Estonia and Finland - November 8th, 2011

This orthorectified wide-swath ASAR image shows the Gulf of Finland, the easternmost arm of the Baltic Sea. It extends between Finland (to the north) and Estonia (to the south) all the way to Saint Petersburg in Russia, where the river Neva drains into it. Other major cities around the gulf include Helsinki (northern shores, near left edge) and Tallinn (southern shores, parallel to Helsinki).

The area of the gulf is 30,000 km2 (12,000 sq mi). The length (from the Hanko Peninsula to Saint Petersburg) is 400 km (250 mi) and the width varies from 70 km (43 mi) near the entrance to 130 km (81 mi) on the meridian of the island Moshnyi; in Neva Bay, it decreases to 12 km (7.5 mi). The gulf is relatively shallow with the depth decreasing from the entrance to the gulf to the continent.
