NASA | Operation IceBridge Discovers Massive Crack in Ice Shelf

The video discusses a mission to study the Pine Island Glacier in West Antarctica, focusing on its rapid ice loss and the implications for sea level rise. The team compares current data with past data and satellite measurements. A recent mission to Oppenheim Glacier revealed a large crack, prompting further investigation. The team modified their flight plan to map the rift using lidar and photography, aiming to understand its development. If conditions allow, they plan to return for more observations. The video highlights the importance of being in the right place at the right time to capture significant scientific events.
