A synthesis of aquatic science for management of Lakes Mead and Mohave: U.S. Geological Survey Circular 1381
No full textLake Mead provides many significant benefits that have made the modern development of the southwestern United States possible. The lake also provides important aquatic habitat for a wide variety of wildlife including endangered species, and a diversity of world-class water based recreational opportunities for more than 8 million visitors annually. It is one of the most extensively used and intensively monitored reservoirs in the United States. The largest reservoir by volume in the United States, it supplies critical storage of water supplies for more than 25 million people in three western states (California, Arizona, and Nevada). Storage within Lake Mead supplies drinking water and the hydropower to provide electricity for major cities including Las Vegas, Phoenix, Los Angeles, Tucson, and San Diego, and irrigation of greater than 2.5 million acres of croplands.
Due to the importance of Lake Mead, multiple agencies are actively involved in its monitoring and research. These agencies have a long history of collaboration in the assessment of water quality, water-dependent resources, and ecosystem health. In 2004, the National Park Service obtained funds from the Southern Nevada Public Lands Management Act to enhance this partnership and expand monitoring and research efforts to increase the overall understanding of Lake Mead and Lake Mohave. Participating agencies included the National Park Service, Southern Nevada Water Authority, U.S. Geological Survey, Nevada Department of Wildlife, Bureau of Reclamation, U.S. Fish and Wildlife Service, University of Nevada, Las Vegas, and University of Nevada, Reno.
Results of these important efforts have been presented in Lake Mead Science Symposia conducted in 2009 and 2012. The relationships forged by the collaboration led to the development in 2012 of the Lake Mead Ecosystem Monitoring (LaMEM) Work Group, which has formalized the partnership and documented an interagency purpose and mission statement with common objectives for protection of Lake Mead and Lake Mohave water quality and water-dependent resources. This Circular has been developed to summarize the state of the knowledge related to the interests and objectives of the LaMEM Work Group, to inform management and the public of current lake conditions, and identify future needs for monitoring and research. It is hoped that this report will provide a framework for continued long-term investigations and analysis of the environmental health of Lakes Mead and Mohave

Stratigraphic evolution of the Ganges-Brahmaputra lower delta plain and its relation to groundwater arsenic distributions
No full textThroughout the Holocene, a large sediment load coupled with river avulsions, tectonic activity and eustasy developed the complex stratigraphy of the Ganges-Brahmaputra-Meghna delta. Understanding this development is useful in predicting how the delta will respond to changes in the environmental setting such as climatic shifts and sea-level rise. The complex stratigraphy is also linked to high concentrations of naturally occurring arsenic in the shallow groundwater aquifers of Bangladesh through its controls on hydrogeology and aquifer biogeochemistry. This research investigates differences in the fluvio-deltaic deposits of the Ganges and Brahmaputra rivers, as well as differences in the tectonic setting across the lower delta plain. We investigate how these overarching controls influence stratigraphic architecture, the resulting aquifer systems, and ultimately arsenic distribution within the lower delta plain. A transect of 48 sediment cores spanning the lower delta plain of Bangladesh was drilled to a depth of 90m. Individual samples were analyzed for lithology, provenance and age to determine the stratigraphic architecture, the source of the sediments and the depositional history of the rivers. Delta stratigraphy was related to arsenic distribution by measuring groundwater arsenic near each borehole and combining this data with previously collected groundwater data. This study provides a better understanding of Holocene delta evolution and river behavior, as well as a more complete understanding of the geologic controls on arsenic and the characteristics of contaminant distribution in fluvial settings as they relate to stratigraphic features

No full textWhat does it mean to be an academic? A public intellectual? What is the role of the universities today? Who better to ask than the people who for decades have worked, taught, struggled and lived in these places. Steven Shapin is the Franklin L. Ford Research Professor of the History of Science at Harvard University. He was part of the Science Studies Unit at Edinburgh University in the 1970s and went on to co-author the influential Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life. In this book you can read about his journey through the heydays of Science Studies and his thoughts on the future of universities. In the Questions & Afthoughts series you will meet some of the finest and most distinguished senior professors—you will meet living history. They are interviewed by young graduate students, who are eager to learn from past experiences of trial and error in academia, both professionally and personally.What does it mean to be an academic?
