C-01 AN EVALUATION OF PEAK AND BUBBLE TUNING IN SUB-BASALT IMAGING - MODELLING AND RESULTS Summary 1 Z. LUNNON 1 P. CHRISTIE 2 and R. WHITE 1 1 Bullard Labs Madingley Road Cambridge CB3 0EZ UK 2 Schlumberger Cambridge Research As part of the iSIMM project (White et al. 2002) a 6 360 in 3 airgun source array was used to shoot twice a deep seismic profile into a 380 km array of Ocean Bottom Seismometers (OBS) east of the Faroe Islands. The first pass used peak tuning and the second used bubble tuning with other source parameters constant. The
