Book excerpt: The combination of remote sensing and ground truth has proven itself especially useful for scientific investigation within the last few decades. Using this approach, this research has investigated ground subsidence and sea-level rise occurring along the northern shore of the Gulf of Mexico. Specifically, this was focused over the areas of Houston and Galveston, Texas and New Orleans, Louisiana. Supporting this investigation were five methods: Interferometric Synthetic Aperture Radar (InSAR), radar altimetry, the Global Positioning System (GPS), tide gauges, and extensometers. Measurements derived from these methods allowed for the creation of velocity maps and local time series spanning the area of interest. This investigation produced the following products: Twelve (12) 4-pass interferometric-derived velocity maps constructed from raw ERS-1, ERS-2, and Envisat data spanning the years between 1992 and 2012. Twenty-five (25) sea-level anomaly time series from Topex-Poseidon (T/P) and Jason-1 Geophysical Data Records (GDRs) for assessment of absolute sea level change throughout the northern Gulf of Mexico spanning the years between 1992 and 2012. Twenty-eight (28) GPS stations observational data processed for secular trend analysis. Twenty-two (22) tide gauges stations monthly mean sea-level (MSL) records were obtained for secular trend and Fourier analysis. Seven (7) extensometers near Galveston Bay recorded compaction data which was then utilized for secular trend analysis. Results provided by radar altimetry found multidecadal variability (1992-2012) within expected norms with average rates of absolute sea-level rise bounded between 3 and 4 mm yr-1 within the northern Gulf of Mexico. Therefore, for those regions undergoing high rates of relative sea level rise, the majority is attributed to subsidence. The regions of Houston and Galveston were generally found to be stable. However, Seabrook (on the west side of Galveston Bay) and regions near the inlet of the Houston ship channel (Baytown and Channel View) require continued monitoring due to recent rates of subsidence higher than the surrounding areas and regional norms. The city of New Orleans was found to be stable and experiencing subcentimeter subsidence rates. Areas to the southwest of New Orleans (Houma, New Iberia, Morgan City, and Raceland) and near the peninsula tip were consistently detected by both ground truth and InSAR to be subsiding at rates in excess of 30 mm yr-1. Spatial correlation of the velocity profiles with tectonic and anthropogenic factors allows inferences to be made in regards to the underlying causation mechanism(s).

Available in PDF, EPUB and Kindle. Book excerpt: A must-read for Gulf Coast scientists, naturalists, and residents . . . From Florida to Mexico and along the shores of Cuba, the coasts of the Gulf of Mexico are vulnerable to sea-level rise because of their fragile and low-lying shorelines and adjacent coastal environments. In addition to wetlands, river deltas, beaches, and barrier islands, millions of people who live and work along the Gulf coast are susceptible to the affects of both intense storms in the short term and a gradual rise in sea level over the longer term. While global warming headlines any current discussion of this topic and is certainly a major factor in sea-level change, it is not the only factor. Earthquakes and other crustal shifts, the El Niño/La Niña phenomena, river impoundment and sedimentation, tides, and weather can all affect local, regional, and global sea levels. In Sea-Level Change in the Gulf of Mexico, Richard A. Davis Jr. looks at the various causes and effects of rising and falling sea levels in the Gulf of Mexico, beginning with the Gulf’s geological birth over 100 million years ago, and focusing on the last 20,000 years, when global sea levels began rising as the glaciers of the last major ice age melted. Davis reviews the current situation, especially regarding beach erosion and loss of wetlands, and offers a preview of the future, when the Gulf Coast will change markedly as the twenty-first century progresses. Amply illustrated and written in a clear, straightforward style, Sea-Level Change in the Gulf of Mexico is a valuable resource for anyone who cares deeply about understanding the past, present, and future of life along the coast of the Gulf of Mexico.

This book was released on 2012-12-06 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.

