For this dataset a 150 cinch generator-injector airgun provided active source signals up 300 Hz. The streamer comprises a 100 m long tow cable, a 20 m long stretch section and 19 active sections of 12.5 m length. Each active section of the streamer holds 8 channels at 1.5625 m distance. Depth control of the streamer was provided through three active birds, one attached on the stretch section, one attached to a 1.5625 m bird section between active section 11 & 12 (causing one dead trace count) and a third behind active section 19 Water velocity was used to provide normal-moveout-corrected, stacked and migrated seismic profiles. Aim of the seismic experiment was to provide high-resolution images of gas migration pathways and gas hydrate accumulations at Honeycomb ridge.
