Description:
Abstract:
These data orginate from interpretations of seismic reflection profile data. The derivative data are in a grid format and are intended to represent the thickness and distribution of Pleistocene deposits throughout the inner-continental shelf within the New York Bight. The gridded Pleistocene thickness is helpful 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 thickness of Pleistocene 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.

Data_Set_Credit:
This data set resulted from a cooperative with the US Geological Survey and the US Army Corps of Engineers.
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
These data are derived from grids generated from interpretation of 2D seismic reflection profiles. The horizontal resolution of the gridded data are constrained by the grid cell size of 100 meters. Horizontal interpolation is inherent in the gridding process.
Logical_Consistency_Report:
The gridded data were checked for consistency by plotting the Holocene and Quaternary Isopach to ensure that the grid values represent accurate Pleistocene thicknesses, given the aforementioned Isopachs as reference.
Completeness_Report:
The gridded data are limited by horizontal resolution of the grid cell size and spatial distribution of the original point data used to generate the two reference grids: Holocene and Quaternary Isopach. 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 may and probably do change with 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). Tow fish (sidescan) position was corrected for layback using acoustic slant range measurements and fish pressure depth measurements, otherwise corrected for layback by manual inputs for slant range and fish depth. Accuracy for slant range varies with distance from the ship and the noise conditions in the water, nominally up to 30 meters is better than 2 meters. Pressure depth is accurate to .1 meter. Manual slant range can use cable out measurements or estimates based on data processing results.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical positioning is not necessary to quantify thickness of sediment data. The data are referenced to the distance between the sea floor and the base of the modern sand using an acoustic velocity of 1630 m/s.

The Quaternary and Holocene Isopach (gridded data) were used to generate the Pleistocene Isopach. Pleistocene thickness was represented by the difference between the Quaternary and Holocene sediment thickness.
Process_Step:
Process_Description:
The difference between the Quaternary and Holocene Isopachs was used to generate the Pleistocene Isopach within Dynamic Graphics Inc., EarthVision surface modelling software. The resultant grid has a grid cell size of 100, yeilding a grid size of 1007 rows and 1854 columns. The grid was exported as an ASCII raster format file.

Process_Description:
The exported ASCII Pleistocene thickness grid file from EarthVision was edited to create an ASCII grid file suitable for import to ArcView software. The order of rows were flipped, so that the file begins with the lower row, left column and ends with the upper row right column. An ArcView header that descibes the lower left origin of the grid, the grid cell size, the number of rows and columns, and the null value used (-9999).

Process_Description:
Contour data were generated from the Pleistocene Isopach Gridded data at a 5 meter contour interval within EarthVision. These data were exported and converted to an ESRI generate format. The contour interval associated with each contour was saved as an ASCII file and read into ArcView in table format. The generate file was converted to a vector shapefile. The table and attritube table of the contour shapefile were joined based on unique contour IDs. The attribute table was then editted to include the associated contour value with each contour line, and the join was removed. These contour data are stored in the Geographic Coordinate System (decimal degrees, WGSir Ellipsoid).

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. 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.
