Chaun Bay

a bay (guba) of the eastern part of the East Siberian Sea, to which it is connected by the Malyi Chaun and Srednii straits. The bay is 150 km long, 100 km wide, and approximately 25 m deep. The western coast is low-lying; the eastern coast is more elevated. The entrance into the bay from the sea is blocked by two islands: Aion and Chenkul’. Chaun Bay receives many small rivers. In the summer the Aion Ice Massif forms in the bay’s entrance from old ice that is carried from high latitudes by currents. The port of Pevek is situated on Chaun Bay.
