This book was released on 2014 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication, a state in which a body of water becomes over-enriched with nutrients, remains one of the biggest water quality problems both in the United States and globally. Although nutrient pollution that causes eutrophication is regulated in the United States under the Clean Water Act (CWA), eutrophication remains a significant threat. Continued land-use change, internal regeneration of nutrients, and climate change all continue to contribute to nutrient loads that lead to eutrophication. This thesis is comprised of two chapters that aim to address the interplay between external and internal nutrient sources in lakes in the face of climate change. In the first chapter I examine how climate change impacts the internal nutrient cycling in two neighboring lakes in western Washington (USA). I found that climate variability can drive the internal regeneration of phosphorus in lakes that exhibit summer anoxia. This implies that climate change has the potential to increase nutrient loads in highly productive lakes, thereby increasing the risk of eutrophication in these systems in spite of control on external nutrient inputs. In the second chapter, I review the Clean Water Act and the policy tools implemented under it by which we manage external nutrient inputs. I found that the Clean Water Act is very good at addressing easy-to-identify point sources of nutrient pollution, but is much less effective at addressing diffuse, nonpoint sources. These results suggest that in order to maintain acceptable water quality in the future, we may need to be more aggressive with nonpoint source pollution that we currently are, particularly for productive lakes that exhibit summer anoxia. This information may also help managers allocate resources for nutrient control and identify lakes that are particularly at risk of eutrophication into the future.

It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." (The Holocene, November 2008) "If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." ( Journal of Phycology, 2008) “This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records.” Taken from the British Ecological Society’s Teaching Ecology website "John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." (Quaternary Science Reviews, 2009) “The breadth of coverage in this text is impressive.” (Lake and Reservoir Management, 2009) “If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful.” (Journal of Paleolimnology, 2009)
Download or read book Contaminants of the Great Lakes written by Jill Crossman and published by Springer Nature. This book was released on 2020-09-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the globally important freshwater resource of the Great Lakes, which is currently threatened by contaminants that compromise water quality and impact its ecological and economic health. Divided into four parts, this volume covers historic, current and emerging sources of contamination from heavy metals and persistent organic pollutants to microplastics; and identifies their ecological impacts. Due to factors ranging from rapidly changing land use practices, climate change and our emerging understanding of their impact on biological, chemical and physical interactions, the effectiveness of management strategies has proven highly variable. Continued enhancements in the rate of lake recovery are required to sustain the health of the Great Lakes. Accordingly, the book also explores recent advances in contaminant detection, along with future steps forward in lake management approaches. Revealing our current knowledge gaps and providing a roadmap towards sustainable solutions, the book offers a valuable asset for scientists, managers and the public alike.

Download or read book Management of Lakes and Reservoirs during Global Climate Change written by D. Glen George and published by Springer. This book was released on 2012-10-23 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: If present trends continue, most climatologists agree that the concentration of carbon dioxide in the atmosphere will have doubled by the year 2050. This increase in CO 2 will have a major effect on the global climate and substantially alter the physical, chemical and biological characteristics of lakes throughout the world. In recent years, it has become clear that year-to-year changes in the weather have a major effect on the seasonal dynamics of lakes. Many water quality problems that were once regarded as "local" phenomena are now known to be influenced by changes in the weather that operate on a regional or even global scale. For example, blooms of toxic blue-green algae can be induced by prolonged reductions in the intensity of wind-mixing as well as increased supplies of nutrients. Long-term studies in the English Lake District have shown that many of these variations are quasi-cyclical in nature and can be related to long-term changes in the distribution of atmospheric pressure over the Atlantic Ocean. It is not yet clear what effect these changes have on the dynamics of European lakes but much of the historical data required to extend these analyses to continental Europe is already available. In the early 1970s the International Biological Programme served as a particularly effective focus for comparative limnological research in eastern as well as western Europe.

This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.

Download or read book Global Issues in Water Sanitation and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2009-10-25 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.

Download or read book Lake Morphology and Nutrient Dynamics at Macroscales written by Samantha Kay Oliver and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have accelerated global nitrogen (N) and phosphorus (P) cycles, and excess nutrients have been the primary cause of water quality degradation. The transport of nutrients to lakes is dictated by processes operating at multiple spatial scales, from large-scale climate patterns to watershed-scale hydrology. In contrast, nutrient cycling within lakes is often constrained by lake-specific hydrology and morphology. Interactions between lake context, lake features, and biogeochemical cycles can create a patchwork of threats and responses across the landscape, making it difficult to generalize whether water quality will degrade or improve with ongoing environmental change. In this dissertation, I have advanced our knowledge of how local lake features, broad-scale environmental change, and distinct N and P cycles may interact to create patterns in water quality across the landscape. Local lake features such as depth and water residence time are important characteristics related to internal nutrient processing, but are unknown for most lakes. I found the relationship between lake surface area and depth varied by region and was a function of regional topography (Chapter 2). However, even when hundreds of lake depths are known in a region, prediction error remains high, stressing the importance of observed depth values. Though lake residence time is related to the absolute retention of N and P (Chapter 4), morphology and hydrology could not predict whether lakes more efficiently retain N or P. On average, lakes retain twice as much P relative to N and generally increase N:P for downstream systems. Differences in N and P biogeochemical cycles in lakes were also apparent in an assessment of nutrient and chlorophyll trends for nearly 3,000 lakes in the United States (Chapter 3). On average N, but not P or chlorophyll, has been declining since 1990. P trends were highly variable within regions, likely due to the watershed-scale transport and management of P, whereas N trends were more consistent within regions, reflecting the mobile nature and large-scale policy implementation to mitigate N deposition. These studies demonstrate that local lake features, distinct biogeochemical cycles, and management of N and P create variability in lake water quality across the landscape.
