Ziel der Reise / Objectives of Cruise:
It was planned to calibrate two digital hydrophone arrays to be used for measuring absolute sound pressure. A vertical one with 161 hydrophones and a towed one with XXX hydrophones. A free drifting (battery powered, calibrated) sound source had to be used. These experiments had to be carried out in deep and calm waters, the Sogne-Fjord in Norway fjord seemed to be optimal. The CTD-profiles were necessary to know about sound velocity profiles an can bei made available, the calibration factors of the two arrays are only for internal use.
