Abstract: The invention relates to acquiring seismic data from the earth using geophones that are tuned to have differing frequency sensitivity ranges. The differing frequency sensitivity ranges cover a broader effective frequency range so that low frequency energy and high frequency energy are less attenuated in the raw data record. Two separate geophones would be used at the same node and three or more geophones may be used in combination at each node. When three or more geophones are used in combination, each may have a separate but overlapping frequency sensitivity range or two or more of the geophones may have the same frequency range sensitivity.

Abstract: A system includes a subterranean survey data acquisition network and a processor. The network has first nodes that are distributed along a length of the network between a first end of the network and a second end of the network. Each of the first nodes is capable of being either in a state in which the first node is transparent to the network or in a state in which the first node is visible to the network. The processor is adapted to communicate with the closest visible first node relative to the first end, and the processor is adapted to, based on the communication, determine whether the closest visible first node is the closest first node of all of the first nodes relative to the first end.
