Why was the data set created?

The component data file (PAC_CMP.txt) can be used to investigate the relative presence of various constituents and the development and expression of selected sea floor 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 Data Sources page (<https://pubs.usgs.gov/ds/2006/182/pac_sources.html> and links therein), or the relationally linked file PAC_SRC.txt (<https://pubs.usgs.gov/ds/2006/182/data/data/pac_src.txt>), and links therein, within the data publication (<https://pubs.usgs.gov/ds/2006/182/>) for the specific sources and associated metadata.: Various publishers/originators, Various publication places.

   Other_Citation_Details:

   Over 300 sources, both published and unpublished, are used as the sources of information for usSEABED. Metadata for each source is given through the Data Sources page (<https://pubs.usgs.gov/ds/2006/182/pac_sources.html>) and relationally linked to the data through the file <https://pubs.usgs.gov/ds/2006/182/data/pac_src.txt> (PAC_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), the University of Washington, Seattle, Oregon State University, Corvallis, Universities of California, Berkeley, Los Angeles, and San Diego, University of Southern California, San Jose and Humboldt State Universities, Naval Postgraduate School, Virginia Institute of Marine Science (VIMS) and other educational institutions, the Maryland and New Jersey State Geological Surveys (MGS, NJGS), U.S. Navy, Southern California Coastal Water Research Project (SCCWRP), other local and regional consortia and authorities, 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. Contributions vary with source.

2. How were the data generated, processed, and modified?

   Date: 23-Dec-2006 (process 1 of 1)

   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 05/27/05) by hand, and tested using the dbSEABED relational database program (RDBi, version 01/05/2005) for correctness of formatting. For consistency, simple unit changes may be done. Data are compiled into source data resource files (DRF) and were processed on 12/22/05 through the dbSEABED data mining program (MNEv, version 12/18/2005) program, using the dbSEABED thesaurus (db9_dict.rtf, version 10/29/2005) and component set up file for U.S. waters (SET_ABUN.txt, version 07/20/2005). 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.

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?

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints:

Public domain data from the U.S. Government are freely redistributable with the proper metadata and source attribution. Please recognize the U.S. Geological Survey (USGS) as the source of this information.
