This Medium Resolution Imaging Spectrometer (MERIS) image is centred over the Gulf of Finland, which extends east between Finland on the north and Estonia on the south and Russia to the west. At the extreme eastern end of the gulf is the Karelian Isthmus, separating it from the Ladoga Lake. The gulf is linked with the Ladoga Lake to the east by the Neva River. To the south, the Narva River links the Gulf of Finland with Lake Peipus. The cities of Helsinki, Finland (top centre left), Tallinn, Estonia (bottom centre left) and Saint Petersburg, Russia are visible as bright areas.
