Download or read book Easter Island written by John Loret and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Easter Island, a World Heritage Site is still, after over 50 years since Thor Heyerdahl's work on the island, a fascinating area to explore and learn about a culture that has only remnants remaining, while documenting a marine ecology still mostly unknown. Easter Island: Scientific Exploration into the World's Environmental Problems in Microcosm presents the research results from three years of interdisciplinary expeditions to Easter Island. The primary objectives were to investigate the effects of human population growth on the ecology of the island and to discover whether any dramatic climatic changes such as a prolonged El Niño could have disrupted the island's fragile ecosystem. The interdisciplinary scientific team were mainly researching the paleontology, archaeology, climatology, and geophysics of the island. This book now brings together the results of the three expeditions, identifies new areas of research, and hopefully will continue to inspire aspiring scientists to revisit this amazing island to explore and demystify this timeless enigma of human history.
Book Synopsis Global Ecological Consequences of the 1982-83 El Niño-Southern Oscillation by : P.W. Glynn
Download or read book Global Ecological Consequences of the 1982-83 El Niño-Southern Oscillation written by P.W. Glynn and published by Elsevier. This book was released on 1990-09-06 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: El Niño is a meteorologic/oceanographic phenomenon that occurs sporadically (every few years) at low latitudes. It is felt particularly strongly in the eastern Pacific region, notably from the equator southwards along the coasts of Ecuador and Peru. The El Niño is a component of the ENSO (El Niño Southern Oscillation) which accentuates the intimate and causal connection between atmospheric and marine processes. Obvious manifestations of El Niño in the eastern Pacific are anomalous warming of the sea; reduced upwelling; a marked decline in fisheries, and high rainfall with frequent flooding. The 1982/83 El Niño was exceptionally severe, and was probably the strongest warming of the equatorial Pacific Ocean to occur during this century. The warming was intense and spread over large parts of the Pacific Ocean and penetrated to greater depths than usual. Many eastern Pacific coral reefs that had exhibited uninterrupted growth for several hundred years until 1983 were devasted by the disturbance and are now in an erosional mode. Marine species were adversely affected. The consequent depletion of the plant food base resulted in significant reductions in stocks of fish, squid etc. This led to a mass migration and near-total reproductive failure of marine birds at Christmas Island. Emphasis in this volume is placed on disturbances to benthic communities; littoral populations; terrestrial communities and extratropical regions.
Book Synopsis El Niño-Southern Oscillation (ENSO) and Tropical Pacific Climate Across the 4.2 Ka BP Climate Excursion by : Karen V. Gutierrez
Download or read book El Niño-Southern Oscillation (ENSO) and Tropical Pacific Climate Across the 4.2 Ka BP Climate Excursion written by Karen V. Gutierrez and published by . This book was released on 2021 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin and influence of the "4.2 kyr event"--a climate excursion characterized by century-long drought hypothesized to have affected civilizations throughout the northern subtropics--is uncertain, despite its registration in multiple paleoclimatic archives. As the dominant source of global interannual climate variability, the El Niño-Southern Oscillation (ENSO) might be expected to have shaped the expression of global precipitation and temperature across the 4.2 kyr event. However, the role of ENSO has not been explored, owing to a general lack of temporally extended observations in the tropical Pacific. Here I analyze a number of tropical Pacific Porites coral fossils spanning this interval, between ~4600 and 4100 years B.P., building on the previously published record of ENSO activity as well as the prevailing mean state of the tropical Pacific climate. Monthly resolved oxygen isotopic records of three corals from Fanning Island and one from Christmas Island overlap with and extend existing records to produce a nearly-continuous sequence that spans several hundred years. Oxygen isotopic values of the overlapping segments of the fossil corals strengthen the reliability of the paleoclimate record and the radiometric dating. The new coral data generated in this study confirm the previous inference of low ENSO activity over an extended time interval encompassing the 4.2 kyr event. Additionally, the new coral data show that the interannual variability, though reduced in amplitude relative to the modern climate, was expressed as repeated episodes of prolonged and intense La Niña conditions. This characterization stands in contrast with a single multi-decadal excursion, as initially hypothesized for the 4.2 kyr event. Finally, the mean values of overlapping coral segments from Fanning and Christmas Islands are similar, suggesting that the modern temperature and salinity gradient was not present during the interval of the 4.2 kyr event. The simplest explanation for this lack of temperature/salinity gradient is that the southern boundary of the North Equatorial Counter Current was shifted north of Fanning Island.

