Abstract

The first Vibroseis reflection survey at Antarctica was successfully carried out by the Alfred Wegener Institute in 2010. Based on the results of the vibrator in combination with a snow streamer, a grid survey was carried out at Halvfarryggen Dronning Maud Land, East Antarctica, in 2011. Halvfarryggen is a 900m thick local ice dome close to the grounding line constraining the east side of the Eksrömisen ice shelf. Here we present the first results of the Vibroseis reflection survey where we focus on the stratigraphy of the ice column and the underlying strata of the dome. From the main grid line seismic reflection data were also collected using explosives. Resolution and penetration of the Vibroseis and explosive data sets are compared and discussed as well as the logistics of each method.
