A seismic data collection unit having multiple separate geophones/geophone packages positioned in a housing wherein the geophones are offset from a vertical axis so that summing of the geophones' respective outputs minimizes certain noise in the unit's output. Specifically, the offset geophones are physically positioned or mathematically configured so as to be symmetrical about a selected vertical axis in order to cancel out certain noise in a seismic signal. The particular placement of the geophones within the housing is preferably selected so that th...
What is claimed is: 1. A seismic data collection unit comprising: a. a water tight case having a wall defining an internal compartment, wherein the case is substantially symmetrical about an axis of symmetry so as to define a center of gravity for said case along said axis; b. at least two geophones disposed within said case, wherein each geophone is offset from said axis by a first offset distance and each geophone is offset from one another; c. a clock disposed within said case; d. a power source disposed within said case; and e. a seismic data record...
