Summary

The Atlantic Beach artificial reef, located on the sea floor 3 nautical miles south of Atlantic Beach, New York in about 20 meters water depth, was built to create habitat for marine life. The reef was originally created by placing heavy materials such as tires, automobile bodies and other vehicles, barges, and rock from a dredging project on the sea floor. 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 [...]

Purpose

The navigation polyline shapefile shows the track followed by the Canadian Coast Guard ship Frederick G. Creed in the 2000 survey of the Atlantic Beach 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 east-west parallel to the local bathymetry.
