Novaya Zemlya largest number of fjords in the Russian Federation. Novaya Zemlya separates the Barents Sea from the Kara Sea. The total area is about . The highest mountain is located on the Northern island and is 1,547 meters (5,075 ft) high. Compared to other regions that were under large ice sheets during the last glacial period, Novaya Zemlya shows relatively little isostatic rebound. Possibly this is indebted to a counter-effect created by the growth of glaciers during the last few thousand years. The ecology of Novaya Zemlya is influenced by its severe climate, but the region nevertheless supports a diversity of
Novaya Zemlya effect gradient. The sunlight must bend to the Earth's curvature at least 400 km to allow an elevation rise of 5° for sight of the solar disk. The first person to record the phenomenon was Gerrit de Veer, a member of Willem Barentsz's ill-fated third expedition into the north polar region in 1596–1597. Trapped by the ice, the party was forced to stay for the winter in a makeshift lodge on the archipelago of Novaya Zemlya and endure the polar night. On January 24, 1597, De Veer and another crew member claimed to have seen the Sun appear above the horizon,
