Abstract

During the past five years several single-channel water-borne shallow seismic surveys have been carried out using a special instrument called IKB SeistecTM. One of the main advantages of the SeistecTM profiler is that the source (a boomer) and the receiver (a line-in-cone group of piesoelectric hydrophones) are mounted on the same catamaran body. This way a fix offset is ensured during the whole time of operation. The 90° aperture focusing cone around the hydrophones has a very good vertical selectivity and almost completely eliminates direct waves and side reflections. In addition, as the water is almost still inside the cone no noise is created by the friction between the hydrophones and the water. Therefore signal-to-noise ratio of the SeistecTM records is usually higher than for conventional streamer records.
