This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.
Download or read book Impact of Climate Changes on Marine Environments written by Tymon Zielinski and published by Springer. This book was released on 2015-01-28 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the current discussion on global environmental changes by discussing modifications in marine ecosystems related to global climate changes. In marine ecosystems, rising atmospheric CO2 and climate changes are associated with shifts in temperature, circulation, stratification, nutrient input, oxygen concentration and ocean acidification, which have significant biological effects on a regional and global scale. Knowing how these changes affect the distribution and abundance of plankton in the ocean currents is crucial to our understanding of how climate change impacts the marine environment. Ocean temperatures, weather and climatic changes greatly influence the amount and location of nutrients in the water column. If temperatures and currents change, the plankton production cycle may not coincide with the reproduction cycle of fish. The above changes are closely related to the changes in radiative forcing, which initiate feedback mechanisms like changes in surface temperature, circulation, and atmospheric chemistry.
Download or read book Changing Sea Levels written by David Pugh and published by Cambridge University Press. This book was released on 2004-04 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flooding of coastal communities is one of the major causes of environmental disasters world-wide. This textbook explains at a basic level, how sea levels are affected by astronomical tides, by weather effects that generate extreme flooding events, and over the longer term by ocean circulation and climate trends. It also indicates how sea level changes are related to changing risks, coastal dynamics, geology and biology; and outlines some of the economic and legal implications. Based on courses taught by the author in the UK and the USA, this book is aimed at undergraduate students at all levels, with the text developed in such a way that non-basic mathematics is confined to Appendices and a web site (http://publishing.cambridge.org/resources/0521532183/). Changing Sea Levels will also interest and inform professionals in many fields including hydrography, coastal engineering, geology, biology and also coastal planning and economics.

Book excerpt: The World Wildlife Fund (WWF) and the Marine Conservation Biology Institute (MCBI) present the full text of the report entitled "Turning up the Heat: How Global Warming Threatens Life in the Sea," written by Amy Mathews-Amos and Ewann A. Berntson. Scientific evidence suggests that marine species and ecosystems are already affected by global climate change. The consequences of global warming on marine life include the fact that some organisms cannot survive in warmer waters, while others may shift their distribution poleward.

Available in PDF, EPUB and Kindle. Book excerpt: The Earth's climate is already warming due to increased concentrations of human-produced greenhouse gases in the atmosphere, and the specter of rising sea level is one of global warming's most far-reaching threats. Sea level will keep rising long after greenhouse gas emissions have ceased, because of the delay in penetration of surface warming to the ocean depths and because of the slow dissipation of excess atmospheric carbon dioxide. Adopting a long perspective that interprets sea level changes both underway and expected in the near future, Vivien Gornitz completes a highly relevant and necessary study of an unprecedented age in Earth's history. Gornitz consults past climate archives to help better anticipate future developments and prepare for them more effectively. She focuses on several understudied historical events, including the Paleocene-Eocene Thermal Anomaly, the Messinian salinity crisis, the rapid filling of the Black Sea (which may have inspired the story of Noah's flood), and the Storrega submarine slide, an incident possibly connected to a sea level occurrence roughly 8,000 years old. By examining dramatic variations in past sea level and climate, Gornitz concretizes the potential consequences of rapid, human-induced warming. She builds historical precedent for coastal hazards associated with a higher ocean level, such as increased damage from storm surge flooding, even if storm characteristics remain unchanged. Citing the examples of Rotterdam, London, New York City, and other forward-looking urban centers that are effectively preparing for higher sea level, Gornitz also delineates the difficult economic and political choices of curbing carbon emissions while underscoring, through past geological analysis, the urgent need to do so.
Download or read book Climate Change and Marine Geological Dynamics written by George Kontakiotis and published by Mdpi AG. This book was released on 2021-11-11 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tendency for climate to change has been one of the most surprising outcomes of the study of Earth's history. Marine geoscience can reveal valuable information about past environments, climates, and biota just before, during and after each climate perturbation. Particularly, certain intervals of geological records are windows to key episodes in the climate history of the Earth-life system. Ιn this regard, the detailed analyses of such time intervals are challenging and rewarding for environmental reconstruction and climate modelling, because they provide documentation and better understanding of a warmer-than-present world, and opportunities to test and refine the predictive ability of climate models. Marine geological dynamics such as sea-level changes, hydrographic parameters, water quality, sedimentary cyclicity, and (paleo)climate are strongly related through a direct exchange between the oceanographic and atmospheric systems. The increasing attention paid to this wide topic is also motivated by the interplay of these processes across a variety of settings (coastal to open marine) and timescales (early Cenozoic to modern). In order to realize the full predictive value of these warm (fresh)/cold (salty) intervals in Earth's history, it is important to have reliable tools (e.g., integrated geochemical, paleontological and/or paleoceanographic proxies) through the application of multiple, independent, and novel techniques (e.g., TEX86, UK'37, Mg/Ca, Na/Ca, Δ47, and μCT) for providing reliable hydroclimate reconstructions at both local and global scales.

