Available in PDF, EPUB and Kindle. Book excerpt: Future sea-level rise will dramatically affect coastal landscapes and populations. The coast of North Carolina (USA) is particularly vulnerable to sea-level rise because its low-lying coastal plain is expansive, has a low gradient, provides significant ecosystem services and is economically important. In order to understand how future sea-level rise may affect the coast, it is necessary to study past sea-level rise. Widespread salt-marshes compose much of North Carolina's coastal system, providing an excellent environment from which to produce relative sea-level reconstructions using salt-marsh foraminifera, whose distribution is controlled by tidal elevation. Distinctive assemblage zones related to different tidal ranges can be recognized in salt-marsh foraminiferal assemblages, allowing them to be used as a proxy for reconstructing sea level as sea-level indicators. Foraminiferal assemblages from surface samples along two transects at Sand Hill Point on Cedar Island, North Carolina added to an existing modern training set of paired observations of foraminiferal assemblages and tidal elevation; these data provide local analogues for interpreting fossil assemblages using a locally weighted-weighted average (LWWA) regression model. Foraminiferal assemblages preserved in a radiocarbon-dated core of salt-marsh peat from Sand Hill Point were used to produce a continuous, high-resolution late Holocene relative sea-level reconstruction. The existing late Holocene RSL reconstruction from North Carolina is based on two sites: Sand Point on Roanoke Island and Tump Point on Cedar Island. The Sand Point record spans the last ~2200 years, but the Tump Point record spans only the last ~1000 years. Therefore, the sea-level history described from 200 BC to 1000 AD is based on only one site. The new sea-level reconstruction from Sand Hill Point extends the existing record from nearby Tump Point, NC by 1400 years, producing a high resolution, continuous record of sea-level change spanning 1500 BC - 1915 AD. This new record tests whether patterns and rates of late Holocene sea-level changes reconstructed elsewhere in North Carolina are consistent throughout the region. The calculated average rate of relative sea-level rise for Sand Hill Point of 0.7 mm/year is consistent with patterns of regional rates along the US Atlantic coast, which may be partly attributed to isostatic response to deglaciation of the Laurentide Ice Sheet.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "A joy to read from two of the most prominent geologists who have worked for the better part of their careers in the Florida Keys. Places important environmental focus on modern-day issues facing the island ecosystems, the health of Florida Bay, the nearshore areas, and ultimately the reef tract."--Donald F. McNeill, University of Miami "A compelling narrative that weaves fascinating historical personalities and periods with the geological characteristics of the Florida Keys into a colorful tapestry. A fun, interesting, and informative read!"--Eugene C. Rankey, University of Kansas Two world-class geologists draw on their prolific fifty-year careers in this comprehensive guide to the geology and biology of the Florida Keys and Florida Bay. Eugene Shinn and Barbara Lidz dive into the past, present, and future of an area that has long been a natural laboratory for learning about coral reef formation and the origins of limestone. They explain how underlying Pleistocene topography controls the shapes of today's coral reefs, how sea-level rise created Florida Bay, and how hurricanes mold limemud banks and strip vegetation from the Florida Keys. They discuss the recent decline of coral reefs due to overpopulation, pollution, climate change, and other factors. An itinerary is included for a hands-on three-day field trip, guiding visitors to the best places to see the famous reef formations and geologic processes of the Keys. As glaciers continue to melt and reform at Earth's poles, sea level is currently rising and will fall again at some point in the geologic future. In this volume, Shinn and Lidz demonstrate the value of the Keys and immediate surroundings as an environmental laboratory to study past effects of sea-level change and to stimulate ideas for further research.

Download or read book Sea Level Change written by National Research Council and published by National Academies Press. This book was released on 1990-02-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea-level rise may be one of the consequences of global warming. To understand changes in sea level caused by the "greenhouse effect," we must understand the factors that have caused the sea level to fluctuate significantly throughout history. This new volume explores current views among scientists on the causes and mechanisms of sea-level change. The authors examine measurement programs and make recommendations aimed at improving our understanding of the factors that affect sea level. It will be welcomed by scientists, engineers, and policymakers concerned about "greenhouse" issues and sea-level change, the environmental community, researchers, and students.

