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 multibeam echo-sounder 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 Chirp seismic profiles collected to ground-truth acoustic data (single-beam and multibeam bathymetry and sidescan sonar imagery) collected during NOAA hydrographic survey H11346. The Chirp data were collected to interpret the shallower stratigraphy beneath Edgartown Harbor.

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 Sounder Suite 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.

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 seas 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.

The seismic data were collected during USGS survey 08034, conducted August 18-20, 2008. Each profile is available as a binary file in Society of Exploration Geophysicists SEG-Y rev 1 format and JPEG image format. A SEG-Y file consists of 1) a 3200-byte file identification record of EBCDIC encoded general information; 2) a 400-byte binary record with information such as sample rate and record length specific to the data set; and 3) multiple records, one seismic reflection trace per record. Each trace record is preceded by a 240-byte "trace header" containing information such as trace number and acquisition day and time specific to each trace. The trace data are represented as a time series of unitless 32-bit IEEE real numbers proportional to the reflection coefficient. The SEG-Y file is useful only if you have access to specialized software designed to process and display seismic reflection data.
