Title:
Location and sediment texture information of surficial sediment samples collected within the New York Bight by the U.S. Geological Survey, 1995 - 1999 (Esri point shapefile, Geographic, WGS84)
Abstract:
A better understanding of sediment dynamics in coastal areas can be attained by mapping the surface sediment distribution and subsurface stratigraphy of the lower shoreface and inner-continental shelf. In 1995, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, began a program to produce geologic maps of the sea floor throughout the New York Bight Apex using high-resolution sidescan-sonar, subbottom profiling, and sediment sampling techniques. The goals of the investigation are to investigate the role that inner-shelf morphology and geologic framework play in the evolution of the coastal region.

Why was the data set created?

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.

  2. How were the data generated, processed, and modified?
    Date: 2000 (process 1 of 7)
    The textural data were acquired from the USGS sediment analysis laboratory as an ASCII file. These data were then imported, as a table, into ArcView 3.2. The tabular data were then converted into an ArcView 3.2 shapefile. All of the sediment textural information is contained within the ArcView shapefile as attributes.

    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 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. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    Unknown
  2. How accurate are the geographic locations?
    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). Offsets were not accounted for GPS antenna to sampler. Therefore, horizontal accuracy for grab samples is assumed to be within +/- 20 meters.
  3. How accurate are the heights or depths?
    Unknown
  4. Where are the gaps in the data? What is missing?
    These data are known to be complete.
  5. How consistent are the relationships among the observations, including topology?
    These data are considered to be logically consistent.
