Description
Arctic tundra with frost-wedging features caused by repeated freeze-thaw processes in rocky soil, and surface water accumulation from melting permafrost. Wrangel Island, Siberian Arctic, Chukchi Sea, Russia. Wrangel Island is situated where the East Siberian and Chukchi Seas meet, 140 km off the north coast of Chukotka (aka northeastern Siberia, Chukchi Peninsula). In the Late Pleistocene, Wrangel Island was connected to the mainland of Siberia and formed a part of the Bering land bridge (aka Beringia), an area including Chukotka, Alaska, and the now-submerged continental shelf. Wrangel Island became separated from the Eurasian continent in the early Holocene epoch, around 10,000 years ago. The Arctic ecosystem on Wrangel Island is beginning to show the effects of climate change.
