Results 111 - 120 of 617 listed alphabetically [list by similarity]

Enhancement of USGS scientific investigations in Texas by using geophysical techniques, 2005-10 [More info]: Annotated bibliography describing the use of electromagnetic surveying to understand the characteristics of aquifers and how they work.
Environmental Monitoring and Assessment Program Western Pilot Project - Conditions of North Dakota Perennial Streams for Water Chemistry and Mercury in Fish Tissue, 2000-2003 [More info]: Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.
Environmental Monitoring and Assessment Program Western Pilot Project - Information about selected fish and macroinvertebrates sampled from North Dakota perennial streams, 2000-2003 [More info]: Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for fish and aquatic insects (macroinvertebrates) to establish unbiased baseline data.
Environmental studies of the World Trade Center area after the September 11, 2001 attack [More info]: Report describing the results of an interdisciplinary environmental study of the World Trade Center (WTC) area after the attack on September 11, 2001. The investigations included imaging spectroscopy mapping and laboratory analysis.
Epic Flooding in Georgia, 2009 [More info]: In September of 2009, flooding in parts of Georgia reached levels expected every 500 years. Specific measurements we made and other facts about these disasters described here should help people prepare for floods here and elsewhere.
Eruptions of Hawaiian volcanoes - past, present, and future [More info]: Originally published in 1987, this general-interest booklet has been revised in anticipation of the Centennial of the Hawaiian Volcano Observatory (HVO) in January 2012.
Estimated freshwater withdrawals in Oklahoma [More info]: Freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal data from ground water and surface water for domestic, commercial and agricultural use.
Estuaries of the Greater Everglades Ecosystem: Laboratories of Long-term Change [More info]: Explains how we reconstruct past environmental conditions, especially salinity, to help guide ecosystem restoration efforts in this area.
Everglades Depth Estimation Network (EDEN) for support of biological and ecological assessments [More info]: Integrated network of real-time water-level monitoring, ground-elevation modeling, and water-surface modeling that provides scientists and managers with current on-line water-depth information for the entire freshwater portion of the Greater Everglades.
Extreme drought to extreme floods: summary of hydrologic conditions in Georgia, 2009 [More info]: Discusses the nature and extent of extreme hydrologic events, with supporting observations of the water conditions and their effects on human activities.
