地震海洋学作为一门新兴的交叉学科,具有高横向分辨率、短时间内对整个海水剖面进行成像和已有巨量反射地震数据的优势,可望在物理海洋学、海洋地质学领域获得广泛应用,对海洋学发展产生深远影响.本报告较系统地阐述地震海洋学在研究海洋物理过程方面的作用及对海底界面过程方面的探索.

烃类渗漏是海洋环境中广泛分布的自然现象,在全球几乎所有的大陆边缘都有发育.海底烃类渗漏是甲烷从沉积圈进入到水圈和大气圈的重要方式.每年通过此方式释放到海洋及大气中甲烷的量约为20Tg yr-1,约占全球陆地和海洋释放甲烷通量的一半.甲烷是强烈的温室气体,是全球气候变化的一个重要影响因子.因此,准确测定烃类渗漏甲烷的量及认识烃类渗漏流体活动特征对其在全球气候变化中的作用及全球碳循环有着重要的研究意义

针对基于海底全方位长期观测系统对水下声学通信、定位与释放回收技术提出的需求,开展微功耗、远距离、小体积和轻重量的声学通信、定位与释放技术研究,将三者合为一体,在一套声学仪器中实现三种功能,更适用于海底长期观测系统.采用了自适应滤波和瞬时频率方差联合检测的声学信号处理方法,提高了通信和定位信号的检测概率,以及抗海洋环境等噪声干扰和不同信道间的串扰能力.
