Abstract

Contrast in the reflectivity between pure and contaminated sea surfaces is the result of two effects, namely (1) differing reflectivities of pure sea water and oil on water and (2) damping effect of the oil film on the sea waves. The problem is to estimate their separate contributions to total contrast so that the substance effect can be isolated. Its magnitude provides assessment of the oil film thickness which can be obtained for sufficiently large averaging scales. The spectral behavior and film thickness dependence of contrast have been calculated for an undisturbed sea surface. The estimate of the damping effect has been made using the Cox- Munk distributions for pure and contaminated surfaces. The method chosen has been verified during a series of tests conducted in situ from an aircraft carrying a CO₂ laser sensor operating at 10.6 micrometers .
