Internal reflection horizons of ice shelves and ice rises in eastern Dronning Maud Land (East Antarctica) - CHIRP_20190107_01 ...

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 re...

Description
Summary: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). ... : radar type: airborne AWI UWB (MCoRDS 5), SAR focussedfrequency: 150 – 520 MHz, transmission signal: linear frequency modulated chirpcoordinator: Reinhard Drewstracing operator(s): Inka Koch, Heiko Spiegel, Leah Sophie Muhleoriginal file names: 20190107_01_002, 20190107_01_003, 20190107_01_004, 20190107_01_005, 20190107_01_006, 20190107_01_008, 20190107_01_009, 20190107_01_010--All IRHs are sorted according to depth with the shallowest layer having the smallest ID numberIRHs 2 & 5 are pattern-matched with IRHs from MCoRDS profiles collected 20190106Other IRHs are not to be matched with IRHs of the same name in MCoRDS profiles collected 20190106Visual pattern matching has been applied when gaps occur in the IRHsbasal pick is corrected to the first break ...
