基于NOAA18的渤海烟台海域溢油遥感研究

Based on NOAA18 Yantai Bohai Sea Oil Spill Remote Sensing Research

概述了海洋溢油监测的国内外研究现状,并指出了研究的切入点和研究意义所在。研究采用的是NOAA18的数据,由于溢油区域与非溢油区域的比热容不同,从而引起海表面的辐射发生变化,反映在卫星图片上是灰度值不同。因此利用发生溢油区域在卫星图片上的灰度值不同而呈现出深色区域,进而在卫星图片上找出疑似溢油区域,再进行人工解译,进一步确定溢油的发生区域。以烟台"金玫瑰"号溢油事故为例,综合考虑烟台海域水文因素等,分析得出溢油发生的范围。

This paper summarizes the study of marine oil spill monitoring at home and abroad,and pointed out the starting point of this study and research.In this study,it has used the NOAA18 data,due to the non-oil spill and oil spill region that the specific heat capacity of the regional differences are reflected in the satellite images.Because the polluted sea surface changed the radiance which is gray-scale value is different.Therefore,the use of oil spill occurred on the region in satellite images showing differences in gray values which reflected the dark area on the image,and then in the satellite images to identify a suspected oil spill on the region,conducting manual interpretation,and further to determine the occurrence of oil spill area.Taking Yantai ＂Golden Rose＂ oil spills for example,comprehensive consideration of factors such as hydrology,the scope of oil spill occurred in Yantai area was analyzed.
