Kandalaksha Gulf
There are four main bays or gulfs on the White Sea. These bays connect with the funnel-shaped opening to the Barents Sea via a narrow strait called "Gorlo" (, meaning "throat"). Kandalaksha Gulf lies in the western part of the White Sea; it is the deepest part of the sea, reaching 340 metres (1,115 feet). On the south, Onega Bay receives the Onega River. To the southeast, the Dvina Bay receives the Northern Dvina at the major port of Arkhangelsk. On the east side of the 'gorlo', opposite to the Kola Peninsula, is Mezen Bay. It receives the Mezen River and the Kuloy River. Other major rivers flowing into the sea are the Vyg, Niva, Umba, Varzuga and Ponoy.
