G51B-0165: EDGE swath altimetry for monitoring of ice-shelf rifts and rift propagation

Rift are cracks in ice shelves (glacier ice that floats on the ocean) that may be tens or hundreds of kilometers long. When rifts grow, they can help parts of the ice shelves break off, which is part of the way that some ice shelves have broken apart. When ice shelves break up, it can help glaciers flow faster into the ocean, or can let any part of the ice shelf that hasn't broken up melt faster. EDGE will make measurements that can detect the shape of rifts and can measure how they are growing. We will show how these measurements will work using data from other satellites, and will demonstrate how EDGE measurements can help us understand which ice shelves are in danger,
