Manheim (editor) Laura Hayes (editor) 2002 tabular data U.S. Geological Survey Professional Paper PP-1634 Reston, VA U.S. Geological Survey https://doi.org/10.3133/pp1634 http://pubs.usgs.gov/pp/p1634/ 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 The data were obtained from a variety of sources: published reports, theses, unpublished data from agencies and organizations in Louisiana, and Federal agencies such as the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, NOAA,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). The data are preliminary results of a project to develop a comprehensive database of chemical and environmental information on sediments from Lake Pontchartrain, LA, and surrounding water bodies. The goal is to evaluate all data for reliability and comparability, make them widely accessible to all users, and interpret the data with respect to the environmental status of these important estuaries. It is part of a larger 5-year research program investigating the geological framework of Lake Pontchartrain, LA (FY 1994-FY 1999), begun by S.J. Williams and currently under overall leadership of J.L. Kindinger (USGS, St. Petersburg, FL). 1963 1998 sample collection period Complete As needed -90.75 -89.25 30.42 29.75 USGS Metadata Identifier USGS:67df2f31-8a5d-4c20-8274-f70268d6ea13 USGS Thesaurus geochemistry limnology unconsolidated deposits grain-size analysis datasets ISO 19115 Topic Category geoscientificInformation none Mississippi Sound - Lake Borgne Lake Pontchartrain Lake Maurepas Intracoastal Waterway Augmented FIPS 10-4 and FIPS 6-4 f22105 = Tangipahoa f22063 = Livingston f22095 = St. John the Baptist f22051 = Jefferson f22071 = Orleans f22103 = St. Tammany none none Frank T Manheim U.S. Geological Survey, ER mailing address

Williams (Chief Scientist of the USGS Coastal and Marine Geology Program, Reston, VA) who provided the initial opportunity for this database development and supplied extensive documents that permitted initiation of data entry. J.L. Kindinger (USGS Coastal and Marine Geology Program, St. Petersburg, FL) provided cooperation throughout the work. A.G. McIntire (now U.S. Bureau of Census, Geography - TIGER Mapping Branch, Upper Marlboro, MD) entered many of the early data sets, converted the database to an initial Microsoft® Access format, and created many of the illustrations in the preliminary publication (Manheim, Hayes, and McIntire, 1998). G.C. Flowers (Tulane University Department of Geology, New Orleans, LA) provided an important unpublished electronic data set. We are grateful for the cooperation of J. Macauley and L. Harwell (US EPA, EMAP Program, Gulf Breeze, FL) for providing unpublished data and clarifying many details about the EMAP data for southern Louisiana estuaries. Finally, we are indebted to the many organizations and participants listed in Participants and Cooperators for the data and cooperation. Microsoft Excel, Microsoft Access A variety of methods were used to analyze the accuracy and suitability of data for their intended purposes. These are described in detail in the report, but include knowledgeable assessment of expected relationships among geochemical measures, inspection of the range of values present, bivariate plots of related measures, and comparison of nearby samples for anomalies. Assessments of the quality of individual measurements are included in the data as ancillary attributes; the report refers to these as "quality-control fields". The designation "W" in quality-control fields placed adjacent to data fields in the full database warns that the data in question appear to show unresolvable anomalies. "0" in a concentration field means that the constituent was analyzed and found to have a concentration below the detection limit for the method utilized. (Zeros are different, therefore, from blank fields, which show that the constituent was not measured). Other remarks in the quality-control fields provide comments relating to the data that may be helpful in interpreting or further evaluating the data. See appendix B for further explanations on quality control and codes. The data in this study have been acquired from historical sources as well as from ongoing field programs. It is not feasible to apply the standard quality-control protocols that check on the details of sampling and analytical methodology (see Baker and Kravitz, 1992) to heterogeneous data. To rescue data while minimizing problems associated with data comparability, special batch screening techniques were used to identify and call attention to data that have unresolved problems. Although such tests do not necessarily prove that the data are in error, they alert users to data that should be reevaluated or confirmed before use in environmental characterization. The report includes sample location maps (as images) that indicate the general distribution of analytical data. Empty cell values in tables indicate analyses that were not obtained from the given location. Some latitudes and longitudes listed for stations near New Orleans were found to plot on land, rather than offshore. Fortunately, supplementary site descriptions available in the original reference made better site identification possible in this case. Byrne, C.J.

Environmental issues include linking the chemical data to bulk sediment toxicity criteria, searching for possible contaminant sources, and identifying transport and geochemical processes. The in-depth inventory and assessment was only possible with the help of many partners and cooperators. The processing of the information took place from 1996 to 2001. The process date reflects the most recent date.

Reston VA 20192 USA (703) 648-6533 (703) 648-6560 pschweitzer@usgs.gov Edits to the metadata were made to fix any errors that MP v 2.9.50 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. Minor edits to the structure of the metadata were performed such as removing extra carriage returns. Numerous edits were made in the entity and attribute section to add expected elements to eliminate parsing error messages. This often meant adding the text "Information unavailable from original metadata" for those required fields that were absent. The DOI link was added to the identification section as well as to some cross-references. Added access instructions for the online resources. The metadata date (but not the metadata creator - which Peter set to himself) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent. Additional edits were probably made to the original metadata by someone else who did not document what they changed.
