Title:
Sample and video stations located in the Stellwagen Bank National Marine Sanctuary region (sbnmsallsta.shp)
Abstract:
This data set contains point locations for data stations in the Stellwagen Bank National Marine Sanctuary Region off Boston, Massachusetts, an area of approximately 1100 nautical square miles. The Stellwagen Bank NMS Mapping Project is designed to provide detailed maps of the Stellwagen Bank region's environments and habitats and the first complete multibeam topographic and sea floor characterization maps of a significant region of the shallow EEZ. Stations represent the location of a sediment sample and/or the end of a video transect. Coordinated Universal Time (UTC) was recorded for each station location; latitude and longitude were later extracted from a GPS navigational log file using this time.

Why was the data set created?

Development of interpretive seabed maps, sea floor imagery, and a GIS database that are accessible to scientists, policymakers, managers, and the general public.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: unknown (process 1 of 2)
    Station location point data were created using latitude and longitude from a GPS navigational log collected during research cruises from 1993 through 2004. Data sources produced in this process:
    • sbnmsallsta.shp
    • sbnmsallsta.dbf
    • sbnmsallsta.shx
    Date: 08-Sep-2021 (process 2 of 2)
    The metadata was edited to remove errors as well as update some information. Edits include modifying the title to move the dataset name to the end of the title, adding the DOI link in the identification section, added the suggested citation, added supplemental information with link to the related field activity pages on CMGDS, added the USGS Thesaurus keywords, added keywords section with USGS persistent identifier as theme keyword, removed an unecessary process step about copying the dataset, replaced distribution liability with FSP statement, used a generic email address in metadata. The metadata date (20050822), but not the contact (except email and contact instructions) was updated. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. Original edits on 20210816. An additional author name fix on 20210908. Person who carried out this activity:
