Experimental Determination of Properties of the Scholte Wave in the Bottom of the North Sea

Part of the NATO Conference Series book series (NATOCS, volume 5)


An experiment was carried out in the North Sea with the objective of exciting the Scholte wave and investigating its propagation. Shots of 3 and 10 kg TNT at the sea bottom provided the seismic source. 3-component seismometers were set up at distances between 0.8 and 1.7 km from the source. The seismic signal was transmitted by radio to the recording ship. An elastic wave with a propagation velocity of 111 m/s was detected. The hodograph shows a vertical, polarized, retrograde ellipse. The observed frequencies are in the range 4.5 ± 1 Hz. The vertical component accounts for around 64% of the elastic energy as measured at the sediment/water interface. After subtraction of the geometric attenuation (Er prop. 1/R), it was possible to determine the order of magnitude of attenuation of the Scholte wave (7.10-3 dB/m).
