The Plavnikovyye Islands (Russian: острова Плавниковые; Ostrova Plavnikovyye) is a group of islands, in the Kara Sea eastern region, off the coast of Siberia. These islands are covered with tundra vegetation and there are many lakes and swamps. They are under snow and ice during most of the year.
The largest islands of the Plavnikovyye Archipelago are Pestsovyy Island and Kruglyy Island. Most of these islands are located and less than 10 km west of the deeply indented shores of the Taymyr Peninsula. But others, like Vardroppera Island, are far offshore. The eastern group of islands, including Kosterina and Pestsovyy, are also known as Vkhodnyye Islands.
The Plavnikovyye Islands, lie south of the small Kolosovykh peninsula. Geologically they are part of the Minina Skerries, a complex formation that includes the Kolosovykh Islands further north. This island group is located between 73° 15' and 74° 40' N and between 84° and 86° 30' E.
The sea surrounding the Plavnikovyye Islands is covered with fast ice in the winter and the climate is severe, with bitter and long winters. The surrounding sea is obstructed by pack ice even in the summer.
