Description: This dataset is intended to be a companion layer to the U.S. Geological Survey (USGS) Data Series usSEABED Atlantic Coast Offshore Surficial Sediment extracted data for the entire U.S. Atlantic Coast. The usSEABED Extracted Data for the Entire U.S. Atlantic Coast depicts the point locations of known sediment samplings, inspections and probings from the usSEABED data collection which were integrated using the software system dbSEABED. These point locations were extracted from the database through data mining. The resulting dataset contains information on samples from 58 individual datasets collected by the USGS and other research projects, and includes data processed by the USGS sediment laboratory, in addition to datasets compiled from gray literature or unpublished sources. More information on this dataset can be found in the </SPAN></SPAN><A href="http://pubs.usgs.gov/ds/2005/118/htmldocs/data_cata.htm"><SPAN><SPAN>metadata document</SPAN></SPAN></A><SPAN><SPAN>. </SPAN></SPAN<SPAN><SPAN> <P>The data quality index is informed by a methodology developed and employed by the Massachusetts Division of Marine Fisheries (Ford &amp; Voss 2010) and the Massachusetts Office of Coastal Zone Management (Sampson &amp; Huntley 2015) and which assigns data quality values to variables including the age of the sample, the sampling device, and the analytical technique used.
