The samples in this dataset were collected and analyzed under the direction of the Massachusetts Water Resources Administration. The data were generated to study the effects of the Boston sewage outflow. Data were previously incorporated into the USGS's Gulf of Maine Contaminated Sediments Database.
The purpose of this data layer is to release a digital version of the data published in Blake et al. (1993), Coats et al. (1994), Coats (1995), and Kropp and Diaz (1995) for interpretation of textural distributions.

Edits to the metadata were made to fix any errors that MP v 2.9.32 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.). The source information was incomplete and had to be modified to meet the standard. 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.
