Statement

The seismic survey was conducted using a surface-towed IKB Seistec boomer acquisition system, comprising a standard boomer plate combined with a line-in-cone hydrophone receiver arrangement, which is designed to reduce acoustic noise in a shallow water environment (Simpkin and Davis 1993). The system was powered by a 4 kV capacitor discharging power supply unit, and towed on the survey vessel’s aft quarter, in the relatively undisturbed water between the bow wave and the wake. A 200microsecond broadband pulse was produced at the boomer source, at an energy level of 180J and a repetition interval of 500ms. Survey speed was maintained at between 4 and 6kts with GPS positioning yielding location information typically to within 3-8m. Data were recorded in standard SEG-Y format with a record length of 150 ms and sampling interval of 16 micros.
