Portable HiRes Multi-Channel Seismic Shot Data from the Long Island Shelf acquired during the R/V Endeavor expedition EN370 (2002)

This data set was acquired with the LDEO Portable HiRes Multi-Channel Seismic system during R/V Endeavor expedition EN370 conducted in 2002 (Chief Scientist: Dr. Gregory Mountain; Investigators: Dr. Gregory Mountain, Dr. Nicholas Christie-Blick, and Dr. Cecilia McHugh). These data files are of SEGY format and include Multi-Channel Reflection Seismic shot data that have not been processed. Data were acquired as part of the project: Hi-Res MCS, CHIRP and side-scan sonar study of NY/NJ margins, and funding was provided by NSF grants: OCE01-19019 and OCE02-24767. These data are cited by McHugh et al., 2010.

Record Length: 3.0 seconds for line 6

Record Length: 2.8 seconds for lines 8,10

Record Length: 2.6 seconds for lines 12,14,16,22,1,24,26,28,32,34,30,33,31.1

ACQ001 and ACQ002

Number of Channels: Channels 1-48 were recorded, channels 1-5 were not usable

Source to Near Channel: Channel 6 (the near channel) and the source were both 52 meters from the antenna with a lateral distance between them of ~5.5 meters. Recorded channels 25-48 were actually channels 48-25 so either they must be renumbered or the offsets calculated accordingly.
