Book Sandy Beach Morphodynamics

Download or read book Sandy Beach Morphodynamics written by Derek Jackson and published by Elsevier. This book was released on 2020-05-19 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sandy beaches represent some of the most dynamic environments on Earth and examining their morphodynamic behaviour over different temporal and spatial scales is challenging, relying on multidisciplinary approaches and techniques. Sandy Beach Morphodynamics brings together the latest research on beach systems and their morphodynamics and the ways in which they are studied in 29 chapters that review the full spectrum of beach morphodynamics. The chapters are written by leading experts in the field and provide introductory level understanding of physical processes and resulting landforms, along with more advanced discussions. Includes chapters that are written by the world’s leading experts, including the latest up-to-date thinking on a variety of subject areas Covers state-of-the-art techniques, bringing the reader the latest technologies/methods being used to understand beach systems Presents a clear-and-concise description of processes and techniques that enables a clear understanding of coastal processes

Book Paleotempestology and Depositional History of Clear Pond San Salvador Island Bahamas

Download or read book Paleotempestology and Depositional History of Clear Pond San Salvador Island Bahamas written by Mark R. Dalman and published by . This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The field of paleotempestology has gained more awareness in the past decade as a result of increased hurricane intensity, quantity, and duration within the late Holocene. One of the best localities to find records of hurricane overwash deposits is in the Bahamian islands. San Salvador Island, Bahamas (SSI) is a small (150km2), isolated carbonate platform, that contains shallow (0.5-3m) saline lakes that occur in between interdune areas of arcuate dune ridges. Due to San Salvador Island's location within the Bahamian archipelago and the Atlantic Ocean, the island is poised to record hurricane strikes and the record of these events can be found in coastal lakes. Clear Pond is a shallow (~1m), variably saline (16-30 ppt) lake in the southwestern edge of the island, that is separated from the Atlantic Ocean by Holocene dunes. It was a previously uncharacterized pond, but like many other depositional environments on San Salvador, it is constantly recording climatic and anthropogenic changes on the island. This study addresses the following questions: 1) Is there a seasonal salinity variation within the pond and what is the general limnology of the pond, 2) Can we identify large storm events in the sedimentary record of Clear Pond, and 3) What is the depositional history for Clear Pond for the past 4000 years? Nine sediment cores, ranging in length from 50 to 150 cm, were recovered from Clear Pond. The cores were analyzed for organic and carbonate content, dry bulk density, grain size, sediment fabric, and mollusk and ostracode composition. Additionally, x-ray fluorescence, spectrophotometry, and x-radiography were carried out on sediment cores. Salinity varied from brackish conditions in the summer and fall to more marine during the winter and spring seasons. It was also influenced by a previously uncharacterized karst conduit. Large storm events were identified through an increase in grain size and dry bulk density, and additionally by x-radiographs. A catastrophic hurricane recurrence interval of 478 years and an annual landfall probability of 0.21% were found as well. The record of Clear Pond indicates an average sedimentation rate of 2.3 cm/ 100 years which suggests the record recovered is at least 5200 years old. These cores record a major climatic shift occurring at 1460 ybp which correlates with the end of a documented Caribbean dryness period. The facies shift is from a sand and mud laminated facies to a recent, massive bioturbated facies. The record documents multiple hurricane strikes from 1600-3400 ybp which supports a hurricane 'hyperactivity period' from 1000- 3000 ybp from other areas in the Atlantic and Gulf of Mexico. These large storm events are linked to two large-scale climate mechanisms, the location of the Bermuda high and the strength of the North Atlantic Oscillation. The ability to characterize and identify past overwash deposits in the Bahamas may be useful in climate reconstruction and landfall probability assessments. These results are the first proxy records for hurricane strikes on the west coast of San Salvador Island."--Abstract.

Book Pleistocene and Holocene Carbonate Environments on San Salvador Island Bahamas

Download or read book Pleistocene and Holocene Carbonate Environments on San Salvador Island Bahamas written by H. Allen Curran and published by American Geophysical Union. This book was released on 1991-01-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 175. Although isolated and small in size, San Salvador Island is in many ways a unique place—an all carbonates setting on a small, tectonically stable platform, surrounded by deep oceanic waters, and an historical footnote as the widely accepted first landing site of Christopher Columbus in the New World in 1492. Columbus' stay here was brief, and the major events of subsequent history largely have passed San Salvador by. This is not a tourist island; the natural beauty, floras, and faunas of the Bahamas are well preserved here. The overview theme of this series of field excursions on San Salvador will be interpretation of paleodepositional environments for the well-exposed Pleistocene and Holocene carbonate rocks that cap the island and recognition of modem analogues from the varied carbonate environments found on the island and its surrounding shelf. Questions of sea level history, diagenetic change, and the surficial processes operating on carbonate island terranes also will be considered. Our trip will begin with a low-attitude overflight to view features of the main Bahama platform enroute to San Salvador, which lies just beyond the eastern edge of the platform.

Book The Proceedings of the Coastal Sediments 2011

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings contains nearly 200 papers on cutting-edge research presented at the seventh international Symposium on Coastal Engineering and Science of Coastal Sediment Processes, held May 2OCo6, 2011, in Miami, Florida, USA. This technical specialty conference was devoted to promoting an interdisciplinary exchange of state-of-the-art knowledge among researchers in the fields of coastal engineering, geology, oceanography, and related disciplines, with a theme of bringing together theory and practice. Focusing on the physical aspects of sediment processes in various coastal environments, this three-volume conference proceedings provides findings from the latest research and newest engineering applications. Session topics cover a wide range including barrier-island morphodynamics and evolution, beach nourishment and shore protection, coastal dunes, cohesive sediment transport, field and laboratory measurements of sediment transport processes and numerical modeling, gravel transport, large-scale and long-term coastal changes, LiDAR and remote sensing, longshore and cross-shore sediment transport, marsh and wetlands, regional sediment management, river deltas, sea-level changes, shelf and sand bodies, shoreline changes, tidal inlets and navigation channels. A special session on recent research findings at the Northern Gulf of Mexico is also included."
