Amery Ice Shelf Grounding Line Datapoints Extraction from Airborne Ice-penetrating Radar

Abstract

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 echo reflection changes between ice-bed and ice-seawater interfaces along survey lines with continuous signal and have the highest accuracy. The 'Class2' and 'Class 3' points were derived from survey lines with 'fuzzy region' with lower accuracy. The mean interval of radar-derived points is 16.4 km. The 'best case' radar-derived positions (Class 1) and those from satellite data reveals a mean separation of 1.00±1.16 km. Two products are available: (1) ice thickness data of Amery Ice Shelf from ice-penetrating radar lines; (2) radar-derived grounding line position (137 points). The ice thickness was calculated by ice surface and bottom signal and the unit is m. The radar-derived grounding line position have six fields, latitude, longitude, id, ice thickness, date (for collecting the radar data) and Class (the category of point).
