NASA | Flying Through the Rift

The video discusses the Pine Island Glacier in Western Antarctica, where a massive iceberg is forming. NASA's Operation Icebridge conducted detailed surveys, creating a 3D model of the ice rift. The rift is 20 miles long and 50-60 meters deep, with much more ice below water. Research teams are monitoring the glacier's flow with GPS devices to see if it speeds up post-calving. NASA satellites track the rift's daily growth, but the iceberg's calving timing is uncertain, potentially delayed by developing sea ice and the Antarctic winter.
