This paper describes the design and operation of a 3D survey in an area containing a number of novel and interesting geophysical problems. Special data were acquired to enable the selection of a suitable configuration of source, streamer and positioning equipment to meet stringent spatial and temporal sampling requirements. Low signal to noise ratios in the area prohibited the loss of stack fold inherent in multiple source systems. The survey was performed using a single source array and six 600 m streamers. To provide high positioning accuracy, the navigation system included two radio positioning systems, differential GPS and a network of acoustic ranging devices.
