The thickness of oil spill can be measured by microwave reflection. A drone directs microwave beam from above. The two oil surfaces reflect microwave back to the drone. The refractive index is 1.5 for crude oil, and 1.34 for sea water. At one spot, the strongest reflected frequency (zeroth order interference) is 6 GHz. The oil thickness is mm.
