evidence: Geostatistical analysis of natural oil seepage using radar imagery—a case study in Qaruh Island, the State of Kuwait [...] The issue of natural oil seepage is one of the challenges in the Kuwaiti marine environment. Many observations have been made about the existence of a natural oil seepage near Qaruh Island, which is a small island located in the northwest of the Arabian Gulf. This study aims to take advantage of active remote sensing (radar imagery) in monitoring this phenomenon, both spatially and statistically. One hundred eleven images taken from Sentinel-1 in the period from September 2014 to September 2017 were analyzed. Thirty-four oil slicks were detected, with a ratio of one caused every 3 days. Additionally, the spatial central tendency measures were identified. The results showed that the average extension of the phenomenon was 68.2 km2, while it reached a maximum of 225.8 km2, with a minimum of 12.5 km2—a range of 213.3 km2. The mean and median centers are located to the southeast of Qaruh Island at a direction of about 148° and 150° and distance of 9.2 km and 7 km, respectively. The directional distribution cycles clarify that the phenomenon was directed to the northwest and southeast. The accuracy of Sentinel-1 data has been verified by Landsat 8 images in true and false colors. [...] Albanai, J.A., Mahamat, A.A. & Abdelfatah, S.A.
