This is a project Transparent World at Caspian Sea for those interested in monitoring seal habitats from space. Environmental issues of the Caspian Sea are related to water pollution as a result of oil and gas production and transportation on the continental shelf.
In order to detect film-type pollution on the sea surface, the most efficient are radar techniques, as they are of the all-weather category. Online public results you may find here.

Oil spill in the Black Sea due to an emergency

An emergency occurred at the Caspian Pipeline Consortium's marine terminal, resulting in an oil spill into the sea. The volume of oil that entered the water is currently being specified, the company reported on its Telegram channel.

According to CPC, there is no threat of fire, and there are no casualties or injuries. All necessary forces have been deployed in the area to eliminate the consequences, oil emulsion is being collected, constant environmental monitoring is being carried out, and regular samples are being taken.

Updated. 30 cubic meters of oil entered the Black Sea during a leak during loading onto a tanker in the port of Novorossiysk, Rosprirodnadzor reports.

Integrated Film Pollution Map — July 2025

In July, we compiled the results of all recorded oil pollution incidents into an integrated map showing the sources and nature of pollution for the month.

The map also shows:
• Shipping lanes and areas of intense shipping;
• Oil companies' license areas;
• Areas of high pollution concentration — the coastal zone of Makhachkala and oil fields in the northern part of the sea.

This map allows us to see the complete picture of the month, identify persistent pollution points, and assess which areas of the sea are at greatest risk.

It is far more convenient to ignore such signals than to take responsibility for verifying information and, if spills are confirmed, investigating their circumstances, volumes, environmental consequences, identifying the culprits, taking preventive measures, etc.

Oil Spills in the Caspian Sea – Kazakh Environmental Officials “See Nothing, Hear Nothing, But Speak”

In Astana, at the conference “Caspian Ecology: Challenges and Solutions”, the coordinator of the “Transparent World on the Caspian” project reported that since 2022, satellites have recorded over 450 potential oil spills on the sea's surface. However, not a single one has been officially recognized as pollution in Kazakhstan. In June 2025, the Vice Minister of Ecology, J. Aliyev, suggested that these instances were due to misinterpretation, and that cloud shadows or other natural phenomena might have been mistaken for oil slicks.

However, such methodological issues have long been well-known, and methods for resolving them exist. Therefore, the reasons for such contradictions are most likely purely bureaucratic. Acknowledging a spill entails a number of procedures and actions.
