Sediment Database and Geochemical Assessment of Lake Pontchartrain Basin

Detailed chemical, station (source and documentation, sample locations), and texture data are provided for bottom sediments of Lake Pontchartrain, Louisiana. The sediment data are provided as spreadsheet (Microsoft Excel), database (Microsoft Access), and tab-delimited files on CD-ROM and web site. The browser format is the same for both mediums. These data are in the form of appendixes at the end of the report, which provides extensive supporting data, interpretive diagrams, and discussion. The data were obtained from a variety of sources: published reports, theses, unpublished data from agencies and organizations in Louisiana, and Federal agencies such as the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, NOAA, National Status and Trends benthic surveillance program, and U.S. Geological Survey (publications and new field data).
