An Examination of Antarctic’s Larsen Ice Shelf Changes, in 3/8/17 PBS NewsHour Video

The section-by-section disappearance of Antarctica’s Larsen Ice Shelf is the focus of “How scientists are tracking a massive iceberg in the making,” broadcast on March 8, 2017, on the PBS NewsHour.  The 5 min./55 second video, available online at http://www.pbs.org/newshour/bb/scientists-tracking-massive-iceberg-making/, discusses how an early 2017 rift in the ice shelf is one of the largest ever seen, separating a section approximately the size of the state of Delaware.  This follows the loss in 2002 of a section in that was approximately the size of Rhode Island.  The report describes some of the satellite technology and imagery used to track such large-scale changes.  More information on changes to the Larsen Ice Shelf is available from the National Aeronautic and Space Agency (NASA), “Antarctica’s Changing Larsen Ice Shelf,” online at https://www.nasa.gov/image-feature/antarctica-s-changing-larsen-ice-shelf.
