Description:

Abstract:: Detailed chemical, station (source and documentation, sample locations), and texture data are provided for sediments in the Gulf of Maine. The sediment data are provided as spreadsheet (Microsoft Excel) and tab-delimited files on the web site. These data are in the form of sections within the web site, 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 The data were obtained from a variety of sources: published reports, theses, unpublished data from agencies and organizations in the Gulf of Maine area and Federal agencies such as the U.S. Army Corps of Engineers, U.S. Environmental Protection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).
Purpose:: The data are the results of a project to develop a comprehensive database of chemical and environmental information on sediments from the Gulf of Maine. 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 this important area.

Data_Set_Credit:

This publication is a product of many years of work by numerous organizations and individuals. Those persons listed as contacts in the Table of Collaborating, Participating, and Supporting Agencies (on the web site) were particularly crucial in providing contaminant data and context information to the authors. The search for references was greatly aided by the efforts of K. O'Connell, C. Hurter, M. Lydon, and P. Nelson. Data entry was expedited through efforts of K. O'Connell, J. Reid-Currence, E. Margolis, J. Wolfe and O. McCall. We thank L. Poppe and J. Hathaway for their extensive contributions of sediment texture data and information. Funding for this project was provided by the U.S. Geological Survey, Coastal Marine and Geology Program and by the Gulf of Maine Regional Marine Research Program grant NOAA# GMR-06.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

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 "qualifier fields."

"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.

Logical_Consistency_Report:

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.

Completeness_Report:

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.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Latitude and longitude coordinates are necessary for mapping data; however, their absence does not negate the value of other data reported for a sample. When numerical location data were not available, decimal latitudes and longitudes were estimated from maps or other information. Latitude and longitude values are specified in decimal degrees and were often calculated from individual degree, minute and second values. Any interpretation of mapped data should consequently utilize the location qualifier fields to understand the limitations of the spatial information.

Process_Step:

Process_Description:

The development of the current database involved four phases: 1) Discussions and interactions with knowledgeable individuals and agencies to identify and retrieve pertinent data from many sources, including unpublished data, 2) Selection and augmentation of a data dictionary to provide consistent field/ parameter definitions and background documentation, 3) Encoding and integration of the data tables in a master flat-file database system involving six basic tables linked by unique sample identification codes, 4) Selective querying, mapping, and interpretation of the data to identify potential outliers and quality problems and to identify key geochemical and environmental relationships and processes.

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.
