Marsh case for a geophone |
摘要 |
A geophone marsh case, for use in wetlands, contains a geophone. An electric cable delivers geophone signals to the outside world and provides a means for pulling an emplaced geophone from the mud. The cable is anchored to the marsh case both internally and externally in order to preserve the integrity of a water seal that surrounds the cable in the cable entry port of the marsh case.
