Hydrology and Water Chemistry in Weeks Bay, Alabama: Implications for Mercury Bioaccumulation

Monrreal, Robert (2007-08-15)

Recent studies within Weeks Bay, an estuary of Mobile Bay, have revealed that both water and fish are contaminated by mercury (Hg), an element known to be extremely toxic to wildlife and humans. Seasonal variations of ...

Interaction of Groundwater, Surface Water, and Seawater in Wolf Bay, Weeks Bay, and Dauphin Island Coastal Watersheds, Alabama

Beasley, Lee R. (2010-05-19)

Freshwater residing in coastal plain aquifers and watersheds represents one of our nation’s most important natural resources. Globally, the distribution and fluxes of freshwater in many coastal settings remains poorly ...

Limitations of the Microtremor Method: A Case Study in the Los Angeles Basin, California

Bose, Deblina (2010-08-02)

Microtremor data from 16 broadband seismic stations across the Los Angeles basin are used to explore limitations of Nakamura's (1989) method for estimating resonant frequencies, amplification, and ground vulnerability to ...

Linking Observed Seismicity to Crustal Structure in the New Madrid Seismic Zone Using Gravity and Magnetic Modeling

Eldridge, Caleb (2019-07-23)

The New Madrid Seismic Zone in the Central United States is a highly active seismic zone. Research has focused on the subsurface structure and history of development in order to gain better insight into the cause of these ...

Mineralogical and geochemical profiling of arsenic-contaminated alluvial aquifers in the Ganges-Brahmaputra floodplain Manikganj, Bangladesh

Shamsudduha, Mohammad (2007-08-15)

The present study investigated three major components – groundwater, sediment and minerals of arsenic-affected Quaternary alluvial aquifers in Manikganj town, which is located in one of the As-hotspots in central Bangladesh. ...

Modeling the Effects of Projected Sea Level Rise on Water Quality in Coastal Bangladesh

Shuman, Morgan (2015-05-04)

Climate models show that Bangladesh will experience high rates of change in temperature, precipitation, runoff, and local sea level rise rates by 2100. Sea level rise will result in the degradation of groundwater quality ...

Natural and Anthropogenic Contaminants in Groundwater and Cancer Cases in Fruithurst, Alabama
