Internal reflection horizons of ice shelves and ice rises in eastern Dronning Maud Land (East Antarctica) - Bewise 2012

Ice shelves regulate ice flow from the Antarctic ice sheet towards the ocean and their evolution depends on spatiotemporal patterns of surface accumulation, basal melt, and ice dynamics. These processes shape the ice stratigraphy, which can be imaged by radar and digitized in the form of internal reflection horizons (IRHs). Here, we synthesized IRHs from three airborne and ground-based surveys covering three ice rises and shelves in coastal eastern Dronning Maud Land (East Antarctica).冰架调控南极冰盖向海洋的冰流运动，其演化过程取决于表面物质积累、底部消融与冰动力学的时空格局。上述过程塑造了冰地层结构，该结构可通过雷达成像，并以内部反射层（internal reflection horizons，IRHs）的形式实现数字化记录。本研究整合了覆盖东南极洲毛德皇后地东部沿海三处冰隆与冰架的三项航空及地面探测所获取的内部反射层数据。
