 The Sea Array 4 is a fully gimballed unit that maintains three
mutually perpendicular geophones (one vertical, two horizontal) with full
orientation in all axes, along with one hydrophone. It can be used with all
major ocean bottom cable systems for 3-component and 4-component seismic data
acquisition.
The fluid-filled unit maximizes damping and coupling. Multiple
precision o-rings and full water-blocked wires and assembly assure integrity of
the package at depths to 2,000 meters, but is limited to the operational depth
of the hydrophone unit selected.
The slim line unit accommodates a choice of
four field-proven geophones: the economical GS-20DX, the close tolerance
GS-30CT, and GS032CT, or the X-Phone which provides the industry's tightest
tolerances, lowest distortion and the highest spurious response in a single
unit. Hydrophone selection from one meter to 2,000 meters.
