Description:

Abstract:

This data set includes the locations, identifiers, grain-size data and(or) textural descriptions of surficial sediments collected at stations based on topographic and backscatter data of the seafloor in Boston Harbor and the harbor appraoches, Massachusetts. The sediments were collected with a modified Van Veen grab (mini-SEABOSS) during USGS survey 04019, conducted September 14-17, 2004.

Purpose:

This data set was produced to ground-truth (verify) topography and backscatter intensity of the seafloor in Boston Harbor and the harbor appraoches, Massachusetts. The acoustic data associated with this project were collected with multibeam, vertical-beam and sidescan sonar systems in 2000 and 2001, by NOAA NOS for hydrographic mapping purposes.

Process_Description:

Samples were collected by grab sampler and analyzed in the laboratory. Coarse fraction determined by sieve; fine fraction determined by Coulter Counter. Visual descriptions were used for rocky/bouldery stations where samples could not be collected. See Poppe, Williams, Paskevich (2005, http://woodshole.er.usgs.gov/openfile/of2005-1001/) for analytical specifics.

Process_Step:

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.30 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. The original process steps had no process date, so those were set to unknown. Additionally, the source contribution information was virtually non-existent. An attempt was made to add minimal information based on knowledge of the SeaBOSS system. Many of the attributes had no attribute domain values, so this was set to Unrepresentable_Domain, with "Information unavailable from original metadata."Other minor edits were probably performed (title, publisher, publication place, etc.). 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.
