Abstract
The present invention relates to a seismic sensor node and corresponding measuring device for point measurements in seismic surveys of geological subsurface formations, where the sensor node includes a sensor housing with at least one movement sensor, the sensor node comprising a plate structure being adapted to be positioned into the sea bed, the sensor housing having a predetermined outer shape and the plate structure being adapted to receive and essentially enclose the sensor housing for providing acoustic coupling between the plate structure and the sensor housing, and the plate structure having a rotational symmetric structure with a vertical axis. The plate structure comprises a number of radially oriented plates secured together and being adapted to penetrate the sea bed with minimal displacement of the sea bed materials.
