Internal reflection horizons of ice shelves and ice rises in eastern Dronning Maud Land (East Antarctica) - Belare 2010

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输送，其演化过程取决于表面物质累积、底部消融与冰动力学的时空分布格局。这些过程塑造了冰地层结构，可通过雷达成像并以内部反射层位（internal reflection horizons, IRHs）的形式实现数字化处理。本研究整合了三项航空及地面探测获取的内部反射层位数据，这些探测覆盖了东南极德龙宁·莫德地沿海区域的三处冰隆与冰架。
