Permafrost

arctic tundra is an unglaciated, treeless landscape characterized by the presence of continuous permafrost. The tundra is vegetated by low vegetation such as grass and sedges, herbs, little bushes, lichens [...] opportunity to receive information about the state of the tundra in large areas near real time.

While determining the age of a permafrost layer in Siberia, an international team of experts set a new record: at its deepest point, the soil is at least 650,000 years old. Yet the team’s
