Digital terrain and snow model for Aboa absolute gravity station in Decemcer 2003

Entry ID: aboa_DTM_december2003

[ Update this Record ]

Summary

Abstract: Digital terrain, snow and ice model for absolute gravity station at the Finnish
Antarctic research station Aboa, Nordenskiold Base, Dronning Maud Land, (73deg
02min S, 13deg 24min W). The surface of snow is mapped along a large number of
quasi-continuous profiles, using RTKGPS in a sledge towed by snowmobile. More
than 35 km of profiles were measured at a sampling interval of 1 m in December
2003. It is planned to repeat exactly the same tracks during future expeditions
for studying snow accumulation and its effect to absolute gravity measurement.
The studies include also a stake line with 29 measurement points for monitoring
snow surface heights and glacier motion.
