用光学卫星进行水下turbulence探测
Submerged turbulence detection with optical satellites
摘要：
在2002年、2003年和2004年秋季期间，在夏威夷的马马拉湾进行了三次重大的海洋学考察。这些都是RASP人为遥感方案的一部分。Ikonos和Quickbird的海面闪烁光学卫星图像显示，从檀香山沙岛市政排水口扩散器到20 km范围内的区域中，平均面积为平方公里的斑块中有约100 m的光谱异常。为了确定这一现象背后的机制，RASP考察队监测了排水口附近的水域，在异常和周围背景区域安装了水文、光学和湍流微结构传感器。分析了2x10^4微结构斑块的拖曳轨迹和平均湍流参数，以了解复杂湍流、化石湍流和僵尸湍流近垂直内波输运过程。主要的机制似乎是通用的分层自然流体，包括行星和恒星大气，并被称为光束僵尸湍流脉泽行动（BZTMA）。大部分底部湍流动能转化为~100 m的化石湍流波。这些激活二级（僵尸）湍流在出口化石湍流补丁，传输热量，质量，化学物质，动量和信息垂直到海面检测在一个有效的微波激射器行动。运输是在间歇性的混合烟囱中进行的。
英文摘要：
During fall periods in 2002, 2003 and 2004 three major oceanographic expeditions were carried out in Mamala Bay, Hawaii. These were part of the RASP Remote Anthropogenic Sensing Program. Ikonos and Quickbird optical satellite images of sea surface glint revealed ~100 m spectral anomalies in km^2 averaging patches in regions leading from the Honolulu Sand Island Municipal Outfall diffuser to distances up to 20 km. To determine the mechanisms behind this phenomenon, the RASP expeditions monitored the waters adjacent to the outfall with an array of hydrographic, optical and turbulence microstructure sensors in anomaly and ambient background regions. Drogue tracks and mean turbulence parameters for 2x10^4 microstructure patches were analyzed to understand complex turbulence, fossil turbulence and zombie turbulence near-vertical internal wave transport processes. The dominant mechanism appears to be generic to stratified natural fluids including planet and star atmospheres and is termed beamed zombie turbulence maser action (BZTMA). Most of the bottom turbulent kinetic energy is converted to ~100 m fossil turbulence waves. These activate secondary (zombie) turbulence in outfall fossil turbulence patches that transmit heat, mass, chemical species, momentum and information vertically to the sea surface for detection in an efficient maser action. The transport is beamed in intermittent mixing chimneys.
