dc.description.abstract	Surface wave spectra have been measured in the North Sea simultaneously with acoustic investigations using explosive and CW sources. The goal of these experiments was to determine the influence of surface waves to low-frequency sound propagation. Vertical chains of hydrophones in different distances from the source are used to get the attenuation of the single modes. In order to resolve the influence of the s urface, the experiments were carried out during different sea states. Doppler-spectra from first measurements with a 500 Hz source and one receiving hydrophone are presented.
