ABOUT THE SURVEY

As part of the LIMPICS Antarctica 2009/10 program at Alfred-Wegener-Institut für Polar- und Meeresforschung (AWI), Professor Yngve Kristoffersen at Dept. of Earth Science will participate in a seismic survey at Halfvarryggen¹⁾, Dronning Maud Land, Antarctica. The seismic survey will seek to compare two different seismic sources - a Vibroseis truck and dynamite. The truck, owned by University of Bergen, is furnished with snow skies and towed by tracked vehicle. Data is gathered from a 1.5 km long snow streamer towed behind the truck. The survey is in preparation of ice core drilling site selection.

The location of Dronning Maud Land - 2.5 mill. km² area - is shown on map, denoted "Norwegian claim" (in comparison, Norwegian main land is 0.4 mill. km²). The German Neumayer III station on the coast is the logistics center.

________
¹⁾ "Halfvarryggen", a name of AWI origin ... perhaps misspelling of Halvard/Hallvard, which are Norwegian names ...?

INSTRUMENTATION

Our department supplied the seismic source - the vibroseis truck. Extensive instrumentation is required to control the vibroseis sweeps that are generated. This webpage will not provide further details on this matter, however.