Download or read book Correlation of High Order Cycles in the Marine paralic Transition of the Upper Middle Devonian Givetian Moscow Formation Eastern New York State written by Alexander J. Bartholomew and published by . This book was released on 2002 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The upper Middle Devonian (Givetian) Moscow Formation of the Hamilton Group was deposited in a subsiding foreland basin north of the advancing Acadian Highlands. The Moscow Formation overall represents a third-order cycle of relative sea-level variation that contains six and one-half subsequences of sea-level fluctuation, regarded as fourth-order cycles. Smaller-scale subsequences of the Moscow Formation have previously been correlated east to the Oneonta area in Otsego Co. Correlations were carried eastward to Schenevus and Summit and then the Schoharie Valley. Definite identification of these subsequences is possible to Summit. Eastward of Summit, the overall pattern of relative sea-level oscillation is still discernable, although the distinguishing characteristics of the subsequence have changed. Third-order cycle of sea-level oscillation represented by the Moscow Formation displays an overall shallowing-to-deepening-upward trend in the western portions of New York State. This pattern switched to a shallowing-upward pattern in the Schoharie Valley, with the upper portion of the Moscow Formation being represented by terrestrial floodplain sediments. This change in pattern is due to a switching from allocyclic (eustatic) control on deposition in the west to control by autocyclic (deltaic) processes in the east. Although the third-order pattern of deposition has changed in the Moscow Formation in the Schoharie Valley, the pattern of the fourth-order cycles can still be discerned, indicating that eustatic sea-level fluctuation still exerts control on deposition. Five levels of the Gilboa Forest are found to be contained within the Moscow Formation. The stumps of progymnosperm trees were found to be encased within the sandstones that correlate to the transgressive portions of the subsequences in the west. Correlation of subsequences of the Moscow Formation into this region allows for a more detailed analysis of the contact between the Moscow Formation and the Tully Formation. Above the uppermost subsequence of the Moscow Formation in this region is about 60 meters of redbeds that have previously been assigned to the Moscow Formation. These can now be shown to be equivalent to the deposits of the lower and middle Tully Formation in the west, with the overlying Gilboa Formation equivalent to the upper Tully and overlying Genesee formations.

Download or read book The Terrestrialization Process written by Marco Vecoli and published by Geological Society of London. This book was released on 2010 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invasion of the land by plants (terrestrialization) was one of the most significant evolutionary events in the history of life on Earth, and correlates in time with periods of major palaeoenvironmental perturbations. The development of a vegetation cover on the previously barren land surfaces impacted on the global biogeochemical cycles and the geological processes of erosion and sediment transport. The terrestrialization of plants preceded the rise of major new groups of animals, such as insects and tetrapods, the latter numbering some 24 000 living species, including ourselves. Early land-plant evolution also correlates with the most spectacular decline of atmospheric CO2 concentration of Phanerozoic times and with the onset of a protracted period of glacial conditions on Earth. This book includes a selection of papers covering different aspects of the terrestrialization, from palaeobotany to vertebrate palaeontology and geochemistry, promoting a multidisciplinary approach to the understanding of the co-evolution of life and its environments during Early to Mid-Palaeozoic times.
