Abstract:
1. An apparatus for acquiring seismic data over a loose surface, the apparatus comprising: a housing capable of moving on the loose surface, the housing having an opening configured at a bottom surface of the housing; a seismic sensing unit configured within the housing at an angle with respect to a horizontal plane, wherein the seismic sensing unit is operable to retractably move towards and away from the opening within the housing, whereby in response to moving towards the opening, the seismic sensing unit establishes contact with the loose surface for acquiring the seismic data; a supporting unit removably attached to the bottom portion of the housing, the supporting unit having the seismic sensing unit moveably mounted thereon; and a drive channel configured on the supporting unit, wherein the seismic sensing unit is movably mounted on the drive channel for facilitating the retractable movement of the seismic sensing unit.
