In this study, sea surface scattering with and without surfactants is predicted using the two-scale boundary perturbation model (BPM) advanced integral equation (AIEM) augmented two different damping models, i.e., Marangoni one of local balance (MLB). Numerical predictions are showcased for both mineral oil biogenic slicks. They contrasted actual satellite Synthetic Aperture Radar (SAR) measurements collected at X-band by German TerraSAR-X sensor over plant slicks known origin. Experimental results show that BPM more suitable predicting normalized radar cross section ratio (biogenic) contrast, AIEM combined MLB in a better agreement SAR
