摘要：

详细介绍了最新研制的便携式海底沉积声学原位测量系统的工作原理和结构组成。与基于液压驱动的海底沉积声学原位测量系统相比, 该系统操作简单, 轻便灵活, 易于吊放。2010年中国科学院南海海洋研究所“实验3”号科考船南海开放航次应用该系统在南海北部开展了海底沉积声学原位测量, 首次获得该海区海底沉积物声速和声衰减系数原位测量数据。将原位测量声速与实验室测量声速进行了对比分析, 结果表明二者存在明显差异, 从而表明温度和压力等环境参数对沉积物声速具有重要影响。

Abstract:

The working principle and components of a newly developed portable seafloor sediment acoustic in situ measurement system were introduced in detail. Comparing to the sediment acoustic in situ measurement system based on hydraulically-driven penetration, the portable in situ system is flexible and easy to operate, more convenient for deployment and recovery. The acoustic properties of seafloor sediments in the northern South China Sea were measured using the portable in situ system during the 2010 South China Sea Open Cruise by R/V “Shiyan 3”. The in situ sound speeds and attenuation coefficients of seafloor sediments were obtained in this area for the first time. A comparison of the sound speeds measured by the portable in situ system and laboratorial equipment was carried out. The result indicates that there was distinct difference between the in situ and the laboratorial sound speeds, and the difference indicates environmental parameters, such as temperature and hydrostatic pressure, have significant influences on sound speeds of sediments.

Key words: seafloor sediment, sound speed, sound attenuation coefficient, in-situ measurement, South China Sea
