What does this data set describe?

    Title:
    Locations of dredged material placed in the Historic Area Remediation Site offshore of New York 1996-2000
    Abstract:
    This data set includes the location and volume of material placed on the sea floor in the Historic Area Remediation Site between November 1996 and April 2000, extracted from records maintained by the U.S. Army Corps of Engineers. These data are maintained in a system called DAN-NY (Disposal Analysis System-NY). DAN-NY includes data from Inspector Logs (data recorded by inspectors on the barges), and more recently data acquired by NYDISS (New York Disposal Surveillance System). The NYDISS automatically records the location of the barge when placement begins and ends. For material placed between November 1996 and November 1998, the plotted locations are from Inspector Logs. For the material placed between November 1998 and April 2000, the placement location was determined by NYDISS. This Open-File Report utilizes the location (latitude and longitude), date of placement, and volume of material in the scow from these data bases.

  8. What are the components of this data set?
    harsdmpbtwn1_2.shp (An Arcview shapefile with point topology)
    Location of material placementbetween 2/18/1997 and 4/14/1998 (following the the November 1996 multibeam survey of the HARS and before the October 1998 multibeam survey of the HARS).
    harsdmpbtwn2_3.shp (An Arcview shapefile with point topology)
    Location of material placement between 11/171998 and 4/20/2000 ( following the October 1998 multibeam survey of the HARS and before the April 2000 multibeam survey of the HARS). During April only the locations where placement occurred after the area was surveyed are shown.
    harscapping.shp (An Arcview shapefile with line topology)
    Tracklines showing the position of the tug as capping material was released from the scow. This area was covered with a minimum of one meter of sand (approximately 2.4 million cubic yards or 1.83 million cubic meters) dredged from the Ambrose entrance channel to New York harbor. This sand was slowly released from scows and/or hopper dredges along ship tracks oriented north to south. Capping was completed in February 1998.
