Description:

Abstract:

This data layer is a point coverage of known sediment samplings, inspections and probings from the usSEABED data collection and integrated using the software system dbSEABED. This data layer represents the calculated (CLC) output of the dbSEABED mining software. It contains results from calculating variables using empirical functions working on the results of extraction or parsing. The CLC data is the most derivative and certainly the least accurate; however, many clients appreciate that it extends the coverage of map areas with attributes, especially physical properties attributes.

Purpose:

To build a digital mapping of the character of the seabed on regional, national and global scales. These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracy of each attribute is dependent on the accuracy of the lineage data.

Logical_Consistency_Report:

Data in usSEABED 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 absence) or information can be noted.

Completeness_Report:

Additional useable data may exist in this area; the authors appreciate any information and leads.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Locational accuracy is dependent on the accuracy of the navigational technique from the individual data sources and may vary widely (e.g., from 0.005km (differential GPS) in more recent surveys to greater than 2 km based on radar, Loran, or dead reckoning in older surveys.) Users of the data should use their own criteria for assessing the accuracy of the locations.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Locational accuracy is dependent on the accuracy of the navigational technique from the individual data sources. Users of the data should use their own criteria for assessing the accuracy of the locations.

Process_Step:

Process_Description:

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 01/05/2006) for correctness of formatting. Data are compiled into source data resource files (DRF) and processed through the dbSEABED data mining program (MNEt, version 04/07/2006) program, using the dbSEABED thesaurus (db9_dct.rtf, version 04/07/2006) and facies set up file for U.S. waters (db9_FAC.txt, version 04/07/2006). 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. Please review the Larger_Work_Citation for information about how the data are compiled, integrated, and processed in the usSEABED database.

Process_Step:

Process_Description:

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.). In attributes with range domains, a value of 9999 was entered in the minimum and maximum values to indicate the original metadata did not contain the required information. Minor fixes to the attribute format for some attributes were needed. 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.
