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.
To release a polyline data set for the Chirp seismic-reflection data collected along five lines in the vicinity of Edgartown Harbor, offshore Massachusetts. The Chirp data were collected to interpret the shallower stratigraphy beneath Edgartown Harbor.

All attributes were checked in a consistent manner.
No additional checks for consistency were performed on this data.
All available trackline data along Chirp seismic acquisition lines collected during the RV Rafael cruise 08034 is included in this data set except for the first two files were omitted from the processing. These files only contain a few seconds of data.
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 on the starboard side of the RV Rafael 0.6 m below the water surface.
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.

The original Chirp navigation data.
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 v1.26 software. 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.

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 AGC with a window length of 5 ms was applied. The processed data were written to a new SEG-Y file.

A Unix shell script was run that used Seismic Unix 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.

Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). 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.
