Reference work entry
  1. 1.

    A bay in Chukotka that belongs to the eastern part of the East Siberian Sea Basin and connects to it through three straits: the Lesser Chaun Strait (on the western side of Ayon Island), the Middle Chaun Strait (between Bolshoy Routan Island and Ayon Island), and Pevek (on the eastern side of Bolshoy Routan). The depth of the bay does not exceed 20 m, with the exception of the Pevek Strait, where it reaches more than 30 m. The basin of the bay contains a large number of small rivers. The Palyavaam River flows into the bay. At the cape of Valkumey in Chaunskaya Bay, rich deposits of tin were discovered, which lead to the establishing in the Arctic regions of Chukotka of the first mining enterprises for the extraction of tin, as well as boosted the construction of the port in Pevek. A winter road passes through the bay, from Pevek to Baranikha. An airport is located on the eastern coast.
