Abstract

Snow stratigraphy in Antarctica is strongly influenced by wind. This results in a complex stratigraphy. Yearly accumulation is often masked by intermediate erosion and deposition events. Kohnen-Station has a higher accu- mulation than the very low accumulation areas of East Antarctica, and therefore is suited to investigate complex stratigraphy. Here we use very high frequency GPR at 1.6 GHz to resolve stratigraphy. We compared the GPR mea- surements with detailed snow profiles measured using near-infrared photography and translucent profiles. Detailed depositional features, as dunes and cross-bedding are visible. First results show very complex patterns, which are not easily correlated to other features, and not necessarily to yearly accumulation.
