affecting the sediment/water interface and the sediment column on the continental shelf and slope as well as the abyssal plains.

Effects of Trawling and Dredging on Seafloor Habitat


Author: National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Committee on Ecosystem Effects of Fishing: Phase 1 -- Effects of Bottom Trawling on Seafloor Habitats
Publisher: National Academies Press
ISBN: 9780309169806
Category: Science
Page: 136
View: 4967
Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear--specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long--lived species are more vulnerable to towed fishing gear than short--lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries -- the first time that such data has been assembled and analyzed for the entire nation.

Measuring Ocean Currents

Tools, Technologies, and Data
Author: Antony Joseph
Publisher: Newnes
ISBN: 0123914280
Category: Science
Page: 448
View: 1283
Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements. Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials—as well as environmentally hazardous materials—from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection. Coverage of measurement, mapping and profiling techniques Descriptions of technologies for remote measurement of ocean currents and their signatures Reviews crucial aspects of ocean currents, including special emphasis on the planet-spanning thermohaline circulation, known as the ocean's "conveyor belt," and its crucial role in climate change

The Integrated Ocean Drilling Program (IODP: 2000-2013) has provided crucial records of past and present processes and interactions within and between the biosphere, cryosphere, atmosphere, hydrosphere and geosphere. Research in IODP encompasses a wide range of fundamental and applied issues that affect society, such as global climate change, biodiversity, the origin of life, natural hazards involving the study of earthquakes processes, and the internal structure and dynamics of our planet. This compilation of major findings from the 2003-2013/14 phase of IODP, focusing on scientific results rather than description of data acquisition and early inferences, provides invaluable information. Anyone wondering what scientific drilling can achieve will gain quick understanding of the range of questions that are uniquely addressed with this methodology and the ways these data dovetail with other regional information. The excitement of breakthrough findings that occasionally accompanies a drilling project will be evident. IODP obtained unique records from the global ocean basins during the 2003-2013 program phase. This book highlights findings in three theme areas: Subseafloor life and the marine biosphere; Earth's changing environments; and Dynamics of the solid Earth. Each core or borehole log provides a window revealing insights that no other data achieve.

As the importance of the oceans to society grows, so does the need to understand their variation on many temporal and spatial scales. This need to understand ocean change is compelling scientists to move beyond traditional expeditionary modes of investigation. Observing systems will enable the study of processes in the ocean basins over varying timescales and spatial scales, providing the scientific basis for addressing important societal concerns such as climate change, natural hazards, and the health and viability of living and non-living resources along our coasts and in the open ocean. The book evaluates the scientific and technical readiness to move ahead with the establishment of a research-driven ocean observatory network, and highlights outstanding issues. These issues include the status of planning and development, factors that affect the timing of construction and installation, the cost and requirements for maintenance and operations, needs for sensor development and data management, the impact on availability of ships and deep submergence facilities, and the role of research-based observatories within national and international operational ocean observing systems being developed and implemented.
