Abstract
A nodal geophysical sensing system includes a ground contact sleeve defining an interior space and having at least one feature on an exterior thereof for contacting and compressing ground materials adjacent the exterior. A nodal geophysical sensor having a housing engages at least one feature on the interior space so as to enable acoustic energy transmission between the ground contact sleeve and the housing.
Claims20
A nodal geophysical sensing system, comprising:
- a ground contact sleeve defining an interior space and having at least one feature on an exterior thereof for contacting and compressing ground materials adjacent the exterior, the at least one feature increasing a surface area of the exterior surface beyond that of a substantially smooth, round surface;
- a nodal geophysical sensor enclosed in a separate housing, the separate housing engaging at least one feature on the interior space so as to enable acoustic energy transmission between the ground contact sleeve and the housing;
- and
- wherein the ground contact sleeve comprises a locking mechanism to secure the separate housing within the ground contact sleeve.
1 more element
A method for geophysical surveying, comprising:
- inserting at least one geophysical ground contact sleeve into a ground surface;
- inserting a geophysical sensor disposed in a separate housing into the ground contact sleeve;
- actuating a locking mechanism to secure the separate housing in the ground contact sleeve:
- detecting geophysical signals for a selected length of time;
- removing the geophysical sensor in the separate housing from the ground contact sleeve;
- and
- after a selected period of time, repeating the inserting the sensor into the ground contact sleeve and detecting geophysical signals.
