An arrangement for the deployment of seismic sensor units, such as sensor nodes ( 24 ), on the seabed includes a frame structure that is adapted to carry a container ( 11 ) for containment of a data registration unit and additional auxiliary equipment for the sensor node. The arrangement has supports ( 12, 13 ) that can rest against the seabed, and an attachment means ( 17 ) for a lifting hook, for raising and lowering by means of a crane. There is a holder ( 20 ) for the sensor node ( 24 ) that can be positioned on the seabed and which is connected to the container through a signal cable ( 32 ). A releasable attachment means ( 22 ) holds the sensor node ( 24 ) in a downwardly extending position with respect to the supports ( 12, 13 ). The attachment means ( 22 ) is located with a horizontal distance from the container ( 11 ). A latch mechanism ( 25 ) for the attachment means ( 22 ) is adapted to release the sensor node ( 24 ).
