This book was released on 2015 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Laurentian Great Lakes contain approximately 2% of the world's freshwater and provide drinking water for more than 30 million people. Lake Erie is the shallowest and smallest of the Great Lakes. The western basin is the shallowest portion of Lake Erie and receives a majority of its water from the Maumee River and Detroit River. The Maumee River Watershed is the largest watershed in the Great Lakes and land use in the watershed dominated by urban and agricultural areas. Farm field run-off and combined sewer overflows from urban and agricultural areas contribute high concentrations of nutrients to the Maumee River. The high nutrient water flowing out of the Maumee River into the Western Basin of Lake Erie creates a good environment for Harmful Algal Blooms (HABs), which are primarily composed of Microcystis, to rapidly grow. HABs are a serious issue for Lake Erie because Microcystis produces a toxin that is harmful to humans. Research focused on decreasing HABs has identified phosphorus as the limiting nutrient. Phosphorus enters the lake through either external (phosphorus entering from outside the lake i.e. farm field run-off or inputs from tributaries) or internal loading (release of phosphorus from lake sediments). For Western Lake Erie, there are numerous studies on external loading of phosphorus, however there is considerably less research on internal phosphorus loading. Estimating internal loading of phosphorus is important because phosphorus concentrations in lake sediments can be orders of magnitude higher than phosphorus concentrations in lake water and can be a significant source of phosphorus. Phosphorus release rates from lake sediments can be affected by a variety of environmental factors such as pH, temperature, and dissolved oxygen concentration. If lake sediments become warmer and more hypoxic in response to climate change, the contribution of phosphorus from lake sediments may increase. The research conducted in this thesis investigates the effect of temperature on the release of phosphorus from anoxic lake sediments. This study aims to estimate phosphorus release rates for a range of temperatures under anoxic conditions for Western Lake Erie and to improve estimates of internal phosphorus loading. Sediment cores collected during the summer of 2014 and 2015 were incubated at 10°C, 20°C, 22°C, 27°C, and 30°C under anoxic conditions. Results from the sediment core incubations indicate that temperature, location, and duration of anoxia are significant influences on phosphorus release. Extrapolating the phosphorus release rates for the entire western basin, four days of anoxia at 30°C for the entire basin could result in the release of ~240 metric tons of phosphorus.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the proceedings of the 5th International Symposium on Shallow Lakes, held at Dalfsen, The Netherlands, in June 2005. The theme of the symposium was Shallow Lakes in a Changing World, and it dealt with water-quality issues, such as changes in lake limnology, especially those driven by eutrophication and pollution, increased nutrient loading and productivity, perennial blooms of cyanobacteria and loss of biodiversity.

Book excerpt: Nutrient enrichment of lakes is a ubiquitous problem, impacting ecological and human health on a global scale by accelerating the pace of eutrophication, often resulting in algal blooms, depleted dissolved oxygen concentrations, and economic harm to surrounding communities. In many lakes, bed sediments are a major but unrecognized source of phosphorus to the water, a process known as internal phosphorus loading. Internal loading is notoriously difficult to measure and manage given the need to access processes operating on and within the lakebed. In addition, climate change threatens to promote internal loading. For example, warming of lakes can increase the release of phosphorus from sediments due to 1) longer and stronger periods of lake stratification resulting in sediment anoxia and 2) enhanced microbial decomposition of organic matter. Degraded water quality not only impairs ecological health but also can influence social pride and community morale. This is the first book dedicated to the understanding of internal phosphorus loading in lakes and examines the causes, the ecological and societal impacts, and options for managing this complex phenomenon. With contributions from leading experts, this edited volume provides a broad view of internal phosphorus loading, methods for measurement, management practices for water quality improvement, case studies from around the world, and recommendations for addressing this growing concern. It is essential reading for environmental and engineering professionals involved in lake and reservoir management, students and faculty in limnology, state and federal authorities involved in water quality regulation, and lakefront homeowners and management boards interested in maintaining lake water quality and managing algal blooms.
