Description:

Abstract:

The New York Bight fault (Hutchinson, 1984) was clearly evident within the high-resolution seismic records acquired with a CHIRP, boomer, and 15 cubic inch water gun systems. This fault was mapped from these data. Thus, yeilding a more complete picture of the inner-shelf geologic framework of the area.

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_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

These data are derived from 2D seismic reflection profiles that are spaced approximately 1.3 km apart in the cross track-direction. 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.

Logical_Consistency_Report:

The New York Bight Fault was mapped from high-resolution CHIRP, boomer, and 15 cubic inch water gun seismic systems. These data were checked for consistency be comparing mapped locations to those reported in the literature (Hutchinson, 1984).

Completeness_Report: complete

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.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Vertical positioning accuracy of the offshore data is based on the seafloor reference used.

The well log data compiled within this thesis were used to generate a gridded data set of the depth to coastal-plain Unconformity and Quaternary thickness onshore Long Island, NY.

Process_Step:

Process_Description:

As part of the MS Thesis, the location of the New York Bight fault was mapped from high-resolution seismic records (15 cubic inch water-gun). The location of the fault was saved as a digital ASCII file listing x,y (eastings and northings). The coordinates were transformed from UTM, Zone18, WGS84 to Geographic, Coordinate System, WGS84 datum. These ASCII x,y data were imported into ArcView 3.2 as a table. They were then coverted into an ESRI point shapefile.
