Locations of Dredged Material Placed in the Historic Area Remediation Site Offshore of New York 1996-2000, USGS OFR 00-503

The purpose of this project is to map the surficial geology of the sea
floor of Historic Area Remediation Site (HARS) and changes in
surficial characteristics over time. This GIS project presents
multibeam and other data in a digital format for analysis and display
by scientists, policy makers, managers and the general public.

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.
