Download or read book Sea-Level Rise for the Coasts of California, Oregon, and Washington written by National Research Council and published by National Academies Press. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Process-based morphodynamic modelling is one of the relatively new tools at the disposal of coastal scientists, engineers and managers. On paper, it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice, a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest, it should run long enough and robustly to see the real effects happen, and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next, practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally, translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell, this book provides an in-depth review of ways to model coastal processes, including many hands-on exercises.

Book excerpt: Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.

Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a conceptual roadmap to show how some of the numerous pieces of complex coastal systems intersect and might interact under changing future environmental regimes. It is addressed to a non-technical but environmentally literate audience that includes the lay public, policy makers, planners, engineers and academics interested in the causes and consequences of global changes as they are likely to affect coastal systems. The book also outlines some strategies for anticipating and responding to the challenges that lie ahead. The purpose is not to offer a technical treatise on how to build better numerical models or to provide the cognoscenti with new scientific details or theories. Quite on the contrary the authors aim to provide a holistic, easy-accessible overview of coastal systems and therefore use a writing style that is non-technical, nonmathematical and non-jargonized throughout. Wherever scientific terms are required to avoid ambiguity, a clear and simple definition is presented and those definitions are repeated in the glossary. The authors aim to communicate with all who care about the future of coastal environments. In Part 1, they present some underlying general “big picture” concepts that are applicable to coastal processes and coastal change worldwide. Part 2 reviews some of the more important physical, ecological and societal causes and outcomes of coastal change. A selection of case studies of some prominent and highly vulnerable coastal regions is presented in Part 3. Some strategies for facilitating and supporting collaboration among the global scientific community to enhance future coastal resilience are outlined in Part 4.

Download or read book Salt Marshes written by Duncan M. FitzGerald and published by Cambridge University Press. This book was released on 2021-04-22 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt marshes are highly dynamic and important ecosystems that dampen impacts of coastal storms and are an integral part of tidal wetland systems, which sequester half of all global marine carbon. They are now being threatened due to sea-level rise, decreased sediment influx, and human encroachment. This book provides a comprehensive review of the latest salt marsh science, investigating their functions and how they are responding to stresses through formation of salt pannes and pools, headward erosion of tidal creeks, marsh-edge erosion, ice-fracturing, and ice-rafted sedimentation. Written by experts in marsh ecology, coastal geomorphology, wetland biology, estuarine hydrodynamics, and coastal sedimentation, it provides a multidisciplinary summary of recent advancements in our knowledge of salt marshes. The future of wetlands and potential deterioration of salt marshes is also considered, providing a go-to reference for graduate students and researchers studying these coastal systems, as well as marsh managers and restoration scientists.

Book excerpt: More severe storms and rising seas will inexorably push the American coastline inland with profound impact on communities, infrastructure, and natural systems. In A New Coast, Jeffrey Peterson presents the science behind predictions for coastal impacts and explains how current policies fall short of what's needed to prepare for these changes. He outlines a framework of bold, new national policies and funding to support local and state governments. Peterson calls for engagement of citizens, the private sector, as well as local and national leaders in a "campaign for a new coast." This is a forward-looking volume offering new insights for policymakers, planners, business leaders preparing for the changes coming to America's coast.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Salt marshes are highly productive ecosystems which perform many valuable services including carbon sequestration, nutrient transformation, and mitigation of rough waters generated by storms. Coastal salt marshes currently face threats resulting from global climate change, including sea level rise (SLR). Coastal marshes have kept pace with historical SLR through elevation gain via sediment precipitation from tidal waters. In the coming century, sea level is expected to increase 5x-8x faster than the previous century. Since the rate of sedimentation is unlikely to increase with SLR, marshes are in danger of habitat loss via drowning and subsidence. The decomposing organisms in salt marsh sediments are essential to maintaining marsh plant health. The response of decomposing organisms to longer periods of inundation is unclear. To determine how the prokaryote and invertebrate communities may change in response to SLR, mesocosms were designed, which simulated different inundation intensities within the marsh. A gradient developed over the 10-month sampling period in which the most inundated sediments had significantly different communities than the driest sediments. The high inundation treatments were dominated by anaerobic prokaryotes and insect larvae, and sulfate reduction was the predominant decomposition processes. The ambient mesocosms (driest sediments) were dominated by aerobic prokaryotes and oligochaete worms. Aerobic processes such as leaf litter decay became the key decomposition processes in these sediments.