Book Synopsis Principles of Paleoclimatology by : Thomas M. Cronin
Download or read book Principles of Paleoclimatology written by Thomas M. Cronin and published by Columbia University Press. This book was released on 1999-07-27 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse gases, global warming, thinning ozone layers—understanding the Earth's climatic changes is one of today's most pressing international concerns. How fast has the climate changed? Where and why is it changing? What is the impact of climate change on our ecosystems, coastal regions, glaciers, forests, and lakes, and even on the evolution of our own species? This introduction to the rapidly emerging field of paleoclimatology explains the patterns and processes in the history of the Earth's climate to answer such essential questions. Using the geologic records of ocean and lake sediment, ice cores, corals, and other natural archives, Principles of Paleoclimatology describes the history of the Earth's climate—the ice age cycles, sea level changes, volcanic activity, changes in atmosphere and solar radiation—and the resulting, sometimes catastrophic, biotic responses. These paleoclimate records provide a baseline against which we can compare modern climate trends. Designed to give a fundamental background—including both history and methodology—to the discipline of paleoclimatology, this book is the first to advance our understanding of how climate change develops, how those changes are detected, and how the climate of the past can shape the climate of the future.

This volume compares ENSO's modern morphology and variability with its recent historic and prehistoric behaviour. It expands and updates Diaz and Markgraf's earlier volume El Niño: Historical and Paleoclimatic Aspects of the Southern Oscillation (1992, Cambridge University Press). The volume will be of importance to a broad range of scientists in meteorology, oceanography, hydrology, geosciences, ecology, public health, emergency management response and mitigation, and decision-making. It will also be used as a supplementary textbook and reference source in graduate courses in environmental studies.
Book Synopsis Global Climate Change and Response of Carbon Cycle in the Equatorial Pacific and Indian Oceans and Adjacent Landmasses by : Hodaka Kawahata
Download or read book Global Climate Change and Response of Carbon Cycle in the Equatorial Pacific and Indian Oceans and Adjacent Landmasses written by Hodaka Kawahata and published by Elsevier. This book was released on 2006-12-08 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand the global warming mechanism, global mapping of primary production was carried out under the GCMAPS program. The program was concerned with marine and terrestrial environmental changes, which affect carbon cycle on the regional and global scales. On the regional scale, warm phase of ENSO (El Niño / Southern Oscillation) has been shown to affect economic activities in many countries. The keyword for understanding mechanism of global warming is ‘primary productivity’. The earth observation satellites (EOS) like the ADEOS of Japan, and the SeaWiFS, Sea Star and Terra of the U.S.A. provided much required data for modeling and verification of primary production estimates on both land and ocean. The knowledge gained during the GCMAPS program has been documented in this book. Interpretation of the data suggests that global warming, which causes temperature and sea level rise, and changes in climate and ecosystems, is likely to have the largest influence on mankind. The first half of this book discuss changes in marine environments. Physical and chemical oceanographic properties of the equatorial Pacific and Indian Oceans are presented. Changes in partial pressure of carbon dioxide, flux and composition of settling particles and biological communities in the surface ocean have also been discussed. In addition to this, over hundred years of environmental records based upon coral skeletons are presented. Estimations of primary production and its utilization in validating satellite imagery data were conducted in the western North Pacific. Primary productivity estimates based upon the validated satellite imagery are presented on the global scale. Climate change modeling of primary production in global oceans is also presented. The latter half of this book deals with changes in terrestrial environments. Primary productivity estimates for different types of ecosystems (e.g., forest, grassland) are presented together with soil carbon dynamics. Also, biomass and productivity estimation and environmental monitoring based upon remote sensing techniques are presented with a model analysis of the relationship between climate perturbations and carbon budget anomalies in global terrestrial ecosystems. This book elucidates integrated aspects of the global carbon cycle involving marine and terrestrial environments. Discusses a current understanding of the biogeochemical processes on land and ocean Provides global mapping of primary production based on satellite imagery data and modelling Presents the latest interpretations of relationships between carbon cycle and climatic change
Book Synopsis The Quaternary Period in the United States by : A.R. Gillespie
Download or read book The Quaternary Period in the United States written by A.R. Gillespie and published by Elsevier. This book was released on 2003-12-17 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.
