Amery Ice Shelf Grounding Line Datapoints Extraction from Airborne Ice-penetrating Radar ...
We present a new grounding line product for Amery Ice Shelf - the ice-penetrating radar-derived grounding line points. The 137 grounding line points were identified by 53 survey lines from 2017 to 2020 and classified into three categories. The 'Class 1' points are extracted by significant...
