Sakhalin Gulf
Russia
Sakhalin Gulf is a gulf in the Sea of Okhotsk between continental Russia (north of the Amur's mouth) and the Schmidt Peninsula, at the northern tip of Sakhalin Island. The width of the gulf reaches up to 160 km (99 mi). It is covered with ice from mid-November until late April, but north winds can leave the bay blocked with ice until July. The port of Moskalvo is located on the eastern shore of the Sakhalin Gulf, close to Ush Island.
