Title:
usSEABED component and features data for the entire U.S. Atlantic Coast (ATL_CMP)
Abstract:
This component data layer (_CMP.txt) file gives information about selected components (minerals, rock type, microfossils, benthic biota) and seafloor features (bioturbation, structure, ripples) at a given site. Values in the attribute fields represent the membership to that attribute's fuzzy set. For components such as minerals, rocks, micro-biota and plants, and/or epifauna and infauna, corals and other geologic and biologic information, the value depends on sentence structure and other components in description. For features (denoted by an asterisk) such as ripples, ophiuroids, sponges, shrimp, worm tubes, lamination, lumps, grading, and/or bioturbation, the value of the fuzzy set depends on the development of the attribute. Only the relative fuzzy presence of components and features can be determined; the absence of information does not indicate a lack of the attribute, only lack of information about that attribute.
Supplemental_Information:
This layer can be used in a relational data base, using the DataSetKey to link to the ATL_SRC.txt file for brief metadata information and to formal metadata written on each source, and to the other data files of usSEABED using the SiteKey or SampleKey as relational links.

Why was the data set created?

The component data file (_CMP.txt) can be used to investigate the relative presence of various constituents and the development and expression of selected seafloor characteristics.

How was the data set created?

  1. From what previous works were the data drawn?
    Varies with source (source 1 of 1)
    Various, unknown, See separate listing, ATL_SRC.txt, and links provided therein, within data publication (see Larger_Work_Citation) for the specific sources and associated metadata.: Various publishers/originators, Various publication places.

    Other_Citation_Details:
    X number of sources, both published and unpublished, are used as the sources of information for usSEABED. Metadata for each source is linked through the usSEABED source file (ATL_SRC.txt). Sources include the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), Minerals Management Service (MMS), National Oceanic and Atmospheric Administration (NOAA), Virginia Institute of Marine Science (VIMS), the Maryland and New Jersey State Geological Surveys (MGS, NJGS), NOAA's National Geophysical Data Center (NGDC), the Smithsonian Institution, and others.
    Type_of_Source_Media: Hard copy and digital
    Source_Contribution:
    Point locations, descriptions, and various analytical data (textural, granulometric, geochemical, geophysical, acoustic) on sediments, rock exposure, and benthos. Varies with source.
  2. How were the data generated, processed, and modified?
    Date: unknown (process 1 of 5)
    Source data may be digitized as necessary (typed or scanned in), with a visual inspection of digitized data to the source report and corrections as necessary, and are tested for completeness in Microsoft Excel as appropriate. Other digital data may be decoded using source-specific programs, downloaded via the web, or sent directly to the USGS or University of Colorado via email. Data are formatted into the dbSEABED Data Entry template (db9_DataEntry.xls, version 08/07/2004) by hand, and tested using the dbSEABED relational database program (RDBi, version 01/05/2005) for correctness of formatting. Data are compiled into source data resource files (DRF) and processed through the dbSEABED data mining program (MNEt, version 04/18/2005) program, using the dbSEABED thesaurus (db9_dct.rtf, version 04/07/2005) and component set up file for U.S. waters (db9_ABUN.txt, version 04/11/2005). Data are iteratively reprocessed and corrected until noted errors are fixed, as recorded by the _RBDS.2fx and _MNE.DGN files. Data are exercised in a GIS for location tests and useability.

    Data sources produced in this process:
    • ATL_CMP.txt
    Date: 23-Jan-2017 (process 2 of 5)
    Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Fixed a link in the distribution section. Minor fixes to the attribute format for some attributes were needed. The original metadata appeared to have 2 sets of attributes - one where the attributes were all upper-case. These upper-case attributes only had the attribute label. When an attribute of the same label (but difference case) existed, the all upper-case attribute was deleted. Attempted to modify http to https where appropriate. The metadata date (but not the metadata creator) 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. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Accuracy of each attribute is dependent on the accuracy of the original source description and the values calculated by the mining software, dbSEABED. Values are based on filters using fuzzy set theory and represent a measure of truth about the attribute.
  2. How accurate are the geographic locations?
    Locational accuracy is dependent on both the accuracy of the navigational technique and the level of detail about the location as recorded in the individual data sources, and may vary widely (e.g., from 0.005 km (differential GPS) in the more recent surveys to greater than 2 km based on radar, Loran, or dead reckoning in the older surveys. Users of the data should note the metadata written about the original sources and use their own criteria for assessing the accuracy of the locations.
  3. How accurate are the heights or depths?
    Depth determinations, both water depth and subsample depth, are dependent on the accuracy of the depth determination technique and the level of detail noted in the original source. Users of the data should note the metadata written about the original sources and use their own criteria for assessing the accuracy of the locations.
  4. Where are the gaps in the data? What is missing?
    Additional useable data may exist in this area; the authors appreciate any information and leads.
  5. How consistent are the relationships among the observations, including topology?
    Data in the usSEABED data collection are based on the observations and analyses of others, filtered through a unifying and mining software. Each source report varies in type of information/data recorded and format. Only those observations that are recorded can be filtered and mined; only presence (not absences) of information can be noted.

How can someone get a copy of the data set?
