Geological Survey 1 CD-ROM http://pubs.usgs.gov/of/2003/of03-001/ A study was made of the composition, grain-size distribution, and organic content of grab samples collected from Boston Harbor. In general, the coarsest mean sizes occur in the channels scoured by dredging or tidal action, and the finest in areas where no dredging has occurred and where tidal velocities are at a minimum. The purpose of this data layer is to release a digital version of the grain-size data released in the publication Mencher et al.

All attributes were entered and checked by compilers in a consistent manner. No additional checks for topological consistency were performed on this data. Sample locations, mean grain size, and station identifiers are provided for 159 stations. No navigational methods are provided in the original report. Horizontal accuracy is unknown. Tides average about 3 m. Ely Mencher R.A. Copeland H.

Interpretive maps were transposed into tabular data and subsequently converted into an ASCII file. The navigation was digitized from maps in the original paper. The source information was manually entered into digital form and was imported from an ASCII text file to an ArcView table. The table was later converted to and event theme and saved as the final shapefile. mencher.txt 20020911 mencher.shp mencher.dbf mencher.shx Lawrence J.

Woods Hole MA 02543-1598 USA (508) 548-8700 x2314 (508) 457-2310 lpope@usgs.gov 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.). Minor fixes to the attribute format for some attributes was needed. 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. 20151202 U.S. Geological Survey VeeAnn A. Cross Marine Geologist mailing and physical address
