Vibroseis versus Explosive Reflection Seismics at the local dome Halvfarryggen; Antarctica.

Description
Summary:The first Vibroseis reflection survey at Antarctica was successfully carried out by AWI in 2010. Based on the results the vibrator in combination with a snow streamer gave, a grid survey was carried out at Halvfarryggen in 2011. Halvfarryggen is a local 900m thick ice dome close to the grounding line in the vicinity of the German research station Neumayer III. Here we present the results of the Vibroseis reflection survey where we focus on the stratigraphy of 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.
