Book excerpt: The Atlantic Coast of New York Monitoring Program, a cooperative effort between the U.S. Army Engineer District, New York, New York State Department of State, and New York Sea Grant, was initiated in 1995 to collect and assemble data on coastal processes along the south shore of Long Island. The program sponsored the collection of aerial photography and cross-shore topographic profiles from Coney Island to Montauk Point. For the purposes of organizing and classifying the profile data, the south shore has been divided into eight reaches: Coney Island, Rockaway Beach, Long Beach, Jones Beach, Fire Island, Westhampton, Ponds, and Montauk. The total number of profiles assembled in the ACNYMP databases is close to 3,000, of which 2,000 were long lines, 900 were short (wading depth), and less than three percent were rejected after quality inspections. The bulk of the profiles date from 1995 and 2001, with some earlier surveys included for the Coney Island and Rockaway reaches. Quality control and verification of the profiles proved to be a major effort, evolving into a five-part process: (a) Initial inspection at New York District; (b) Detailed plotting and screening at the Coastal and Hydraulics Laboratory (CHL) in Vicksburg; (c) Joint inspection of a CD-based display and viewing tool developed by a contractor; (d) Developing a consensus on questionable profiles at a workshop in 2001; and (e) final adjustments and corrections at CHL. These procedures will be used for future data collected on Long Island.
