Description:
Abstract:
These data contain backscatter intensity obtained from sidescan sonar. The sidescan-sonar data were digitally mosaicked to provide a base suitable for use in a geographic information system (GIS) of the New York Bight.
Purpose:
These data are included in this publication to provide bathymetry and backscatter intensity for maps showing the locations of images and samples obtained in the New York Bight.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: These data are internally consistent and accurate.
Logical_Consistency_Report:
These data are logically consistent; they were acquired with a Datasoncis SIS-1000 sidescan-sonar system, and processed following an identical procedure.
Completeness_Report: These data are 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). Slant-range distance is recorded between the sidescan-sonar tow vehicle and a sidemount rigged with an acoustic transponder. Offset between the sidemount and GPS antennae is measured. Basic trigonomic calculations use the slant-range offset to calculate a 'fish' (tow-vehicle) navigation. An assumption in these calculations is that the tow-vehicle is traveling directly behind the vessel; movement to port or starboard is not accounted for within 'fish' navigation. Thus, the horizontal accuarcy of the sidescan-sonar tow-vehicle is +/- 15 meters.

These are the raw QMIPS sidescan-sonar data that were used to generate the sidescan-sonar mosaic.
Process_Step:
Process_Description:
The sidescan-sonar data were acquired with a Datasonics SIS 1000 CHIRP sonar system, which operates in a frequency range of 100 - 120 kHz. The sidescan-sonar imagery of the New York Bight region is comprised of data acquired on seven geophysical cruises operated by the USGS during 1995 - 1998.

All sidescan-sonar data were logged digitally at a sample rate resulting in a 0.18-m pixel size in the across-track direction and approximately 0.14-m in the along-track direction following the methodology outlined in Danforth and others (1991). A median filtering routine (Malinverno and others, 1990) was applied to the sidescan-sonar data to remove speckle noise, resulting in a 0.73-m pixel size. The data for each survey were further processed and digitally mosaicked using PCI Geomatica Software and procedures described in Danforth and others (1991), Danforth (1997), and Paskevich (1992) resulting in an enhanced, geographically correct, sidescan-sonar mosaic with 4 meters/pixel resolution. The seven individual images were then mosaicked to form one composite sidescan-sonar image for the New York Bight region. The composite mosaic has a resolution of 16 meters/pixel. The composite mosaic was exported as a TIFF image, with an associated ESRI world file.

Process_Description:
The TIFF image (sonar.tif) was compressed using LizardTech, MrSID GeoSpatial Encoder 1.3.1. This software compresses the image at a specified ratio, which is 20:1 by default. An associated sdw file accompanies the .sid file. The .sdw is an ESRI world file for the given .sid image file. In order to view these data within ArcView, the MrSID Image Support extension must be loaded. Once, the extension is loaded, the .sid image file can be loaded into ArcView as an Image.
