Since the second half of the 20th century, there has been an increase in scientific interest, research effort, and information gathered on the geologic sedimentary character of the continental margins of the United States. Data and information from thousands of sources have increased our scientific understanding of the geologic origins of the margin surface but rarely have those data been combined into a unified database. Initially, usSEABED was created by the U.S. Geological Survey (USGS), in cooperation with the Institute of Arctic and Alpine Research at the University of Colorado Boulder, for assessments of marine-based aggregates and for studies of sea-floor habitats by the U.S. Geological Survey (USGS). Since then, the USGS has continued to build up the database as a nationwide resource for many uses and applications. Previously published data derived from the usSEABED database have been released as three USGS data series publications containing data covering the U.S. Atlantic margin, the Gulf of Mexico and Caribbean regions, and the Pacific coast (Reid and others, 2005; Buczkowski and others, 2006; and Reid and others, 2006). This expanded USGS data release unifies the data from these three publications and includes an additional 54 data sources added to usSEABED since the original data series, provides revised output files, and expands the data coverage to include usSEABED data from all areas within the U.S. Exclusive Economic Zone (EEZ) as of the time of publication (including Alaska, Hawaii, and U.S. overseas territories). The usSEABED database was created using the most recent stable version of the dbSEABED software available to the USGS at the time of release (specifically, dbSEABED software [NMEv, version date 4/23/2010] using the dbSEABED thesaurus [db9 dict.rtf, version date 8/21/2009], the component set up file for U.S. waters [SET ABUN 2016.txt, version date 5/29/2016], and the facies set up file for U.S. waters [SET FACI.txt, version date 3/16/2012]). The USGS Open-File Report "Sediments and the sea floor of the continental shelves and coastal waters of the United States: About the usSEABED integrated sea-floor-characterization database, built with the dbSEABED processing system" (Buczkowski and others, 2020) accompanies this data release and provides information on the usSEABED database as well as the dbSEABED data processing system. Users are encouraged to read this companion report to learn more about how usSEABED is built, how the data should be interpreted, and how they are best used.

bmi_dbseabed provides a set of functions that allow downloading of the dataset from dbSEABED (https://instaar.colorado.edu/~jenkinsc/dbseabed/), a system for marine substrates datasets across the globe. bmi_dbseabed also includes a Basic Model Interface (BMI https://bmi.readthedocs.io/en/latest/) that can be used for data/model coupling under the PyMT modeling framework.

pymt_dbseabed is a package that uses the bmi_dbseabed pacakge to convert dbSEABED datasets into a reusable, plug-and-play data component for PyMT modeling framework. This allows dbSEABED datasets to be easily coupled with other datasets or models that expose a Basic Model Interface.

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 parsed (PRS) output of the dbSEABED mining software. It contains the results of parsing descriptions in the data resources. The PRS data is less precise because it comes from word-based descriptions, but will include information on outsized elements, consolidation that are not usually in EXT data.

We are still in a development mode and working in particular and the namespace URI's and their hosting. So some elements here will change as we tweak responsibility for maintaining namespaces and curating them. You are welcome (encouraged) to explore our sparql endpoint (http://data.oceandrilling.org/sparql) and engage us, comment and criticize. (Doug)

This site is guided by the linked data pattern (http://linkeddata.org/). Information on this effort and the steps being taken to expose data in this approach are described here.

This data represents only a small percentage of the data available but is sufficient for testing at this time. Additional data related to log files from LDEO, timescales from CHRONOS and data from TAMU are yet to be loaded.

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 extracted (EXT) output of the dbSEABED mining software. It contains data items which were simply extracted from the data resources through data mining. The EXT data is usually based on instrumental analyses (probe or laboratory) but may apply to just a subsample of the sediment (eg. no large shells).

This data layer (PAC_EXT.txt) is one of five point coverages of known sediment samples, inspections, and probes from the usSEABED data collection for the U.S. Pacific continental margin integrated using the software system dbSEABED. This data layer represents the extracted (EXT) output of the dbSEABED mining software and contains data items which were extracted from the data resources files and generally represent lab-based analytical data. The EXT data are usually considered the most rigorous data available, although some data may represent a subsample of the sediment (that is, large shells or stones may have been excluded from the analysis). This file contains the same data fields as the parsed (PAC_PRS) and calculated (PAC_CLC) data files, and the three files may be combined.Please note that this data has been clipped and reprojected for purposes of the San Diego Ocean Planning Partnership, a collaborative pilot project between the California State Lands Commission and the Port of San Diego.

This data layer (PAC_CLC.txt) is one of five point coverages of known sediment samples, inspections, and probes from the usSEABED data collection for the U.S Pacific continental margin integrated using the software system dbSEABED. This data layer represents the calculated (CLC) output of the dbSEABED mining software. Data in this file extend variables determined through the data extraction (EXT) and data parsing (PRS) processes of dbSEABED, calculated using empirical relations or known functions. The CLC data is the most derivative and least accurate of the usSEABED data files and should be used with caution; however, many users may appreciate that it extends the coverage of map areas with attributes, especially physical properties attributes. Please refer to the dbSEABED page (https://pubs.usgs.gov/ds/2006/182/dbseabed.html), and the Frequently Asked Questions (https://pubs.usgs.gov/ds/2006/182/faq.html) pages for more information on the calculation process. This file contains the same data fields as the extracted (PAC_EXT) and parsed (PAC_PRS) data files, and the three files may be combined.

The facies data layer (_FAC.txt)represents concatenated information about components (minerals and rock type), genesis (igneous, metamorphic, carbonate, terrigenous), and other appropriate groupings of information about the seafloor. The facies data are parsed from written descriptions from cores, grabs, photographs, and videos, and may apply only to a subsample as denoted by the Top, Bottom, and SamplePhase fields. Lack of values in a defined facies field does not necessarily imply lack of the components defining that field, but may imply a lack of data for that field.; abstract: The facies data layer (_FAC.txt) is a point coverage of known sediment samplings, inspections, and probings from the usSEABED data collection and integrated using the software system dbSEABED.

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.
