sheen, mousse, pooled or tar balls, with tar balls predominantly in 2-5mm size range
Aircraft and Autonomous Aircraft Surface Oil Detection Methods: Hyperspectral Reflectance using NASA AVIRIS on Aircraft, in visible there is little change in reflectance with oil thickness, but there is a difference in the Infrared.
Aircraft and Autonomous Aircraft Surface Oil Detection Methods: IR Variations in absorbance with oil water mixtures and thickness, with 40:60 having highest reflectance
Aircraft and Autonomous Aircraft Surface Oil Detection Methods: AVIRIS flight lines May 17; background image is MODIS Terra satellite. Swath width is @5.5km
Average UAVSAR radar intensity over the Deepwater Horizon spill site. Ships are dark blue dots; oil show as yellow/reddish (lower intensity).
Autonomous Aircraft Surface Oil Detection: Comparison of AVIRIS Hyperspectral with LIDAR methods, note much higher spectral resolution using lidar methods, providing potentially greater accuracy of thickness and volume estimates. Lidar methods offer potential for future but need development.
Autonomous Aircraft Surface Oil Detection Methods: Coal Oil Point off Santa Barbara, a natural continuous seep for testing UAS oil thickness technologies including LIDAR.
