A Geographic Information System Database for Environmental Contaminants in the Rio Grande/Rio Bravo Basin
The assessment of contaminant stressors on biota of the Rio Grande/Rio Bravo resulted from an effort of the Biomonitoring for Environmental Status and Trends (BEST) program, to implement pilot projects to evaluate environmental contaminants and their effects on ecosystems. This study resulted in a database of approximately 2,600 concentration values that were georeferenced for use with Geographic Information Systems such as ArcView. The data and common domain software as well as other layers of information were incorporated into a CD-ROM that wildlife managers and biologists could use to query and obtain information on contaminants in biota of the Rio Grande/Rio Bravo. The database contains information on contaminants...
Total DDT Derivatives in Fish from the Davis Pond Freshwater Postdiversion Sampling (2007-2009) with a Comparison to Prediversion Levels (2001)
The diversion of freshwater from the Mississippi River is intended to mitigate saltwater intrusion from the Gulf of Mexico and to lessen the concomitant loss of wetland areas. Though effective, freshwater diversion can affect wildlife and habitat; therefore, prediversion and postdiversion data collections are necessary to identify effects. The Davis Pond freshwater diversion area is located between the Mississippi River and Bayou Lafourche and extends to Barataria Bay Basin, Louisiana. Results and interpretations from the prediversion biomonitoring done in 2001- which included data on fish, eagles, and bivalves - are presented in the U.S. Geological Survey (USGS) Scientific Investigations Report 2008-5067, "Davis...
