Louisiana
September 29, 2016

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

Freshwater withdrawals and population in Alabama, 1960-2005
September 28, 2016

Since 1950 when the U.S. Geological Survey (USGS) first conducted water-use compilations, important changes in water use have occurred in Alabama. The early part of the history (1950 to 1980) showed a steady increase in water use. During this time, the expectation was that, as the population increased, so would water use. Contrary to this expectation, reported water withdrawals declined...

Hurricane Potential in the United States and Puerto Rico
September 26, 2016

Hurricanes bring destructive winds, storm surge, torrential rain, flooding, and tornadoes. A single storm can wreak havoc on coastal and inland communities and on natural areas over thousands of square miles. In 2005, Hurricanes Katrina, Rita, and Wilma demonstrated the devastation that hurricanes can inflict and the importance of hurricane hazards research and preparedness.

Biomarkers reveal sea turtles remained in oiled areas following the Deepwater Horizon oil spill

Assessments of large-scale disasters, such as the Deepwater Horizon oil spill, are problematic because while measurements of post-disturbance conditions are common, measurements of pre-disturbance baselines are only rarely available. Without adequate observations of pre-disaster organismal and environmental conditions, it is impossible to assess...

Greenhouse gas emissions from a created brackish marsh in eastern North Carolina

Tidal marsh creation helps remediate global warming because tidal wetlands are especially proficient at sequestering carbon (C) in soils. However, greenhouse gas (GHG) losses can offset the climatic benefits gained from C storage depending on how these tidal marshes are constructed and managed. This study attempts to determine the GHG emissions...
