Radargram (IMAGE)
Caption
Figure 2. A high-resolution radargram in the vicinity of the confirmed drill site. It shows the traveltime of the radar wave on the vertical axis, with 30 microseconds roughly corresponding to 2550 m and distance along the line on the horizontal axis. The 1.5 million year old ice is located around 31 microseconds, where the well-preserved stratigraphy, visible as layers, transits into the basal layer, where not reflections are visible. The dark feature at the bottom is the bedrock underneath the ice sheet. (White dots at the bedrock and hyperbolas are artefacts from processing.)
