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.

TASS noted the scale of the Caspian Sea pollution according to satellite data

The TASS agency, analyzing the results of the report of the “transparent world in the Caspian” for 2023–2024, separately emphasized the important conclusion of ecologists: despite the large number of discovered oil pollution (about 537 sq. Km in two years), key habitats of the Caspian seal are still outside the risk zone.

The agency paid special attention to the effectiveness of satellite monitoring, which allowed not only to quickly fix oil spots, but also for the first time to compare their location with the range of reproduction and riding seals.

It is extremely valuable that large Russian media began to illuminate the problem of Caspian pollution. After all, it is precisely broad public attention that can push the company and the authorities to take real measures to protect the unique nature of the sea and its inhabitants.

Within the framework of the project, a comparison of the areas of the Nuthel, the watering and reproduction of Caspian tules with the areas of the greatest concentration of the spots of film pollution on the surface of the sea found as part of the monitoring was performed. Previously, it can be argued that the main areas of the seal and the concentration of oil pollution are spatially spaced.

1. One of the main sources of anthropogenic film pollution of the Northern and Middle Caspian is international and local shipping. Most often, film pollution appeared on or in shipping tracks, in areas of anchor parking and raids. As part of the monitoring, the two most loaded shipping routes were identified, on which oil industry often occur.
