Abstract

Features of the tomography of the marine crust are described, based on the use of coastal laser strainmeters and broadband low-frequency underwater acoustic projectors. This approach is useful in studying the structure and composition of the marine crust in shelf areas, including ones covered with ice without destroying it. Numerous experimental studies have established that at sea depths equal to or less than half the length of a hydroacoustic wave generated by low-frequency underwater acoustic projectors, the hydroacoustic energy is mainly transformed into Rayleigh-type surface waves that radiate through the bottom on the hydroacoustic source–coast path.

基于沿海激光应变仪和水下声投影仪的海底层析成像

摘要

基于沿海激光应变仪和宽带低频水下声学投影仪的使用，对海壳层析成像的特征进行了描述。该方法可用于研究架子区域的海底结构和组成，包括被冰覆盖而不会破坏的区域。许多实验研究已经确定，在等于或小于低频水下声波投影仪产生的水声波长度一半的海深处，水声能量主要转换为瑞利型表面波，该表面波辐射通过水声波的底部。源－海岸路径。
