On November 10th, a 250 sq mile iceberg, or 7.5 times the size of Manahattan, calved off the Pine Island Glacier in Antarctica. A rift had opened in the glacier over 2 years ago, but the iceberg stubbornley hung on, like a broken finger nail, until now. Large calving events like this happen every 4-5 years at Pine Island Glacier (the last was 2007), but this iceberg is the largest, and broke off farther inland, than ever observed.

RISCO uses a wide range of satellite data to monitor the fast-changing portions of the Greenland and Antarctic Ice Sheets, as well as the tidewater glaciers of Alaska and other regions. RISCO aids researchers by organizing and distributing "eye-in-the-sky" data in as near real time as possible. With daily updates of new imagery, and decades of historical data, we can gain new insights into how our planet is changing.
