   Recording QC Filter delay 5.6ms. Frontsheet Set 4. Gundepth calibrated at atmospheric pressure 1017mB, pressure now 1025mB. Turn noise on BOL noise record due to short run to avoid the shallows. SSE functions on TRISOR disabled, GUNPOS block NOT recorded. Gun DI's slightly erratic d/t swell. Occ swell noise seen on all cables. Birds on Str 1 occasionally lost comms. STR 1 NTBP d/t drop out and lost bird data.
