 Remarks:      
   Navigation Streamer depth at 7.0m    
   Recording QC Swell noise seen on all cables approx 10%. Filter delay 5.6ms. Frontsheet Set 4. Gundepth calibrated at atmospheric pressure 1024mB, pressure now 1018mB. SSE functions on TRISOR disabled, GUNPOS block NOT recorded. Slight bend in tail of cables @ sol noise test, gone by sol. All gun DI's erratic d/t swell. Port Array separation a bit low than normal d/t broken gun hanging rope.
