Available in PDF, EPUB and Kindle. Book excerpt: Coral-based proxy records are one of the most powerful tools for extending our understanding of interannual to centennial modes associated with El Niño-Southern Oscillation (ENSO) variability. Such records are also crucial for constraining forecasts under various greenhouse gas emission scenarios. In this dissertation I present an examination of records obtained from two study sites: The Republic of Palau (7.5°N 134.5°E) and Easter Island (27°S 109°W). This dissertation is organized into five chapters and an appendix. Chapter 1 is an introduction to paleoclimate, ENSO, and coral-based proxy records. In Chapter 2, I present the analysis of four records from Palau that were sampled from diverse localities within this study region. We take advantage of the multiple instrumental products and previously published results in our evaluation of the Palau coral [delta] 18O ([delta] 18OCRL) signal. Our primary conclusion in Chapter 2 is that Palau [delta] 18OCRL is well suited to capture ENSO, regardless of the coral environmental setting. We also show that Palau [delta] 18OCRL is primarily related to salinity, with temperature exerting a secondary influence. In Chapter 3 we apply our [delta] 18OCRL calibration results from Palau to the pre-instrumental period. Our records exhibit excellent reproducibility over the 20th century, and show strong coherence with other tropical Pacific [delta] 18OCRL records. We identify a 23/24 year cycle which is robust throughout the West Pacific Warm Pool (WPWP) following the end of the Little Ice Age (LIA). The Palau records show a long-term trend indicative of warming and/or freshening. Chapter 4 presents the results of three previously unpublished [delta] 18OCRL records from Easter Island, which resides in a region that is particularly devoid of high-resolution paleoclimate observations. All of the Easter Island corals display complex growth morphology. As a result, we deploy a range of techniques to develop age models. Our chief conclusion is that the Easter Island [delta] 18OCRL records closely follow hemispheric and global scale temperature trends over the 20th century. We also observe unique seasonal trends, which are likely attributable biases in seasonal carbonate precipitation and our age model schemes. Our analyses of the Easter Island [delta] 18OCRL records support the assertion that decadal variability across the Pacific basin originates in the tropics. All of the [delta] 18OCRL records presented in this dissertation represent significant contributions our understanding of Pan-Pacific climate variability over the past two centuries.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Book excerpt: Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Following this, a series of chapters written by scientific leaders worldwide synthesizes the problems and offers solutions for specific issues graded within the framework of the socio-economic-environmental mosaic. These include fisheries, climate change, coastal megacities, evolving human-nature interactions, remediation measures, and integrated coastal management. The problems faced by half of the world living near coasts are truly a worldwide challenge as well as an opportunity for scientists to study commonalities and differences and provide solutions. This book is centered around the proposed DAPSI(W)R(M) framework, where drivers of basic human needs requires activities that each produce pressures. The pressures are mechanisms of state change on the natural system and Impacts on societal welfare (including well-being). These problems then require responses, which are the solutions relating to governance, socio-economic and cultural measures (Scharin et al 2016). - Covers estuaries and coastal seas worldwide, integrating their commonality, differences and solutions for sustainability - Includes global case studies from leading worldwide contributors, with accompanying boxes highlighting a synopsis about a particular estuary and coastal sea, making all information easy to find - Presents full color images to aid the reader in a better understanding of details of each case study - Provides a multi-disciplinary approach, linking biology, physics, climate and social sciences
