A previously unknown seep of petroleum hydrocarbons from the seabed was discovered in the course of multisensor satellite monitoring of the Caspian Sea, which was carried out in 2019–2020. The site of the seep source is located in the shelf area of the Caspian Sea near the Cheleken Peninsula (Turkmenistan). A retrospective analysis of the radar and optical satellite data obtained over this region for 2007–2020 was performed. The source point on the seabed in the Cheleken area was documented as the persistent location of origins of 320 oil slicks detected in satellite images taken over the region of interest in 2007–2020. A detailed map of the sea surface oil pollution caused by natural hydrocarbons showings from the seabed in the Turkmenian shelf area of the Caspian Sea was put together. It was discovered that 200 km2 of the sea surface near the emersion point has a high probability of pollution by oil films of natural origin. Further, it was shown that more than 2000 km2 of the sea surface in the area of the underwater seep is potentially exposed to oil contamination since the oil film can spread under the influence of constant wind and currents over fairly large distances — up to 35 km from the source point. A large amount of the data available allowed us to obtain statistically significant results.
Keywords: satellite remote sensing, sea surface, oil pollution, natural hydrocarbon emissions from the seabed, the Caspian Sea
