On almost all the survey lines, sediment profiling was carried out using the ship's DATASONIC DSP-661 Chirp 2 Profiler. Trigger rates varied from 2 to 4 seconds, while chirp pulse length was maintained at 120 ms. Data were displayed on an EPC 9600 and recorded on Magneto-optical disks in SEG-Y format, which will be used off-line for post-processing.
