Sercel launches a sparse nodal solution

Sercel is pleased to announce the launch of MicrOBS^NT, an ocean bottom node solution for seismic refraction and reflection surveys.

Equipped with three QuietSeis® MEMS accelerometers and a high performance hydrophone the MicrOBS^NT is a 4C node that is capable of operating in water depths down to 6,000 meters for periods of up to 50 days between battery re-charges.

MicrOBS^NT is ideally suited for hybrid surveys when used in combination with seismic streamers or for sparse OBN surveys.

A key advantage when compared to conventional geophone based OBN, MicrOBS^NT is capable of accurately recording the low frequency signals necessary for velocity modeling.
