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.