Available in PDF, EPUB and Kindle. Book excerpt: Coastal salt marshes are under stress from anthropogenic climate change-induced sea level rise (SLR). Sediment microbial decomposition is a major driver of marsh subsidence and any impact of SLR on this biotic process would have a direct effect on marsh surface elevation relative to sea level. Furthermore, sensitivity to SLR of microbial community composition may play a role in the functional response. I collected sediment from six coastal marshes on the United States Atlantic East coast, exposed it to simulated sea level rise and measured total respired carbon over a three week period. My results indicated that SLR caused a decrease in microbial decomposition but that this functional response varied among sites and between elevations within sites. Although differences in decomposition rates among sites were related to organic matter content, differential functional responses to sea-level rise among sites and elevations could not be explained by organic matter, nor a suite of environmental variables that have the potential to effect microbial activity (i.e., porewater pH, salinity and redox potential). In order to determine if changes in community composition might explain the functional response that I observed, I conducted a terminal-restriction fragment length polymorphism analysis of 16S rDNA extracted from sediment from the Massachusetts and New Hampshire sites. I found that microbial community composition varied between the two sites. Furthermore, increased inundation caused a decrease in microbial community compositional shift that corresponded to a decline in decomposition rate. My results suggest that microbial functional response to SLR may be linked to changes in community composition.

Download or read book Climate Change Impacts to the Tidal Salt Marsh Habitats of San Pablo Bay, California written by Karen Maria Thorne and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of ecosystems to climate change is difficult to evaluate and predict, and often are constrained by anthropogenic modifications to the natural environment. Here, I assess the impacts of sea-level rise and extreme storm events on a tidal salt marsh ecosystem located in San Francisco Bay estuary (California, USA) that contains local endemic and endangered wildlife species. The San Francisco Bay estuary has been heavily impacted from human development resulting in the loss of over 80% of its historic tidal salt marshes. In this dissertation, I hypothesize that there will be short-term impacts from extreme storm events and long-term impacts from sea-level rise on the San Pablo Bay endemic marsh wildlife. The first chapter of this dissertation is a discussion about the current state of understanding about climate change impacts on salt marsh habitats and wildlife, using San Pablo Bay National Wildlife Refuge (SPBNWR) as a case study. The second chapter documents two extreme storm events in 2010 and 2011, and discusses impacts on available marsh habitats. At peak storm surge, over 65% (2010) and 93% (2011) of the marsh habitat for wildlife was under water, presumably increasing predation and drowning risk. In the third chapter, I evaluate if SPBNWR is currently keeping pace with sea-level rise and what biogeomorphic processes may be important. Subsidence and accretion was found to vary spatially, with only 37% of the marsh keeping pace with current sea-level rise rates. Surprisingly, I found widespread subsidence (55%) in areas adjacent to constructed levees. Using Akaike Information Criterion (AICc), I found that the distance from the sediment source (San Pablo Bay edge) was the most important covariate to determine accretion. In the fourth chapter, I develop a spatially-explicit, sea-level rise response model for SPBNWR to assess habitat resiliency to 2100. The model projected a loss of most high marsh habitat by 2050, and a loss of most mid marsh habitat by 2040 to 2060. Low marsh habitat showed a temporary increase in area between 2030 and 2050, with the peak (658 ha) in 2040. A large eastern portion of the marsh or 75% of the area (1,004 ha) converted to predominantly mudflat by 2060 with a 47 cm increase in sea-level. However, an almost complete conversion to mudflat occurred with a 75 cm sea-level rise by 2080, with
