METHOD INVOLVING MOVING ICE BODIES AS A CARRIER FOR SURVEYING A REGION OF THE EARTH

摘要

In order to perform a passive survey, sensors (5, 8) for obtaining data relating to the structure of the region (1) are deployed on ice bodies (4) which move as a result of natural drift. The sensors (5, 8) are used to obtain data at different locations resulting from movement of the ice bodies (4) with respect to the region (1). The sensors (5, 8) may be seismometers which respond to ambient noise, for example resulting from cracking or colliding of the ice bodies (4, 24).
