简介：这个工作的主要目的是由在Karatungk附近获得浅速度结构理解矿物质的分发()区域。数据被一个更稠密的数组在与4.5Hz垂直地震检波器部署一张便携测震表在2009获得。所有P波浪到达时间与Akaike信息标准自动地被拣，然后由短接收装置的几何学交互地检查了manmachine。为本地活跃来源的tomographic倒置的数据库包含4从96射击和三石场强风的241P波浪到达时间读物。棋盘测试瞄准了检查获得的速度模型的可靠性被介绍。产生Vp分发片在这个区域下面显示出复杂3-D结构并且提供三明确的矿藏的更好的理解。在表面附近，我们观察一系列地区与稍微高速度它可能反映潜在的沉积物。基于我们试图限定他们的分布的金属性的矿石的特征并且拉长了方向。

简介：北华南海架上的沙波浪被认为寡妇床形式同样稳定。为在车站LF13-2和LF13-1之间的海床的工业使用，探索的一个新回合被进行。沙波浪的间距和振幅都系统地与水深度正在改变的最新获得的数据表演。自从2003～2004证明海床当前是活跃的，重复了观察。由于表面沉积的强壮的侵蚀自从Dongsha()高举，Dongsha的架上有几乎不现代的沉积区域。在学习区域的沙材料主要从床沉积形成的侵蚀发源。水深度增长由更健全的数据主要由于侵蚀的重复回响揭示了。底部水流在Dongsha的区域是相当复杂的在水下高原。在地点9MKII，向南方退电流比强壮，向北方在地点AEM-HR充满电流，WNW病房洪水水流比ESE病房稍微强壮退当前。在地点9MKII，最大的底部水流速度是48cm/s，并且22%观察底部水流速度比20cm/s大，它遇见为沙波浪的创造要求的最小的底部水流速度。这篇文章指出今日的海洋学的状况与沙波浪形态学联合很好，并且沙飘动，这是在很大程度上在有进行中的今日的海洋学的底部水流的平衡调节并且活跃。
