舰船尾迹气泡的遥感应用

Application of remote sensing to ship wake bubbles

对船舶尾迹所含气泡与海洋中其他物质(包括浮游植物、黄色物质、悬浮无机物)的光学特征进行了比较分析,并对船舶尾迹中不同类型气泡在单位体积数量、空间分布上的异同点进行了分析。同时,为了揭示船舶尾迹气泡在不同水体中所引起海水表观光学量的变化差异,对一、二类水体中船舶尾迹所引起海水光学量相关数据进行了比较分析,总结出各种成因气泡在表观光学特征上的区别。分析表明:该研究成果为星载光学传感器遥感获取船舶尾迹信息提供了理论参考。

The optical characteristics of bubbles contained in ship wakes and other substances which including phytoplankton, yellow substance, suspended inorganic in the ocean are compared, and the differences on the number per unit volume and on the spatial distribution of different types of bubbles are analyzed. At the same time, the apparent optical properties of various bubbles are summed up as the relevant experimental data about the sea apparent optical properties of water in Case I and Case l} are analyzed for finding the different change of apparent optical properties of sea water caused by wake bubbles at different water bodies. The analyzing result indicates that the research can provide the theoretical reference for obtaining the result information on the ship wake by optical remote sensing.
