Method for compensating marine geophysical sensor measurements for effects of streamer elongation

摘要

A method for determining a longitudinal position of at least one geophysical sensor on a towed marine streamer includes measuring a parameter related to tension at least one position along the streamer. A change in length of the streamer is determined using the measured parameter. The longitudinal position of the at least one sensor is determined. A marine streamer includes at least one geophysical sensor and at least one tension sensor capable of measuring a parameter related to axial tension.
