Multichannel seismic reflection and wide-angle and refraction data acquisition along the Iberia Atlantic Margins

The data acquisition contract was awarded to GECO-PRAKLA and took place in August-September 1993 aboard M/V Geco Sigma. Seismic data was successfully collected along the Cantabrian Margin, Galicia Margin, Iberian Abyssal Plain, the continental platform of Western Iberia, Tagus Abyssal Plain, the Gorringe Bank and Gulf of Cadiz. Data for the 240 km long line IAM-12 was acquired in February 1993 by SEISQUEST vessel of GECO-PRAKLA. The total amount of seismic reflection data collected was 3808.175 km in 19 track lines offshore. Technical specifications of the profiles: Streamer length 4800 m, Number of channels 192, Group interval 25 m, Shotpoint interval 75 m (100 m and 150 m on line IAM-2W), Source 7424 in3 (Record length 25 seconds), Sample rate 4 ms.
