Novaya Zemlya biota. One of the most notable species present is the polar bear, whose population in the Barents Sea region is genetically distinct from other polar bear subpopulations. Novaya Zemlya Novaya Zemlya (, lit. "the new land"), also known as Nova Zembla (especially in Dutch), is an archipelago in the Arctic Ocean in northern Russia and the extreme northeast of Europe, the easternmost point of Europe lying at Cape Flissingsky on the Northern island. West of Novaya Zemlya is the Barents Sea, and to the east is the Kara Sea. Novaya Zemlya is composed of two main islands, the northern Severny
Novaya Zemlya avalanche that blocked two glacial streams and created a lake in length. Over its history as a nuclear test site, Novaya Zemlya hosted 224 nuclear detonations with a total explosive energy equivalent to 265 megatons of TNT. For comparison, all explosives used in World War II, including the detonations of two US nuclear bombs, amounted to only two megatons. In 1988–1989, "glasnost" helped make the Novaya Zemlya testing activities public knowledge, and in 1990 Greenpeace activists staged a protest at the site. The last nuclear test explosion was in 1990 (also the last for the entire Soviet Union and Russia).
