This paper discusses the sea oil spill detection using multispectral photographic technique. The experiment shows although sea water and oil spill have low spectral reflection values

but in 300 to 500 nm spectral region

they have larger contrast. It is possible to get good oil spill images in that spectral region. The experiment also shows that it is possible to get oil spill imaging from near ultra-violet to red spectral region with optimal spectral band selecting

but the violet-blue region is a best band

then blue-green

and the red region is poor for oil spill imaging. The results show that this technique could be used for detecting sea oil spill and sea environment pollution.
