Summary

The Sandy Hook artificial reef, located on the sea floor offshore of Sandy Hook, New Jersey was built to create habitat for marine life. The reef was created by the placement of heavy materials on the sea floor; ninety-five percent of the material in the Sandy Hook reef is rock. In 2000, the U.S. Geological Survey surveyed the area using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard (CCG) ship Frederick G. Creed. The purpose of this multibeam survey, done in cooperation with the U.S. Army Corps of Engineers when the Creed was in the New York region in April 2000, was to map the bathymetry and backscatter intensity of the sea floor in the area of the Sandy Hook artificial reef. The collected data from this [...]

Purpose

The navigation polyline shapefile shows the track followed by the Canadian Coast Guard ship Frederick G. Creed in the 2000 survey of the Sandy Hook artificial reef. The shapefile can be used to identify line spacing, trackline orientation, and the location of data collection. The attributes record the latitude, longitude, date, and time at the start of each line. The tracklines run approximately north-south parallel to the local bathymetry.
