This in turn aids in understanding the stratigraphic evolution of the inner-continental shelf, the regional sediment transport system, and the influence of the inner-shelf framework on coastal processes. The grid showing the thickness of Quaternary sediment is an important factor in the framework of the coastal region. Purpose: In 1995, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE), began a program to generate reconnaissance maps of the sea floor offshore of the New York - New Jersey metropolitan area and within the southern Long Island nearshoe area. Our methods include high-resolution sidescan sonar and subbottom profiling techniques, along with surface grab and vibracore sampling to verify the geophysical interpretations. The goal of the investigation is to provide a regional synthesis of the sea-floor environment, to determine regional-scale availability of sand as a resource for beach nourishment programs, and to investigate the role that inner-shelf morphology and geologic framework have in the evolution of the coastal region within the New York Bight Apex and southern Long Island. Maps derived from interpretation of the subbottom profiles show information on the geometry and distribution of the Quaternary sediments and the underlying coastal-plain unconformity. This seismic stratigraphy yields a regional framework on which explanations of present (and past) sediment movement, dispersal, and erosion processes are based.

Shore perpendicular track lines were spaced about 3-4 km apart. Along track samples of the seismic profiles are approximately 1 meter assuming a ship speed of 2 meters/second. The data were downsampled in the along-track direction at an interval of about 30 meters. The horizontal resolution of the gridded data are constrained by the grid cell size of 150 meters. Horizontal interpolation is inherent in the gridding process. Logical_Consistency_Report: The gridded data were checked for consistency by plotting the point data over the the grid and comparing point values with grid cell values. Completeness_Report: The gridded data are limited by horizontal resolution of the grid cell size and spatial distribution of the original point data. Higher resolution data acquisition will likely result in a more detailed representation of sediment distribution and thickness. The data also represent a time interval of the data acquisition. Attributes of elevation of the coastal-plain unconformity change very little over time. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. 99% of the positional data is DGPS. Unless noted, all GPS/DGPS data is referenced to WGS84 (NAD83). The horizontal positioning did not account for source and receiver offsets and offset the GPS antennae and the boomer source and streamer. It is estimated that these offsets could lead to inaccuracies of about 30 m. Because the elevation of the coastal-plain unconformity was calculated by addy Quaternary thickness to a coastal elevation model //www.ngdc.noaa.gov/mgg/coastal/coastal.html), the horizontal accuracy is constrained by the reference to USGS 3-arc-second topographic data (nominal resolution of 90 meters). Offshore hydrographic positioning that is estimated to be 30 m or better closer to shore. Onshore well locations were digitized from paper maps (Sutter and others, 1949). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positioning accuracy of the offshore data is based on the seafloor reference used. coastal-plain elevation in the offshore was determined by adding Quaternary sediment thickness (derived from two-way travel time between the coastal-plain unconformity an the seafloor using an acoustic velocity of 1630 m/s) to a topographic and bathymetric elevation model //www.ngdc.nooa.gov/mgg/coastal/coastal.html). This costal elevation model is referenced to USGS 3-arc-second DEM data that has a vertical accuracy of 1 meter and NOS hydrographic data that has an accuracy of 1/10 of a meter. The entire model is referenced to mean low water or mean or low water. Onshore well elevations were taken from well logs descriptions (Sutter and others, 1949). Finally the Quaternary sediment thickness grid was calculated from the difference of the coastal-plain elevation grid and the coastal elevation model.

Process_Step: Process_Description: Processed SEG-Y seismic data and associated shot navigation data were loaded into Landmark Seisworks interpretation software. The coastal-plain unconformity was digitized along with the seafloor reflector. The difference in two-way travel time between horizons was calculated and converted to meters using an assumed velocity of 1630 m/s. This represents the nearshore Quaternary sediment thickness. These data were exported from seisworks to an ASCII format file. Process_Date: 2001 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Jane F.

The Quaternary sediment thickness grid was addded to the bathymetric grid to yield a grid for the nearshore elevation of the Coastal plain unconformity reference to mean sea water.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Completely changed the title based on an author (Jane Denny) supplied title. Added online links to the publication and data page in the Identification section. Added the standard order section to the Distribution Information, which included providing a link to download the data. The metadata describes both the grid and the contours, but the contours are the only dataset available for download in a zip file from the publication. Downloading the grid would require downloading individual files within folders. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
