Streamer

We used UGBO's Teledyne Mod. 40508 programmable array, with Group Interval set to 25 mt. Total number of active Channels was 48, plus stretch sections at the head and at the tail. The offset of the first active to source varied from 142 to 158 m. From the Sea-Mac Mod. 3530EHS-50 winch, seismic channels and control lines were run to a Kalamos Locate Type M-4 interface. The depth of the streamer ranged from 6 to 10 m, and was controlled by a group of 8 Digicourse Mod. 5010 Cable Levelers, three of which were equipped with pressure controlled safety buoys, controlled by an FSK modem using Digicourse Digiscan Software. From the M-4 ouput cable connector (configured for a DFSV) the 48 seismic channels were run to the seismograph by a jumper cable. In addition, we prepared another jumper which could connect the deck leaders directly to the seismograph.
