Abstract:
Local snow surface heights were sampled in December 2018 across a traverse of ~ 100 km near Kohnen Station. They were used to quantify surface roughness and its relation to stratigraphic noise in isotope records from firn cores. At six different locations (D2, C4, C5, D7, D24, D38) snow heights were measured along the positioning of the firn cores (along 60 m), with a 1-2 m horizontal resolution and an accuracy of ∓ 1 cm using a Geodät levelling device. The measurements were done perpendicularly to the overall large scale wind direction.
