Geo Space Geophysical Instrumentation Sea Array 3



	Sea Array 3 A Fully Gimballed 3-Component Geophone Package Slim line design Three velocity sensors in one package Fluid filled unit maximizes damping and coupling Wire and bulkheads waterblocked for maximum protection Multiple O-ring seals

Geo Space's Sea Array 3 is a fully gimballed unit that provides precise geophone orientation control in deep water operations. It can be used with all major ocean bottom cable systems. This light weight, slim line package maintains three mutually perpendicular geophones in relative orientation sufficient to permit true 3-component seismic data acquisition, making it ideal for both 3-D and 4-D applications. The Sea Array 3 permits choice of three field-proven geophone models (GS-20DX, GS-30CT, GS-32CT), one vertical and two horizontal, with full rotation of all axes. The fluid filled unit maximizes both damping and coupling. Precision multiple O-ring seals and full water blocked wires assure integrity of the package in ocean bottom service.
