Laser depth sounding for locating oil below water surface: A preliminary survey
Abstract
A method which uses laser reflectance to locate oil slicks below the sea surface was developed. Oil can be detected down to 10 to 15 attenuation lengths (10 to 30 m in Baltic Sea water) if the turbidity is continuous and located mostly in the cross section of the laser beam. When the oil is in small disseminated volumes, its total cross section must exceed 10% of the laser beam cross section.
