Summary:
With new tools and technology, scientists are getting a first look at strange features and puzzling behaviors on the frozen Antarctic continent. Icy tributaries feed giant, frozen streams that churn icebergs into the sea. Rows of long, sinuous snow dunes on the East Antarctic plateau are blown by fierce, constant winds, but appear to stay frozen in place for decades. Hundreds of meters below ice ridges, warped ice layers record the dynamic history of some ice streams, and the quiet stability of others.
