Summary
| Description | Operation IceBridge, a NASA airborne survey of changes in polar ice, recently completed its eighth consecutive Antarctic deployment. This page contains a wrapup video for the entire mission, as well as some footage over the Antarctic Peninsula's Larsen C Ice Shelf, and a few high definition still images. One of this year’s missions flew over a massive rift in the Larsen C. Ice shelves are the floating parts of ice streams and glaciers, and they buttress the grounded ice behind them; when ice shelves collapse, the ice behind accelerates toward the ocean, where it then adds to sea level rise. Larsen C neighbors a smaller ice shelf that disintegrated in 2002 after developing a rift similar to the one now growing in Larsen C. The IceBridge scientists measured the Larsen C fracture to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. The crack completely cuts through the ice shelf but it does not go all the way across it – once it does, it will produce an i |