This book was released on 2010 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A coastal vulnerability index (CVI) was used to map the relative vulnerability of the coast to future sea-level rise along the Northern Gulf of Mexico from Galveston, TX, to Panama City, FL. The CVI ranks the following in terms of their physical contribution to sea-level rise-related coastal change: geomorphology, regional coastal slope, rate of relative sea-level rise, historical shoreline change rate, mean tidal range, and mean significant wave height. The rankings for each variable are combined and an index value is calculated for 1-kilometer grid cells along the coast. The CVI highlights those regions where the physical effects of sea-level rise might be the greatest. The CVI assessment presented here builds on an earlier assessment conducted for the Gulf of Mexico. Recent higher resolution shoreline change, land loss, elevation, and subsidence data provide the foundation for a better assessment for the Northern Gulf of Mexico. The areas along the Northern Gulf of Mexico that are likely to be most vulnerable to sea-level rise are parts of the Louisiana Chenier Plain, Teche-Vermillion Basin, and the Mississippi barrier islands, as well as most of the Terrebonne and Barataria Bay region and the Chandeleur Islands. These very high vulnerability areas have the highest rates of relative sea-level rise and the highest rates of shoreline change or land area loss. The information provided by coastal vulnerability assessments can be used in long-term coastal management and policy decision making."--Page 1.

This book was released on 2012-12-06 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in sea level caused by global warming can be disastrous to modern civilization. Therefore, it is important to use accurate and reliable methods to monitor any change. During this century, and, in particular, the last three decades, tide-gauge records have been used to show these changes related to the world's oceans. Aubrey and Emery suggest, however, that tidal gauges should not be used unquestioningly as a benchmark for measuring eustatic sea-level changes. Tectonism, subsidence, ocean current variability, and human activity can, and do, affect the accuracy of these records. Understanding the reasons for changes in land and sea levels is essential for the proper development of coastal regions. The results of this study provide guiding data for scientific, engineering, and policy solutions to coastal flooding. Determining the true causes of relative subsidence, and how to use geological and oceanological controls, will allow us to exist within our natural environment, rather than force nature to conform to our legal and temporary 'remedies.'

This book was released on 2013-03-09 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse-induced climate warming increasingly appears to be a reality, and the warming climate will be accompanied by an accelerated sea level rise - as much as 60-100 cm over the next century. What is commonly absent in the discussion of rising sea level, however, is the role played by the subsidence of low-lying coastal areas, which can have a far greater local effect than the eustatic rise of the sea. The combined sea-level rise and land subsidence will almost certainly make the greatest impact on coastal societies in the densely populated regions of southern Asia, but its effects will be felt globally. This volume explores the concepts of sea-level rise and coastal subsidence, both natural and anthropogenically accelerated, in the form of a series of case studies in such diverse locations as Bangkok, Bangladesh, Venice, and the Niger and Mississippi deltas, as well as a discussion of the economic, engineering and policy responses that must be considered if the effects of local sea-level rise are to be mitigated.

This book was released on 2008-01-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main impacts of global warming is accelerated sea-level rise: Intergovernmental Panel on Climate Change predictions suggest that the rate of rise could reach as high as 5'10 mm/yr by the end of this century. While it is generally recognized that accelerated sea-level rise will severely impact low-gradient coastlines, scientists are still ill prepared to predict coastal response. A study of seven Gulf Coast estuaries (Mobile Bay and Mississippi Sound, Weeks Bay, Calcasieu Lake, Sabine Lake, Galveston Bay, Matagorda Bay, and Corpus Christi Bay) was aimed at examining their response to past changes in the rate of sea-level rise and climate. The rates of change are of the same magnitude as those predicted for this century. The estuarine response to change has been one of abrupt landward retreat and major reorganization of estuarine environments at decadal time scales. This book should be of interest to scientists and policy makers concerned with future impacts of global warming.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is having an increasing impact on coastal, estuarine, and marine environments worldwide. This book provides state-of-the-art coverage of climate change effects on estuarine ecosystems from local, regional, and global perspectives. With editors among the most noted international scholars in coastal ecology and estuarine science and contributors who are world-class in their fields, the chapters in this volume consist of comprehensive studies in coastal, estuarine and marine sciences, climate change, and coastal management and provide an extensive international collection of data in tabular, illustrated, and narrative formats useful for coastal scientists, planners, and managers. Comprised of three sections: (1) physical-chemical aspects; (2) biological aspects; and (3) management aspects, the book not only examines climatic and non-climatic drivers of change affecting coastal, estuarine, and marine environments but also their interactions and effects on populations of organisms, communities, habitats, and ecosystem structure and function. Pulling together today’s most salient issues and key literature advances for those concerned with coastal management, it allows the reader to see across direct and indirect interactions among disciplinary and ecosystem boundaries. Climate Change and Estuaries meets the research needs of climate scientists, estuarine and marine biologists, marine chemists, marine geologists, hydrologists, and coastal engineers, while students, professors, administrators, and other professionals will also find it an exhaustive reference.

Book excerpt: Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.
