Description:
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the combined single-beam and multibeam echo-sounder data and sidescan-sonar data collected in the vicinity of Edgartown Harbor, Massachusetts. During August 2008 seismic-reflection profiles (Boomer and Chirp) were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.
Purpose:
To release the shot-point navigation data with shot points at the beginning and end of each line and with shot points every 500 shots along the line for the Chirp seismic-reflection data collected along five lines in the vicinity of Edgartown Harbor, offshore Massachusetts in geographic, WGS84.

Shot points at the beginning and end of each line and with shot points every 500 shots along the Chirp seismic acquisition lines collected during the RV Rafael cruise 08034 are included in this data set.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal_Positional_Accuracy_Report: Navigation was by DGPS; positional accuracy to less than 10 m. The 3.5 kHz transducer was mounted on a pole mounted on the starboard side of the RV Rafael 0.6 m below the water surface. The distance from the transducer to the antenna was less than 3 m.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical position was local sea level and there have been no corrections to a datum or for tidal variations. A draft of 0.6 meters was applied to account for the transducer depth.

Process_Description:
High-resolution 3.5 kHz Chirp data were collected August 19-20 aboard the Research Vessel Rafael. The Chirp data were acquired digitally along 16 lines totaling approximately 56.1 km with a Knudsen Engineering Limited (KEL) Chirp 3200 shallow water system and KEL SounderSuite software v1.46. The Chirp trace data recorded with a ping rate of 0.5 seconds for 66 ms with a sample rate of 0.048 ms in standard SEG-Y format.

Process_Description:
The raw SEG-Y data were read into Promax R2003 processing software. Heave compensation data from the Teledyne TSS sensor (mounted on the transducer sidemount pole) were extracted from the SEG-Y headers and were used to apply a static shift to the trace data. A topmute above the sea floor was digitized and applied. An Automatic Gain Control (AGC) with a window length of 5 ms was applied. The processed data were written to a new SEG-Y file.

Process_Description:
A Unix shell script was run that used Seismic Unix 4.0 to read the processed SEG-Y files and extract shot number, horizontal position, year, day, and time of day from the headers. AWK was used to parse the ASCII data, add line and image name fields, and convert position in seconds of arc to decimal degrees. The ASCII file was filtered using Linux "sort" to keep only the unique horizontal positions output to a comma delimited file.

Process_Step:
Process_Description:
A shot-point navigation file that has points at the beginning and end of each line with shot points every 500 shots along the line were created with ArcTools 9.2 Linear Referencing Tools using the shot point and shot line files created for the Chirp dataset. First, the file with unique shot-point positions was used to create a polyline file using an in-house utility, Convert Points to Line v.2. Under ArcToolbox, Linear Referencing Tools, a feature class was created with Create Routes with the polyline file as input and the measure source being length. Next, a polylineM file was created with Calibrate Routes using the route feature class created in the previous step and the unique shot-point position as input. The measure field associated with the polylineM file was Shot. The layer properties of the polylineM file and the Hatch Class definition was set to an interval of 500 (shots) and the end hatches were defined to create the start and end shots of each line. In ArcMap 9.2 a custom tool was created under Linear Referencing commands to convert hatches to graphics. XToolsPro was used to convert graphics to a shapefile. The attributes Line and Shot were added to the event table properties using Locate Features Along Routes. The resulting DBF file was converted to an event feature using Make Route Event Layer using Line as the route identifier and shot as the measure field. The event feature was added to the ArcMap data frame and exported to a shapefile. Finally, the attributes were sorted using line as the primary field and shot as the secondary field using VAC Extras, Table Sort to make sure shot points were in sequential order.
