Single Channel Streamer Details from Cruise Report:"The SCS streamer is configured with a 188 m leader, a 25 m stretch section, and four active sections totaling 137 m (12.5 m, 25 m, 50 m and 50 m). The data are recorded on DMS2000 data tapes on channels 4 (raw data) and channel 5 (attenuated by a factor of 20 across the entire frequency band of 0-160 Hz) (note: a total of 8 channels are recorded on the data tape, channels 1-3 and 6-8 are dummy channels)." NOTE: We assume the 4 streamer sections were summed before being recorded. There are actually 12 traces for each single channel line on tape
