Abstract: A seismic sensor detects a characteristic of a medium during a seismic survey. The seismic sensor includes a casing; a magnet located inside the casing; a coil assembly located inside the casing, wherein the coil assembly moves relative to the magnet; and a temperature-sensitive device connected to terminals of the coil assembly and configured to improve the damping. The magnet and the coil assembly produce some intrinsic damping and the additional damping introduced by the temperature-sensitive device is selected to counterbalance the temperature-dependent intrinsic damping so that a phase of a recorded seismic signal is compensated for temperature induced magnetic field changes.

Abstract: It is proposed a method for providing synchronization in a data acquisition system including a plurality of acquisition units. A given acquisition unit of the plurality carries out the following steps: receiving a packet from another device of the data acquisition system; extracting a synchronization accuracy information and a reference clock information from the received packet; obtaining a first reference clock as a function of the extracted reference clock information; if the extracted synchronization accuracy information indicates a better synchronization accuracy than a current synchronization accuracy information associated to the given acquisition unit: taking the obtained first reference clock as a selected reference clock and updating the current synchronization accuracy information to indicate a lower synchronization accuracy than the extracted synchronization accuracy information.
