Cryosphere: Earth’s Icy Extremes Seen From Space

Floating sea ice covers about 11 million square miles of Earth’s oceans in the Arctic and Antarctic regions. It plays an important role in regulating climate and is critical for many animals. Glaciers and Ice sheets cover around 10 percent of the land area on Earth. Every continent except Australia is partially covered in ice.

Despite its extent and importance, the nature of the cryosphere makes it difficult to visit, study and understand. Because of the remote and harsh conditions throughout most of the polar regions, scientists who study them often have to rely on data collected from space for research.