This book was released on 2013-12-20 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: An editorial by Wanless (1982), entitled "Sea level is rising - so what?", tells the case of an executive editor of a major city newspaper, who, when confronted with evi dence for a recent sea-level rise, replied: "That just means the ocean is six inches deeper, doesn't it?". Whether his "so what?" attitude was real or put on to dike a threat of sensation, there is at present a wide and deepening interest in ongoing and future global sea-level change. This interest has grown along with the concern over global warming due to increasing levels of C02 and trace gases. A stage has been reached where investigators of climat- sea-level relationships call for long-term measurement programmes for ice-volume changes (using satellite altimetry) and changes in temperature and salinity of the oceans (ther mal expansion). This manual, however, is primarily concerned with sea level changes in the past, mainly since the end of the last glaciation. Its major objective is to help answer the ques tion: "how?", which, of course, is little else but to assist in the gathering of fuel for the burning question: "why?" Good fuel, hopefully, for the less smoke and ashes, and the more heat and light produced by that fire, the better scientists are enabled to develop a quantitative under standing of past, and hence of future, sea-level changes on different spatial and temporal scales.
Download or read book Reconstruction of Late Holocene Precipitation for Central Florida as Derived from Isotopes in Speleothems written by Limaris R. Soto and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Little is known about the paleo-precipitation of the Florida Peninsula. In order to better understand Floridas late Holocene climate variability (last 4,200 years), the isotopic composition was analyzed of four speleothems from two caves, in West-Central Florida. Two speleothems were collected from BRC Cave in Hernando County, and two others from Briar Cave in Marion County. This study represents the first speleothem-based paleoclimate records for Florida. Uranium-series disequilibrium analyses were determined by using thermal ionization mass spectrometry (TIMS) to provide accurate determination of chronology of the deposition of the speleothems.
Download or read book Wet Site Archaeology written by Barbara A. Purdy and published by CRC Press. This book was released on 2018-01-10 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the result of an International Conference on Wet Site Archaeology funded by the National Endowment for the Humanities, explores the rewards and responsibilities of recovering unique assemblages from water-saturated deposits. Characteristics common to all archaeological wet sites are identified from Newfoundland to Chile, Polynesia to Florida, and from the Late Pleistocene to the Twentieth Century. Topics include innovative excavation and preservation methods; the need for adequate funding to preserve and analyze the abundant biological and cultural remains recovered only at archaeological wet sites; expanded knowledge of past environments, subsistence, technologies, artistic expressions, skeletal structure, and pathologies; the urgency to inform developers and governmental bodies about the invisible heritage entombed in wetlands that is often destroyed before it can be investigated; a formula for establishing priorities for excavating wet sites; and how to determine when enough of a wet site has been sampled.Many famous sites and discoveries are described in this volume, including Herculaneum, Hoko River, Hontoon Island, Key Marco, Monte Verde, Ozette, Somerset Levels, Windover, bog bodies of Northern Europe, and lake dwellers of Switzerland. Professional and amateur archaeologists, as well as anyone interested in archaeology or the significance of wet site archaeology will find this book fascinating.

This book was released on 2007-01-05 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from Congress, Surface Temperature Reconstructions for the Last 2,000 Years assesses the state of scientific efforts to reconstruct surface temperature records for Earth during approximately the last 2,000 years and the implications of these efforts for our understanding of global climate change. Because widespread, reliable temperature records are available only for the last 150 years, scientists estimate temperatures in the more distant past by analyzing "proxy evidence," which includes tree rings, corals, ocean and lake sediments, cave deposits, ice cores, boreholes, and glaciers. Starting in the late 1990s, scientists began using sophisticated methods to combine proxy evidence from many different locations in an effort to estimate surface temperature changes during the last few hundred to few thousand years. This book is an important resource in helping to understand the intricacies of global climate change.
