在国内外海洋地震勘探中,特别是浅海勘探中,地震记录上经常遇到一种频率和视速度都比较低的规则干扰波,即本文所要研究的海底波。例如在南美洲的马拉开波湖(称为mud波)、美国的赫德森河(称为grandfather波)、苏联的阿普歇伦半岛北岸海域以及我国的海洋地震勘探中,都曾发现过这种干扰波。而且在国外地震勘探中,对这种干扰波曾做过一些试验研究工作,指出:其频率和视速度都比较低,频率在5—30周之间,视速度为400—800米/秒,具有波散现象,并且指出这种波的能量与海底性质有关,通常在淤泥质海底情况下最容易出现这种波。目前国内外通认为这种波是海洋地震
In marine seismic exploration at home and abroad, especially in shallow sea exploration, the seismic records often encounter a regular interference wave with low frequency and apparent velocity, which is the submarine wave to be studied in this paper. For example, it has been discovered in Lake Maracaibo (called mud wave) in South America, the Hudson River (called grandfather wave) in the United States, the northern shore of the Apulian Peninsula in the Soviet Union, and marine seismic exploration in our country This interference wave. And in foreign seismic exploration, this interference wave has done some experimental research, pointed out: the frequency and apparent velocity are relatively low, the frequency of 5-30 weeks, the apparent velocity of 400-800 m / s, It has the wave-scattering phenomenon and points out that the energy of this wave is related to the nature of the seafloor. This wave is most likely to occur in the case of the muddy seafloor. At present, the waves at home and abroad are considered as marine earthquakes
