Abstract

During remote monitoring of the Persian Gulf to detect oil spills, conducted from 2017 to 2019, leaking oil on the sea surface was observed at an offshore site. The site was located 26 km west of the Sir Abu Nuyar Island in the waters of the United Arab Emirates. A more detailed analysis was conducted using remote sensing data, particularly synthetic aperture radar and optical images from the Sentinel-1 and Sentinel-2 satellites. Geographic information systems and additional cartographic, geological, and industrial data collected from several sources allowed us to conclude that, in the subject area, there was one abandoned leaking oil well, and two natural oil seeps. Using generally accepted methods, estimates of oil discharges at the site were estimated at 5–21 tons per day. Our evidence showed that the leaking and seeping oil sources in this area were both active and repeating, even prolific. The site was considered one of the largest active cases among such sites in the Persian Gulf. It is concluded modern remote sensing methods are the most effective means of observing such phenomena formed on the sea surface.

摘要

在2017年至2019年对波斯湾进行的远程监测中，发现了溢油现象，在离岸地点发现海面有漏油现象。该地点位于阿拉伯联合酋长国水域中的阿布·努亚尔爵士岛以西26公里。使用遥感数据进行了更详细的分析，特别是合成孔径雷达和Sentinel-1和Sentinel-2卫星的光学图像。地理信息系统以及从数个来源收集的其他制图，地质和工业数据使我们得出结论，在主题区域中，有1处废弃的泄漏的油井，而2处是天然油渗漏。使用公认的方法，估计该地点每天的石油排放量为5-21吨。我们的证据表明，该地区的漏油和渗漏油源既活跃又在重复，甚至多产。该地点被认为是波斯湾此类地点中最大的活跃案例之一。可以得出结论，现代遥感方法是观察在海面上形成的这种现象的最有效手段。
