14个相敏雷达（ApRES）部署在Filchner-Ronne冰架（FRIS），以测量其基础融化速率的变化。从网站沿着的伦讷抑郁症的融化率随季节变化，与季节性密集的水传播的动力学从西部冰前到腔。在FRIS空腔后面的几个站点具有两个季节性最大值的信号。从其中一个地点获得的冰下陆架海洋学数据表明，这一信号是由两条不同的路径引起的，随后是同一水源。年际变化是最强的沿着西部伦讷冰锋和西部伯克纳岛之间的直接流动路径。最高的融化发生在1999年和2018年，在冰架前夏季海冰浓度极低之后。FRIS空腔后部的年际熔化速率变化
Fourteen phase-sensitive radars (ApRES) were deployed on the Filchner-Ronne Ice Shelf (FRIS) to measure variability in its basal melt rate. Melt rates from sites along the Ronne Depression vary seasonally, consistent with the dynamics of the propagation of seasonal dense water from the western ice front into the cavity. Several sites at the back of the FRIS cavity feature a signal with two seasonal maxima. Sub-ice shelf oceanographic data available from one of the sites indicate that this signal is caused by two different pathways followed by the same source water. Inter-annual variability is strongest along a direct flow pathway between western Ronne Ice Front and western Berkner Island. Highest melting occurred in 1999 and 2018, following anomalously low summer sea-ice concentrations in front of the ice shelf. Inter-annual melt rate variability at the back of the FRIS cavity
