IN SITU SYSTEM FOR MEASURING SOUND WAVE TRANSMISSION VELOCITY FOR SURVEY OF SEABED GEOLOGY

摘要

The present invention relates to an in-situ system for measuring a sound wave transmission velocity for surveying seabed geology. To apprehend the characteristics of marine sediments, the in-situ system comprises: a sound wave signal measurement device placed on the seabed for directly measuring sound wave signals regarding the seabed and additional information; and a sound wave transmission velocity calculation device capable of calculating the sound wave transmission velocity by utilizing the sound wave signal and additional information measured by the sound wave signal measurement device. Thereby, the in-situ system for measuring a sound wave transmission velocity for surveying seabed geology is capable of preventing errors caused by differences in temperatures and pressures during the measurement of the sound wave transmission velocity in a laboratory environment, to the fullest degree.
