US Seismic Systems Inc. built and shipped an ultra-high sensitivity, fiber optic-based marine seismic array for oil and gas exploration.

The system was purchased by an international service provider and is intended for use as a marine array to help collect and interpret data in the hostile environment of deep sea oil and gas operations.

The contract, valued at more than $800,000, is the first completion of a cycle that starts with testing, evaluating and finally sales and shipment.
