Abstract
The present application relates to a seismic sensor coupling device and method. Translational data in a first direction is measured by particle motion sensors contained in an elongated housing of a sensor device provided at an earth surface. The particle motion sensors are spaced apart along a second, different direction along a longitudinal axis of the elongated housing. Rotation data around a third direction is computed based at least in part on computing a gradient of the translational data with respect to the second direction. Coupling of the sensor to the earth and features related thereto are addressed in the present application.
