【摘要】

：

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.

基于分角距角度响应特征的多波束海底底质分类方法

对海底沉积物底质分类可以了解海底沉积物的不同颗粒大小、类型在海底的分布特征,进而可研究海底沉积物的物源和沉积环境等,是现今海洋工程、海洋地质和海洋环境研究的重要信息.用声呐技术进行底质分类具有工作效率高、资料连续等优点,因而是对传统的海洋地质调查手段开展底质分类技术的一种重要补充.传统的基于角度响应曲线特征分类是多波束声呐海底分类技术中的一个重要方法,但会出现分辨率较低等问题,为此,本文在其基础上

南海北部莺歌海岭头岬烃类渗漏系统原位观测研究

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
